I ran: 'pip install uncertainties' and it went into Python27, but I need to run this from Python34. Now, I can't seem to uninstall it from 27. That seems to be the default and it keeps going back to that when I try to install uncertainties.

In Environment Variable I only have this in the Path: 'C:\Python34\Scripts'

I don't know why it keeps defaulting to Python27. Is there a way to change this, or control it?

I read all comments, and took a look at those other resources. Now I am editing my OP to explain my findings (I can add this to the Comments section).

I got virtualenv to install just fine. However, I still can't get any traction with this thing.

C:>pip3.4 install uncertainties 'pip3.4' is not recognized as an internal or external command, operable program or batch file.

C:>pip34 install uncertainties 'pip34' is not recognized as an internal or external command, operable program or batch file.

C:>py -3.4 -m pip install uncertainties C:\Python34\python.exe: No module named pip

C:>python3 -m pip install uncertainties 'python3' is not recognized as an internal or external command, operable program or batch file.

C:>python34 -m pip install uncertainties 'python34' is not recognized as an internal or external command, operable program or batch file.

C:>python3.4 -m pip install uncertainties 'python3.4' is not recognized as an internal or external command, operable program or batch file.

Thanks.

You need to use virtualenv. Its purpose is exactly that: keep different python interpreters and their libraries correctly installed and isolated from one another.

  • I will include python3 installation directory in path variable so `python3` commands becomes available to system. Then simply do python3 pip install – r0xette Nov 04 '16 at 15:16
