I'm attempting to make a website with a few others for the first time, and have run into a weird error when trying to use Django/Python/VirtualEnv. I've found solutions to this problem for other operating systems, such as Ubuntu, but can't find any good solutions for Mac.
This is the relevant code being run:
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
After running that block, I get the following errors:
AssertionError
Failed building wheel for django-toolbelt Running setup.py bdist_wheel for psycopg2
...
AssertionError
Failed building wheel for psycopg2 Failed to build django-toolbelt psycopg2
I believe I've installed the "django-toolbelt" and "psycopg2", so I'm not sure why it would be failing.
The only difference I can think of is that I did not use the command
sudo apt-get install libpq-dev
as was instructed for Ubuntu usage as I believe that installing postgresql with brew took care of the header.
Thanks for any help or insight!
I had the same problem on Arch linux. I think that it's not an OS dependant problem. Anyway, I fixed this by finding the outdated packages and updating then.
pip uninstall psycopg2
pip list --outdated
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
hope this helps...
