unable to use pip for installing python packages

Question

I have just installed python 3.4, including pip, on a win64 machine.
When trying to use pip to install a package, I encounter a strange error.
I'm running:

pip install packagename  

and get:

 Can't locate pip.pm in @INC...   

This looks like a perl error to me. I do have perl installed on my machine, but why is windows trying to invoke perl?
Waiting for your advice,
Thanks!

Answer 1

I think you have installed pip perl module , and it added the pip perl tool in your PATH variable (in upper place than pip from python). So, if you don't use that perl module, you can delete it, or call the python pip tool with the complete path

Answer 2

OK, so what did it for me was changing the name of the pip file found somewhere on my drive to pip_pm. This convinced windows to just use the python pip command. Thanks for your help anyway.
