如何在没有root用户访问权限的计算机上安装virtualenv

Question

我想在没有root特权的Linux机器上安装virtualenv。我在nettuts（http://net.tutsplus.com/tutorials/python-tutorials/python-power-tools-virtualenv/）上看到了截屏，并尝试按照以下步骤进行操作，但遇到以下错误。任何帮助表示赞赏。/home/x01010/python/virtualenv-1.9.1 > which python/opt/xpyv/bin/python/home/x01010/python/virtualenv-1.9.1 > python virtualenv.py fooPYTHONHOME is set.

Answer 1

创建虚拟环境后，您必须激活它。

virtualenv --no-site-packages </path/to/new/environment>

source </path/to/new/environment>/bin/activate  

只需在激活虚拟环境后尝试即可。
