I've tried to manually install only the psycopg2 module. As well as with a pip3 install -r requirements.txt. If anybody has encountered this error before, please provide appreciated guidance!
ERROR: Failed building wheel for psycopg2

回答1:
gcc cannot use -lssl flag by default so you should install openssl
brew install openssl
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
or install precompiled binary
pip install psycopg2-binary
