pip install -r dev_requirements.txt not working

[fredbje]

Describe the bug I am trying to build the project from source. I cloned the repo, created a virtual environment:

python3  -m venv symforce-env  
source symforce-env/bin/activate

Then I ran pip install -r requirementst.txt, but encountered the following error:

pip install -r dev_requirements.txt

I ran pip install -r dev_requirements.txt again, and now it seems to work. I did not make any changes between the attempts.

I think it's possible this was some kind of setuptools incompatibility, and the initial pip install installed a compatible version of setuptools so that the second run succeeded? Going to close for now but if this is a recurring issue we'll do something to fix
