无法在python 3.4和2.7的pip之间切换[Windows]

Question

I have python 3.4 installed on my windows for a while but now I need to get 2.7 to work another project. I downloaded the 2.7.10 package from the official python and installed it. Everything was fine until I tried to install packages using pip.

What I have read in different places is that pip-2.7 should work but the command is not recognized. If I get get-pip.py to try to install pip using py get-pip.py it tells me it's already installed.

So is there anyway to get this working?

Answer 1

Taken from the docs

py -2 -m pip install SomePackage # default Python 2

py -2.7 -m pip install SomePackage # specifically Python 2.7

py -3 -m pip install SomePackage # default Python 3

py -3.4 -m pip install SomePackage # specifically Python 3.4

So in your case you'll need either of the two:

py -2   -m pip install SomePackage  # default Python 2
py -2.7 -m pip install SomePackage  # specifically Python 2.7
