问题:Python和pip,列出可用的软件包的所有版本?

给定可以与pip一起安装的Python软件包的名称,是否有任何方法可以找到pip可以安装的所有可能版本的列表?现在是反复试验。

我正在尝试为第三方库安装一个版本,但是最新版本太新了,进行了向后不兼容的更改。所以我想以某种方式列出pip知道的所有版本,以便我可以对其进行测试。

Given the name of a Python package that can be installed with pip, is there any way to find out a list of all the possible versions of it that pip could install? Right now it’s trial and error.

I’m trying to install a version for a third party library, but the newest version is too new, there were backwards incompatible changes made. So I’d like to somehow have a list of all the versions that pip knows about, so that I can test them.

(更新:截至2020年3月,许多人报告说,通过安装的蛋黄pip install yolk3k只能返回最新版本。 克里斯的回答似乎最支持我,并为我工作)

pastebin上的脚本可以正常工作。但是,如果您要使用多个环境/主机,这不是很方便,因为您每次都必须复制/创建它。

更好的全方位解决方案是使用yolk3k,该软件可与pip一起安装。例如,查看可用的Django版本:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k2012年yolk停止开发的原版的叉子。尽管已不再维护(如下面的注释所示),yolkyolk3k似乎并支持Python 3。

注意:我不参与yolk3k的开发。如果某些事情似乎无法正常工作,则在此处发表评论不会有太大的不同。请改用yolk3k问题追踪器,并考虑提交修订(如果可能)。

(update: As of March 2020, many people have reported that yolk, installed via pip install yolk3k, only returns latest version. Chris’s answer seems to have the most upvotes and worked for me)

The script at pastebin does work. However it’s not very convenient if you’re working with multiple environments/hosts because you will have to copy/create it every time.

A better all-around solution would be to use yolk3k, which is available to install with pip. E.g. to see what versions of Django are available:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k is a fork of the original yolk which ceased development in 2012. Though yolk is no longer maintained (as indicated in comments below), yolk3k appears to be and supports Python 3.

Note: I am not involved in the development of yolk3k. If something doesn’t seem to work as it should, leaving a comment here should not make much difference. Use the yolk3k issue tracker instead and consider submitting a fix, if possible.

用于PIP> = 9.0使用

$ pip install pylibmc==
Collecting pylibmc==
  Could not find a version that satisfies the requirement pylibmc== (from 
  versions: 0.2, 0.3, 0.4, 0.5.1, 0.5.2, 0.5.3, 0.5.4, 0.5.5, 0.5, 0.6.1, 0.6,

No matching distribution found for pylibmc==

–将打印所有可用版本,而无需实际下载或安装任何其他软件包。

对于pip <9.0使用

pip install pylibmc==blork

在哪里blork可以是不是有效版本号的任何字符串。

For pip >= 9.0 use

$ pip install pylibmc==
Collecting pylibmc==
  Could not find a version that satisfies the requirement pylibmc== (from 
  versions: 0.2, 0.3, 0.4, 0.5.1, 0.5.2, 0.5.3, 0.5.4, 0.5.5, 0.5, 0.6.1, 0.6,

No matching distribution found for pylibmc==

– all the available versions will be printed without actually downloading or installing any additional packages.

For pip < 9.0 use

pip install pylibmc==blork

where blork can be any string that is not a valid version number.

您不需要第三方软件包即可获取此信息。pypi为以下所有包提供了简单的JSON feed

https://pypi.python.org/pypi/{PKG_NAME}/json

以下是一些仅使用获取所有版本的标准库的Python代码。

import json
import urllib2
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.python.org/pypi/%s/json" % (package_name,)
    data = json.load(urllib2.urlopen(urllib2.Request(url)))
    versions = data["releases"].keys()
    versions.sort(key=StrictVersion)
    return versions

print "\n".join(versions("scikit-image"))

该代码打印出来(截至2015年2月23日):

0.7.2
0.8.0
0.8.1
0.8.2
0.9.0
0.9.1
0.9.2
0.9.3
0.10.0
0.10.1

You don’t need a third party package to get this information. pypi provides simple JSON feeds for all packages under

https://pypi.python.org/pypi/{PKG_NAME}/json

Here’s some Python code using only the standard library which gets all versions.

import json
import urllib2
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.python.org/pypi/%s/json" % (package_name,)
    data = json.load(urllib2.urlopen(urllib2.Request(url)))
    versions = data["releases"].keys()
    versions.sort(key=StrictVersion)
    return versions

print "\n".join(versions("scikit-image"))

That code prints (as of Feb 23rd, 2015):

0.7.2
0.8.0
0.8.1
0.8.2
0.9.0
0.9.1
0.9.2
0.9.3
0.10.0
0.10.1

我想出了简单的bash脚本。感谢jq的作者。

#!/bin/bash
set -e

PACKAGE_JSON_URL="https://pypi.org/pypi/${1}/json"

curl -s "$PACKAGE_JSON_URL" | jq  -r '.releases | keys | .[]' | sort -V

更新:添加按版本号排序。

I came up with dead-simple bash script. Thanks to jq‘s author.

