Pip says old version is installed after installing new version

Question

I uninstalled pip and reinstalled it from get-pip.py , yet it reports the wrong version.

C:\>python get-pip.py
Collecting pip
  Cache entry deserialization failed, entry ignored
  Using cached pip-8.1.1-py2.py3-none-any.whl
Installing collected packages: pip
Successfully installed pip-8.1.1

C:\>pause
Press any key to continue . . .
PS C:\> pip --version
pip 6.0.3 from c:\python33\lib (python 3.3)

Has the correct version been installed? Every time I use pip it still tells me to upgrade.

Answer 1

删除c:\\python33\\lib\\pip解决了这个问题。
