The Virtualenvwrapper-win of python--virtual environment

1 Problem description

When M projects require n versions of the Python Environment Configuration (m>n), we don't need to create a virtual environment for each project, just create n virtual environments. This reduces the amount of work (especially when m is much larger than N). But how do you create these n environments and manage those environments?

Through the three-party package Virtualenvwrapper-win to solve. Virtualenvwrapper-win is a toolkit based on virtualenv development. It can be scattered in various paths under the virtual environment, centralized to the unified path to manage, convenient for each virtual environment switch.
