Visual Studio PyTools Create Virtual Environment Fail

Question

I am trying to create a Virtual Environment using PyTools for Visual Studio 2013. I've manually installed Python before installing Visual Studio 2013 and PyTools, and it functions correctly.

When I try to create a virtual environment through PyTools I get the following error:

AssertionError: Filename c:\\Python27\\Lib\\os.py does not start with any of these prefixes: ['C:\\Python27']

C:\\Python27 and C:\\Python27\\Lib are in my PYTHONPATH.

Answer 1

The assert error was caused because maybe you don't have a PYTHONPATH environment variable setup.

The socket error was caused because there is no included the PythonXX\\DLLs folder.

The full PYTHONPATH environment variable should look follows:

PYTHONPATH=C:\\Python27;C:\\Python27\\Lib;C:\\Python27\\DLLs
