Question

I am working on Django project with virtualenv and connect it to local postgres database. when i run the project is says,

ImportError: No module named psycop         


        

Answer 1

They changed the packaging for psycopg2. Installing the binary version fixed this issue for me. The above answers still hold up if you want to compile the binary yourself.

See http://initd.org/psycopg/docs/news.html#what-s-new-in-psycopg-2-8.

Binary packages no longer installed by default. The ‘psycopg2-binary’ package must be used explicitly.

And http://initd.org/psycopg/docs/install.html#binary-install-from-pypi

So if you don't need to compile your own binary, use:

pip install psycopg2-binary
