Upgrading pycharm venv python version

Question

I have python 3.6 in my venv on PyCharm. However, I want to change that to Python 3.8. I have already installed 3.8, so how do I change my venv python version?

I am on windows 10.

Changing the version on the project intepreter settings seems to run using the new venv not my existing venv with all the packages I have installed. Attempting to add a new intepreter also results in the "OK" button being greyed out, possibly due to the current venv being not empty.

Answer 1

You need to create a new virtual environment with the interpreter which version is 3.8.

1. Go to Settings => Project => Python Interpreter

2. Click on the vertical 3 dots, and click on "Add".

3. Select Virtualenv Environment => New Environment

4. Choose as base interpreter the one which version is 3.8 (the one you just installed)

5. Click on "OK" => "OK"

6. Once you have set the new interpreter, PyCharm will warn you that you need update some dependencies based on your requirements.txt file or, in this case, Pipfile.lock (I am using pipenv for this project)

That's it!