#!/bin/bash
set -e

PACKAGE_JSON_URL="https://pypi.org/pypi/${1}/json"

curl -s "$PACKAGE_JSON_URL" | jq  -r '.releases | keys | .[]' | sort -V

Update: Add sorting by version number.

您可以使用yolk3k软件包而不是yolk。yolk3k是原始蛋黄的叉子,它同时支持python2和3。

https://github.com/myint/yolk

pip install yolk3k

You could the yolk3k package instead of yolk. yolk3k is a fork from the original yolk and it supports both python2 and 3.

pip install yolk3k

看了一段时间的pip代码后,看起来可以在中的PackageFinder类中找到负责定位软件包的代码pip.index。它的方法find_requirement查找的版本InstallRequirement,但不幸的是仅返回最新版本。

下面的代码几乎是原始函数的1:1副本,第114行的return更改为返回所有版本。

该脚本将一个包名称作为第一个也是唯一的参数,并返回所有版本。

After looking at pip’s code for a while, it looks like the code responsible for locating packages can be found in the PackageFinder class in pip.index. Its method find_requirement looks up the versions of a InstallRequirement, but unfortunately only returns the most recent version.

The code below is almost a 1:1 copy of the original function, with the return in line 114 changed to return all versions.

The script expects one package name as first and only argument and returns all versions.

I can’t guarantee for the correctness, as I’m not familiar with pip’s code. But hopefully this helps.

您可以使用这个小的Python 3脚本(仅使用标准库模块)来使用JSON API从PyPI抓取软件包的可用版本列表,并以相反的时间顺序打印它们。不像其他一些Python的解决方案张贴在这里,但这并不松散的版本一样突破django2.2rc1还是uwsgi2.0.17.1

#!/usr/bin/env python3

import json
import sys
from urllib import request    
from pkg_resources import parse_version    

def versions(pkg_name):
    url = f'https://pypi.python.org/pypi/{pkg_name}/json'
    releases = json.loads(request.urlopen(url).read())['releases']
    return sorted(releases, key=parse_version, reverse=True)    

if __name__ == '__main__':
    print(*versions(sys.argv[1]), sep='\n')

保存脚本并以包名称作为参数运行它,例如:

python versions.py django
3.0a1
2.2.5
2.2.4
2.2.3
2.2.2
2.2.1
2.2
2.2rc1
...

You can use this small Python 3 script (using only standard library modules) to grab the list of available versions for a package from PyPI using JSON API and print them in reverse chronological order. Unlike some other Python solutions posted here, this doesn’t break on loose versions like django‘s 2.2rc1 or uwsgi‘s 2.0.17.1:

#!/usr/bin/env python3

import json
import sys
from urllib import request    
from pkg_resources import parse_version    

def versions(pkg_name):
    url = f'https://pypi.python.org/pypi/{pkg_name}/json'
    releases = json.loads(request.urlopen(url).read())['releases']
    return sorted(releases, key=parse_version, reverse=True)    

if __name__ == '__main__':
    print(*versions(sys.argv[1]), sep='\n')

Save the script and run it with the package name as an argument, e.g.:

python versions.py django
3.0a1
2.2.5
2.2.4
2.2.3
2.2.2
2.2.1
2.2
2.2rc1
...

这对我在OSX上有效:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

它每行返回一个列表:

1.1.0rc1
1.1.0rc2
1.1.0
1.2.0rc1
1.2.0rc2
1.2.0rc3
1.2.0rc4
1.2.0
1.3.0rc1
1.3.0rc2
1.3.0rc3
1.3.0
1.3.1
1.3.2
1.3.3
1.4.0rc1
1.4.0rc2
1.4.0rc3

1.4.1
1.4.2
1.5.0rc1
1.5.0rc2
1.5.0rc3
1.5.0
1.5.1
1.5.2
1.6.0rc1
1.6.0

1.8.0rc2
1.8.0
1.8.1
1.9.0rc1
1.9.0rc2
1.9.0rc3
1.9.0rc4
1.9.0
1.10.0rc1
1.10.0rc2
1.10.0

或获取可用的最新版本:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1
1.10.0rc2

请记住gsort,必须安装(在OSX上)以解析版本。您可以使用安装brew install coreutils

This works for me on OSX:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

It returns the list one per line:

1.1.0rc1
1.1.0rc2
1.1.0
1.2.0rc1
1.2.0rc2
1.2.0rc3
1.2.0rc4
1.2.0
1.3.0rc1
1.3.0rc2
1.3.0rc3

1.4.0rc3
1.4.0
1.4.1
1.4.2
1.5.0rc1
1.5.0rc2
1.5.0rc3
1.5.0
1.5.1
1.5.2
1.6.0rc1
1.6.0
1.6.1
1.6.2
1.7.0rc1
1.7.0rc2
1.7.0
1.7.1
1.8.0rc1
1.8.0rc2
1.8.0
1.8.1
1.9.0rc1
1.9.0rc2
1.9.0rc3
1.9.0rc4
1.9.0
1.10.0rc1
1.10.0rc2
1.10.0

