"Failed building wheel for psycopg2" - MacOSX using virtualenv and pip
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 Anyway, I fixed this by finding the outdated packages and updating then.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 psycopg2pip list --outdatedpip install --upgrade wheelpip install --upgrade setuptoolspip install psycopg2hope this helps...
I was also getting same error. Using Python 3.7.3 and pip 19.1.1.
I used following command.
pip install psycopg2-binary==2.8.3
For MacOS users
After trying all the above methods (which did not work for me on MacOS 10.14), that one worked :
- Install openssl with
brew install opensslif you don't have it already. - add openssl path to
LIBRARY_PATH:
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/- install psycopg2 with pip
pip3 install psycopg2
