问题:virtualenvwrapper和Python 3
我在ubuntu lucid上安装了python 3.3.1并成功创建了virtualenv,如下所示
virtualenv envpy331 --python=/usr/local/bin/python3.3
这envpy331
在我的主目录上创建了一个文件夹。
我也已经virtualenvwrapper
安装了。但是在文档中仅支持的2.4-2.7
版本。python
是否有人试图组织python3
virtualenv?如果是这样,您能告诉我如何吗?
I installed python 3.3.1 on ubuntu lucid and successfully created a virtualenv as below
virtualenv envpy331 --python=/usr/local/bin/python3.3
this created a folder envpy331
on my home dir.
I also have virtualenvwrapper
installed.But in the docs only 2.4-2.7
versions of python
are supported..Has anyone tried to organize the python3
virtualenv ? If so, can you tell me how ?

如果您已经安装了python3以及virtualenvwrapper,那么在虚拟环境中使用python3的唯一操作就是使用以下命令创建环境:
which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
或者,(至少在使用brew的OSX上):
mkvirtualenv --python=`which python3` nameOfEnvironment
开始使用环境,您将看到在键入python后立即开始使用python3
If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:
which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
Or, (at least on OSX using brew):
mkvirtualenv --python=`which python3` nameOfEnvironment
Start using the environment and you’ll see that as soon as you type python you’ll start using python3

您可以使virtualenvwrapper使用自定义的Python二进制文件,而不是运行一个virtualenvwrapper。为此,您需要使用virtualenv使用的VIRTUALENV_PYTHON变量:
$ export VIRTUALENV_PYTHON=/usr/bin/python3
$ mkvirtualenv -a myproject myenv
Running virtualenv with interpreter /usr/bin/python3
New python executable in myenv/bin/python3
Also creating executable in myenv/bin/python
(myenv)$ python
Python 3.2.3 (default, Oct 19 2012, 19:53:16)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
You can make virtualenvwrapper use a custom Python binary instead of the one virtualenvwrapper is run with. To do that you need to use VIRTUALENV_PYTHON variable which is utilized by virtualenv:
$ export VIRTUALENV_PYTHON=/usr/bin/python3
$ mkvirtualenv -a myproject myenv
Running virtualenv with interpreter /usr/bin/python3
New python executable in myenv/bin/python3
Also creating executable in myenv/bin/python
(myenv)$ python
Python 3.2.3 (default, Oct 19 2012, 19:53:16)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

virtualenvwrapper现在允许您指定不带路径的python可执行文件。
因此(至少在OSX上)mkvirtualenv --python=python3 nameOfEnvironment
就足够了。
virtualenvwrapper now lets you specify the python executable without the path.
So (on OSX at least)mkvirtualenv --python=python3 nameOfEnvironment
will suffice.

在Ubuntu上;使用使用mkvirtualenv -p python3 env_name
python3加载virtualenv。
在环境内部,用于python --version
验证。
On Ubuntu; using mkvirtualenv -p python3 env_name
loads the virtualenv with python3.
Inside the env, use python --version
to verify.

您可以将其添加到您的.bash_profile或类似文件中:
alias mkvirtualenv3='mkvirtualenv --python=`which python3`'
然后在要创建python 3环境时使用mkvirtualenv3
代替mkvirtualenv
。
You can add this to your .bash_profile or similar:
alias mkvirtualenv3='mkvirtualenv --python=`which python3`'
Then use mkvirtualenv3
instead of mkvirtualenv
when you want to create a python 3 environment.

我发现跑步
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
和
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenv-3.4
在Ubuntu上的命令行中,强制mkvirtualenv使用python3和virtualenv-3.4。仍然要做
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
创造环境。假设您在/ usr / bin / python3中有python3,在/usr/local/bin/virtualenv-3.4中有virtualenv-3.4。
I find that running
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
and
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenv-3.4
in the command line on Ubuntu forces mkvirtualenv to use python3 and virtualenv-3.4. One still has to do
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
to create the environment. This is assuming that you have python3 in /usr/bin/python3 and virtualenv-3.4 in /usr/local/bin/virtualenv-3.4.

This post on the bitbucket issue tracker of virtualenvwrapper may be of interest.
It is mentioned there that most of virtualenvwrapper’s functions work with the venv virtual environments in Python 3.3.

我这样添加export VIRTUALENV_PYTHON=/usr/bin/python3
到我的~/.bashrc
:
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENV_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh
然后跑 source .bashrc
您可以为每个新环境指定python版本 mkvirtualenv --python=python2 env_name
I added export VIRTUALENV_PYTHON=/usr/bin/python3
to my ~/.bashrc
like this:
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENV_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh
then run source .bashrc
and you can specify the python version for each new env mkvirtualenv --python=python2 env_name
