在使用python 3创建虚拟环境时，如何解决看似无止境的循环？

Question

Cmd prompt says Running virtualenv with interpreter c:\\users\\di203179\\appdata\\local\\programs\\python\\python37-32\\python.exe repeatedly and never creates virtual environment.

I've tried upgrading pip and python, and running variations of the command virtualenv mypython

virtualenv mypython

I expect a folder with the name following the command virtualenv to be created.

But the actual result is this:

Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe

Until i hit ctrl-c which gives this:

Answer 1

Proably you're using the version 16.6.1 of the virtualenv module which causes that bug, try using the following code to install 16.6.0:

 pip install virtualenv==16.6.0

Then try to create the virtual enviroment again.

Answer 2

Out of virtualenv update to version 16.0.2. Try: pip install virtualenv --upgrade
