How to solve this “ python setup.py egg_info” Problems on Pycharm?

When I run the cmd on Pycharm terminal>> pip install django-heroku ; it gives this error

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-dtad1xv7/psycopg2/

After that again I,m trying to install psycopg2 by pip install psycopg2 / conda install psycopg2; it again gives this error

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-9r48hwpd/psycopg2/

I am now totally confused about what should I do now?
