“ pip install unroll”：“ python setup.py egg_info”失败，错误代码为1

This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.

Error code 1 is defined in errno.h and means Operation not permitted.

About your error

Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.

If it’s already installed, try

pip install --upgrade setuptools

If it’s already up to date, check that the module ez_setup is not missing. If it is, then

pip install ez_setup

Then try again

pip install unroll

If it’s still not working, maybe pip didn’t install/upgrade setup_tools properly so you might want to try

easy_install -U setuptools

And again

pip install unroll

这是一些指南，解释了我通常如何在Python + Windows上安装新软件包。看来您使用的是Windows路径，因此此答案将遵循特定的SO：

我从不使用系统范围的Python安装。我只使用virtualenvs，通常我会尝试使用最新版本的2.x和3.x。
我的第一次尝试总是pip install package_i_want在某些Visual Studio命令提示符下进行。什么Visual Studio命令提示符？好吧，理想情况下是与用来构建Python的Visual Studio相匹配的Visual Studio。例如，假设您的Python安装提示Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32。可以在此处找到用于编译Python的Visual Studio版本，因此v1500表示我将使用vs2008 x64命令提示符
如果上一步由于某种原因而失败，我只是尝试使用 easy_install package_i_want
如果上一步由于某种原因失败，我将转到gohlke网站，并检查我的包裹是否在那儿。如果是这样，我很幸运，我将其下载到virtualenv中，然后使用命令提示符转到该位置，然后执行pip install package_i_want.whl
如果上一步没有成功，我将尝试自己制作轮子，一旦生成，我将尝试使用 pip install package_i_want.whl

现在，如果我们专注于您的特定问题，那么您将很难安装展开软件包。似乎最快的安装方式是执行以下操作：

git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
将创建的dist文件夹中生成的unroll-0.1.0-py2-none-any.whl文件复制到virtualenv中。
pip install unroll-0.1.0-py2-none-any.whl

这样，它将安装没有任何问题。要检查它是否确实有效，只需登录Python安装并尝试import unroll，不要抱怨。

最后一点：这种方法几乎在99％的时间内都有效，有时您会发现一些特定于Unix或Mac OS X的pip程序包，在这种情况下，恐怕最好的方法是Windows版本正在向主要开发人员发布一些问题，或者您可以通过自己移植到Windows来获得一些乐趣（如果不走运，通常需要几个小时）：）

Here’s a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you’re using Windows paths, so this answer will stick to that particular SO:

I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let’s say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I’d be using vs2008 x64 command prompt
If the previous step failed for some reason I just try using easy_install package_i_want
If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it’s so, I’m lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
If the previous step didn’t succeed I’ll just try to build the wheel myself and once it’s generated I’ll try to install it with pip install package_i_want.whl

Now, if we focus in your specific problem, where you’re having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:

git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
pip install unroll-0.1.0-py2-none-any.whl

That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn’t complain.

One last note: This method works almost 99% of the time, and sometimes you’ll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I’m afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you’re not lucky) :)

我完全陷入了与相同的错误psycopg2。看来我在安装Python和相关软件包时跳过了几个步骤。

sudo apt-get install python-dev libpq-dev
转到您的虚拟环境
pip install psycopg2

（在您的情况下，您需要替换psycopg2遇到问题的软件包。）

它无缝地工作。

I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.

sudo apt-get install python-dev libpq-dev
Go to your virtual env
pip install psycopg2

(In your case you need to replace psycopg2 with the package you have an issue with.)

It worked seamlessly.

我有同样的问题。

问题是：

pyparsing 2.2已经安装好了，我requirements.txt正在尝试安装pyparsing 2.0.1，抛出此错误

上下文：我使用的是virtualenv，似乎2.2来自我的全局操作系统Python site-packages，但是即使带有--no-site-packages标志（默认为上一个virtualenv中的默认标志），2.2仍然存在。肯定是因为我从他们的网站安装了Python，并将Python库添加到了我的$PATH。

也许一个pip install --ignore-installed会工作。

解决方案：因为我需要向前移动，我只是删除了pyparsing==2.0.1从我的requirements.txt。

I had the same problem.

The problem was:

pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error

Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.

Maybe a pip install --ignore-installed would have worked.

Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.

尝试使用pip安装Python模块时遇到了相同的错误代码。@Hackndo指出文档指出了安全问题。

基于该答案，我的问题通过运行带有sudo前缀的pip install命令得以解决：

sudo pip install python-mpd2

I ran into the same error code when trying to install a Python module with pip. @Hackndo noted that the documentation indicate a security issue.

Based on that answer, my problem was solved by running the pip install command with sudo prefixed:

这意味着pip中的某些软件包较旧或未正确安装。

尝试检查版本，然后升级pip。如果可行，请使用自动删除。
如果pip命令始终对任何命令显示错误或冻结，等等。
最好的解决方案是将其卸载或完全删除。
安装一个新的点，然后更新和升级您的系统。
我给出了在此处新鲜安装pip的解决方案-python：无法打开文件get-pip.py错误2]没有此类文件或目录

That means some packages in pip are old or not correctly installed.

Try checking version and then upgrading pip.Use auto remove if that works.
If the pip command shows an error all the time for any command or it freezes, etc.
The best solution is to uninstall it or remove it completely.
Install a fresh pip and then update and upgrade your system.
I have given a solution to installing pip fresh here – python: can’t open file get-pip.py error 2] no such file or directory

这对我来说是更简单的方法：

pip3 install –upgrade setuptools警告：pip正在由旧的脚本包装程序调用。这将在以后的pip版本中失败。请参阅https://github.com/pypa/pip/issues/5599，以获取有关解决基本问题的建议。

******为了避免此问题，您可以使用-m pip调用Python，而不是直接运行pip。******

使用python3 -m pip“命令”例如：python3 -m pip install –user pyqt5

pip3 install –upgrade setuptools WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.

******To avoid this problem you can invoke Python with ‘-m pip’ instead of running pip directly.******

use python3 -m pip “command” eg: python3 -m pip install –user pyqt5

我在使用相同的错误消息时遇到了同样的问题，但是在Ubuntu 16.04 LTS（Xenial Xerus）上却相反：

命令“ python setup.py egg_info”在/ tmp / pip-install-w71uo1rg / poster /中失败，错误代码为1

我测试了上面提供的所有解决方案，但没有一个对我有用。我阅读了完整的TraceBack，发现我必须使用python版本2.7创建虚拟环境（默认情况下使用Python 3.5）：

virtualenv --python=/usr/bin/python2.7 my_venv

激活它后，我将pip install unirest成功运行。

I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:

Command “python setup.py egg_info” failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/

I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):

virtualenv --python=/usr/bin/python2.7 my_venv

Once I activated it, I run pip install unirest successfully.

我遇到了同样的问题，可以通过以下操作解决。

Windows Python需要通过SDK安装的Visual C ++库来构建代码，例如通过setuptools.extension.Extension或numpy.distutils.core.Extension。例如，在Windows中使用Python构建f2py模块需要安装上述Visual C ++ SDK。在Linux和Mac上，C ++库随编译器一起安装。

https://www.scivision.co/python-windows-visual-c++-14-required/

I had the same problem and was able to fix by doing the following.

Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
