Resolve command "python setup.py egg_info" failed with error code 1 bumpy Road

Machine: OS X

Local want to run the next open source Django Blog app, down the source into the PIP Install-r requirements.txt

Result repeated error, Command "python setup.py egg_info" failed with error code 1

Tried many times to keep this error in the last line.

I started thinking about permissions, setuptools issues.

Later, there is a turnaround, I put requirements.txt inside one after the installation, the last is PSYCOPG2 this installation has a problem

Pip I wronged you, but the official source for the watercress after the download speed of the leverage, from then on I abandoned PyPI source.

Back to the problem, PSYCOPG2 is PostgreSQL's Python interface, the reason for the error is very simple, that is, I will first install PostgreSQL database.
