Command "python setup.py egg_info" failed with error code 1 in PATH/psycopg2

I needed to upgrade PostgreSQL from version 9.5 to version 11. After that, when I recreated my virtualEnv from a 'requirements.txt' file, I started giving the following error when installing the psycopg2 package:

Collecting psycopg2 == 2.6.2 (from -r conf/requirements.txt (line 50))

After some research, I ran the following commands to try to solve, but it did not work:

sudo apt-get install postgresql-server-dev-all
sudo apt-get install postgresql-common

Finally, I noticed that version 2.6.2 of psycopg2 only supports version 9.5 of postgresql. For 11 you should use the latest version of psycopg2, that is, version 2.7.7. After you change the requirements.txt file, and the virtualEnv has been recreated correctly.

I hope it will be useful to others.
