按照本教程virtualenv我收到此消息：
C:\Users\Dev\Desktop>mkvirtualenv AndroidKivy
C:\Users\Dev\Envs is not a directory, creating
Running virtualenv with interpreter C:/Python27/python.exe

我读了这个mkvirtualenv results in error: The system cannot find the path specified并使用命令where python.exe。我的PATH中只有一个python.exe运行时，所以起初我的问题不适合它。
C:\Python27\python.exe
再一次，找到了这个主题Stackoverflow。即使像这样mkvirtualenv -p C:/Python27/python.exe AndroidKivy执行，我也会收到同样的错误。
