Python Django Pip Update Problems: How To Get Compatible Versions?

I tried to run a django demo project on a hosted server (Ubuntu 16.04): it worked fine. Then I tried to run the same code on a local machine: Unhandled exception in thread started

Solution 1:

Use a requirements file

1. on the working system, do pip freeze > requirements.txt

2. copy that file over (I always check one in as part of my repository)

3. on the new machine, probably in a virtual environment, you can update to those versions with pip install -r requirements.txt

Solution 2:

As RishiG said you should create a requirements.txt file which will contains the project dependencies but mostly you should use a virtual environnement. It will allow you to isolate your python version and packages and their version for each of your project.
