为什么pip会显示“没有名为commands.install的模块”？

我已经安装了pip，并且在cmd中将目录移动到C:\Python27\Scripts。我尝试运行以下代码：pip install whatever.whl

底部显示一个类似Python的随机代码：

'ImportError: No module named commands.install'是什么意思？

为什么要使用这个扩展？

来自pip文档：

$ pip install SomePackage            # latest version
$ pip install SomePackage==1.0.4     # specific version
$ pip install 'SomePackage>=1.0.4'     # minimum version

请看这里：

解决所有pip问题的最佳方法是重新安装Python 2.7.9并运行它。否则，您的确切问题可能会非常难以跟踪。

我曾在另一种情况下通过卸载问题软件包解决了这个问题。你可以试试以下方法：

sudo pip install -U setuptools

这是我的日志：

sam@sam:~$ sudo pip install protobuf --upgrade
