如何从 python 代码激活/停用 virtualenv? [英] How to activate/deactivate a virtualenv from python code?

问题描述

对于激活，有一个脚本可以使用 execfile('C:/path/to/virtualev/Scripts/activate_this.py', dict(__file__='C:/path/to/virtualev/Scripts/activate_this.py')).但是，由于我仍然可以从当前的 python 脚本中导入不在 virtualenv 中的包，我对它的工作方式感到困惑.
对于停用，根本没有 python 脚本.
我该怎么办?

For activation there is a script that activates a virtualenv from an already running python interpeter using execfile('C:/path/to/virtualev/Scripts/activate_this.py', dict(__file__='C:/path/to/virtualev/Scripts/activate_this.py')). However since I can still import packages that are not in the virtualenv from the current python script I am confused about how it works.
For deactivation there is no python script at all.
What should I do?

您必须使用自定义 Python 解释器来安装库.但要使用库，您只需要确保路径正确.一种脚本可用于更正路径.你可以设置环境喜欢:

You must use the custom Python interpreter to install libraries. But to use libraries, you just have to be sure the path is correct. A script is available to correct the path. You can setup the environment like:

activate_this = '/path/to/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
