python - 为什么python会挂在virtualenv中？

问题描述

我在 Windows 机器上的 Cygwin 终端中使用 virtualenv。当我没有激活 virtualenv 时，我可以运行$ python启动 python shell。我也可以$ python my_script.py在 virtualenv 中通过 fine 运行脚本，但是一旦我尝试直接在虚拟环境中启动 python shell，它就会无限期挂起。

$ virtualenv --version
15.2.0

$ python --version
Python 2.7.13

$ which python
/usr/bin/python

(virtualenv) $ python --version
Python 2.7.9

(virtualenv) $ which python
/path/to/virtualenv/dir/Scripts/python

(virtualenv) $ python -v

这一切在我看来都很正常。有任何想法吗？

解决方案

好的，我想我找到了一种解决方法，基于其他人发布然后删除的评论。

(virtualenv) $ python -m idlelib.idle

打开一个 IDLE shell，这符合我的目的。
