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?

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

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

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。
install -U
不是卸载而是升级。该命令的输出很令人困惑,因为它突出显示了一条消息“成功卸载 foo”。 - jwg
