[FIXED] How to activate an existing virtualenv projects?

Issue

I'm a beginner to Django and Python, and I've never used virtualenv before. However, I do know the exact commands to activate and deactivate virtual environments (online search). However, this learning course takes time and sometimes I need to split the work over 2 days.

When I create a virtualenv today and do some work, I'm unable to access the same virtualenv tomorrow. Even when I navigate to that folder and type in .\venv\Scripts\activate, it says "system cannot find specific path".

How can I open already existing virtual environments and the projects within them? Could it be that I need to end my previous session in a certain way for me to access it the next time?

Solution

Even though pipenv had so many problems. I suggest you use it when you are new to virtual env.

Just

pip install pipenv
cd $your-work-directory
pipenv shell

Then you created your project env. You can active it by:

cd $your-work-directory
pipenv shell

You can install packages by:

cd $your-work-directory
pipenv install $yourpackage --skip-lock
