如何检查virtualenv是否使用'--no-site-packages'创建？ [英] How to check whether virtualenv was created with '--no-site-packages'?

问题描述

有时候我会收到错误，我怀疑是我的Django应用程序的结果，使用全球安装的Python模块/ Django应用程序，而不是其virtualenv中的那些。

Sometimes I get errors that I suspect are the result of my Django app using globally installed Python modules/Django apps instead of those within its virtualenv.

有没有方法来检查我的应用程序的virtualenv是否使用'--no-site-packages'创建，而无需删除它，然后重新创建它如下？

Is there a way to check whether my app's virtualenv was created with '--no-site-packages' without having to delete it, then re-create it as follows?

deactivate
rmvirtualenv my_env
mkvirtualenv my_env --no-site-packages
workon my_env
pip install -r requirements.txt

当然必须有更好的方法！谢谢。

Surely there must be a better way! Thanks.

推荐答案

在< env> /lib/pythonX.X / code>当您使用创建虚拟环境时，调用 no-global-site-packages.txt - no-site-packages 。

There's a file in <env>/lib/pythonX.X/ called no-global-site-packages.txt when you create a virtual environment with --no-site-packages.

只需使用virtualenv 1.7：

Just tried this with virtualenv 1.7:

% virtualenv --no-site-packages env.without
% virtualenv --system-site-packages env.with

% find env.without | sed 's/env.without//' > files.without
% find env.with | sed 's/env.with//' > files.with

% diff files.with*
230a231
> /lib/python3.2/no-global-site-packages.txt
