Sometimes we need to invoke different versions of Python packages and modules in our program, so we can use Virtualenv's virtual environment to help us isolate them, so let's take a look at installing Windows with virtualenv to create a standalone Python environment 0. When will the virtualenv be used?Suppose that the two applications in the system, where a application to the library Libfoo version requirements of 1, and B application to the same lib
