我试图遵循这个很好的指南 http://www.tylerbutler.com/2012/05/28/how-to-install-python-pip-and-virtualenv-on-windows-with-powershell/
但是在尝试安装 virtualenv 时出现以下错误
PS C:\> pip install virtualenv
The term 'pip' is not recognized as the name of a cmdlet, function, script file
, or operable program. Check the spelling of the name, or if a path was include
d, verify that the path is correct and try again.
At line:1 char:4
+ pip <<<< install virtualenv
+ CategoryInfo : ObjectNotFound: (pip:String) [], CommandNotFound
Exception

我通常是 mac 用户,所以我了解如何使用 pip,但不知道为什么这不起作用。对powershell不太好。