Or to get the latest version available:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1
1.10.0rc2

Keep in mind gsort has to be installed (on OSX) to parse the versions. You can install it with brew install coreutils

我的项目luddite具有此功能。

用法示例:

>>> import luddite
>>> luddite.get_versions_pypi("python-dateutil")
('0.1', '0.3', '0.4', '0.5', '1.0', '1.1', '1.2', '1.4', '1.4.1', '1.5', '2.0', '2.1', '2.2', '2.3', '2.4.0', '2.4.1', '2.4.2', '2.5.0', '2.5.1', '2.5.2', '2.5.3', '2.6.0', '2.6.1', '2.7.0', '2.7.1', '2.7.2', '2.7.3', '2.7.4', '2.7.5', '2.8.0')

通过查询https://pypi.org/的json API,它列出了可用软件包的所有版本。

My project luddite has this feature.

Example usage:

>>> import luddite
>>> luddite.get_versions_pypi("python-dateutil")
('0.1', '0.3', '0.4', '0.5', '1.0', '1.1', '1.2', '1.4', '1.4.1', '1.5', '2.0', '2.1', '2.2', '2.3', '2.4.0', '2.4.1', '2.4.2', '2.5.0', '2.5.1', '2.5.2', '2.5.3', '2.6.0', '2.6.1', '2.7.0', '2.7.1', '2.7.2', '2.7.3', '2.7.4', '2.7.5', '2.8.0')

It lists all versions of a package available, by querying the json API of https://pypi.org/

我没有任何运气yolkyolk3kpip install -v可是所以最后我用这个(埃里克蒋介石的回答适合到Python 3):

import json
import requests
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.python.org/pypi/{}/json".format(package_name)
    data = requests.get(url).json()
    return sorted(list(data["releases"].keys()), key=StrictVersion, reverse=True)

>>> print("\n".join(versions("gunicorn")))
19.1.1
19.1.0
19.0.0
18.0
17.5
0.17.4
0.17.3
...

I didn’t have any luck with yolk, yolk3k or pip install -v but so I ended up using this (adapted to Python 3 from eric chiang’s answer):

import json
import requests
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.python.org/pypi/{}/json".format(package_name)
    data = requests.get(url).json()
    return sorted(list(data["releases"].keys()), key=StrictVersion, reverse=True)

>>> print("\n".join(versions("gunicorn")))
19.1.1
19.1.0
19.0.0
18.0
17.5
0.17.4

另一种解决方案是使用Warehouse API:

https://warehouse.readthedocs.io/api-reference/json/#release

例如Flask:

import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())

将打印:

dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])

Alternative solution is to use the Warehouse APIs:

https://warehouse.readthedocs.io/api-reference/json/#release

For instance for Flask:

import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())

will print:

dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])

bash仅依赖于python自身的简单脚本(我假设应该在问题的上下文中进行安装)以及curl或之一wget。假设您已setuptools安装软件包以对版本进行排序(几乎始终已安装)。它不依赖外部依赖项,例如:

  • jq 可能不存在;
  • grep并且awk在Linux和macOS上的行为可能有所不同。
curl --silent --location https://pypi.org/pypi/requests/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))"

带有注释的较长版本。

将包名称放入变量中:

PACKAGE=requests

获取版本(使用curl):

VERSIONS=$(curl --silent --location https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

获取版本(使用wget):

VERSIONS=$(wget -qO- https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

打印排序版本:

echo $VERSIONS

Simple bash script that relies only on python itself (I assume that in the context of the question it should be installed) and one of curl or wget. It has an assumption that you have setuptools package installed to sort versions (almost always installed). It doesn’t rely on external dependencies such as:

  • jq which may not be present;
  • grep and awk that may behave differently on Linux and macOS.
curl --silent --location https://pypi.org/pypi/requests/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))"

A little bit longer version with comments.

Put the package name into a variable:

PACKAGE=requests

Get versions (using curl):

VERSIONS=$(curl --silent --location https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

Get versions (using wget):

VERSIONS=$(wget -qO- https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

Print sorted versions:

echo $VERSIONS

我的看法是结合了几个已发布的答案,并进行了一些修改,以使其在运行中的python环境中更易于使用。

这个想法是提供一个全新的命令(在install命令之后建模),为您提供要使用的软件包查找程序的实例。好处是,它可以与pip支持并读取本地pip配置文件的任何索引一起使用并使用,因此您可以获得与普通pip安装相同的正确结果。

我已经尝试使其与pip v 9.x和10.x兼容。.但是仅在9.x上尝试过

My take is a combination of a couple of posted answers, with some modifications to make them easier to use from within a running python environment.

The idea is to provide a entirely new command (modeled after the install command) that gives you an instance of the package finder to use. The upside is that it works with, and uses, any indexes that pip supports and reads your local pip configuration files, so you get the correct results as you would with a normal pip install.

I’ve made an attempt at making it compatible with both pip v 9.x and 10.x.. but only tried it on 9.x
