我已经安装了pip，并将我的目录在cmd中移动到C：\ Python27 \ Scripts。 我试试这个代码：' pip install whatever.whl '
它说在随机代码的底部（看起来像Python）：
' ImportError: No module named commands.install '发生了什么事？
我在另一种情况下通过卸载违规软件包解决了这个问题。 你可以尝试：
sudo pip install -U setuptools
这是我的日志：

所有pip问题的最佳解决方案是你新安装python 2.7.9然后运行它。 否则，你确切的问题可能很难追查。
你为什么使用扩展名？
从pip文档：
$ pip install SomePackage # latest version $ pip install SomePackage==1.0.4 # specific version $ pip install 'SomePackage>=1.0.4' # minimum version
