Can I have multiple django projects in the same virtualenv folder
It really depends on the situation. Suppose if your Project A need to use Pip version 17.01 to run while your project B need to use Pip version 18.01 to run. So It is not possible to use 1 virtual env to run multiple project but the downside of having multiple virtual environments is it consume much space & resource of PC.
Another newbie to django here. I was wondering if it is recommended/not-recommended to run two different projects in the same virtualenv folder that have the same django version. To be more clear, is it necessary to create separate virtualenv everytime I want to start a new project when i know that i am using same django version for all projects. I am using python django on OSX.
