"pip install psycopg2" doesn't solve "Python library psycopg2 is required for PostreSQL support."

I installed psycopg2 after being prompted to by stellar, but stellar init keeps failing even after installing psycopg2. I'm on a Mac and python was installed through Anaconda.

Command Line

$ stellar init
Please enter the url for your database.

For example:
PostgreSQL: postgresql://localhost:5432/
MySQL: mysql+pymysql://root@localhost/: postgresql://localhost:5432/
Python library psycopg2 is required for PostreSQL support.
You can install it with pip:
pip install psycopg2

$ pip install psycopg2
Requirement already satisfied (use --upgrade to upgrade): psycopg2 in /Users/leonelgalan/anaconda/lib/python2.7/site-packages

$ which pip
/Users/leonelgalan/anaconda/bin/pip

$ which python
/Users/leonelgalan/anaconda/bin/python

$ stellar init
Please enter the url for your database.

For example:
PostgreSQL: postgresql://localhost:5432/
MySQL: mysql+pymysql://root@localhost/: postgresql://localhost:5432/
Python library psycopg2 is required for PostreSQL support.
You can install it with pip:
pip install psycopg2

Sorry for the "noise", just typing questions helps finding a solution:

If you are using Anaconda, like me, install psycopg2 using conda install psycopg2 rather than pip install psycopg2

I'm having the same problem, however I'm not using anaconda, but just PIP, even installed it for this purpose...

There's a known issue that the "helpful" error message hides the underlying error, try doing the following:

python -c "import psycopg2"

Had to install psycopg2 globally. Ubuntu: apt-get install python-psycopg2
