Answer 1

On Windows, make sure your path includes the Postgres bin directory. In my machine it's c:\Programs\PostgreSQL\9.3\bin.

Answer 2

You can also try installing win-psycopg from here

Answer 3

Try to run the following command:

pip install psycopg2-binary

Answer 4

It is a problem with virtualenv and psycopg2. I have copied _psycopg.cp38-win_amd64.pyd from global python to \venv\Lib\site-packages\psycopg2 This worked for me.

Answer 5

According to this thread you need to install an earlier version since there were problems with the latest build.

Simply install an earlier version, (2.0.10 works great), even with PostgreSQL 8.4.x series.
