[root@edb~]$ pip3 install psycopg2
Defaulting to user installation because normal site-packages is not writeable
Collecting psycopg2

error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [1 lines of output]
ERROR: Can not execute `setup.py` since setuptools is not available in the build environment.
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.

[root@edb~]$ pip3 install --upgrade setuptools [root@edb~]$ pip3 install psycopg2
