通过Homebrew与python2和python3一起使用virtualenv [英] virtualenv with python2 and python3 via Homebrew

问题描述

我已经用Homebrew安装了python2和python3.我想使用virtualenv，但不确定是否需要为python2/python3安装它.我也想知道是否可以使用virtualenvwrapper来根据自己的需要将VIRTUALENVWRAPPER_PYTHON设置为python2或python3?

I have installed python2 and python3 with Homebrew. I would like to use virtualenv but I am not sure if I need to install it for both python2/python3. I am also wondering if I use virtualenvwrapper can I just set the VIRTUALENVWRAPPER_PYTHON to be either python2 or python3 depending on my needs?

任何帮助将不胜感激.

Any help is greatly appreciated.

谢谢， 格雷格

推荐答案

根据此问题，对于两个版本，您都可以使用单个virtualenv，只需使用-p path/to/python/version或--python=path/to/version标志来指定用于创建虚拟环境的版本.请注意，您可以对mkvirtualenv使用相同的标志.

According to this SO question, you could use a single virtualenv for both version, just use the -p path/to/python/version or --python=path/to/version flag to specify which version to use for the creation of the virtual environment. Note that you can use the same flag with mkvirtualenv.

此帖子建议仅使用系统Python(在您的情况下为2.7)自行安装virtualenv.

This post recommends to just use the system Python (2.7 in your case) to install virtualenv itself.
