Troubleshooting

How come no module named abc?

If you’re getting something like “ImportError: No module named abc”, you probably don’t have all the required packages installed. Try:

pip install -r requirements/project.txt

No module named psycopg2

If you’re getting something like “ImproperlyConfigured: Error loading psycopg2 module: No module named psycopg2” while accessing the website, you need to install the psycopg2 module. It has recently been added to requirements/project.txt (the line that says “psycopg2==2.4”). Try:

pip install -r requirements/project.txt

If you’re getting an error like “Error: pg_config executable not found.” while installing the module, you need the PostgreSQL development package. On Ubuntu, do:

sudo apt-get install libpq-dev

ImportError related to launchpad.py

Sometimes this shows up as “Caught ImportError while rendering: cannot import name ScalarValue”.

You’re having Launchpad/bzr installation problems. Most likely cause is your C compiler. On Windows, make sure you have MinGW installed as per the installation instructions. On Linux, make sure you have the python-dev and gcc packages.

I can’t get it to work in buildout!

We don’t support buildout. See the faq.

bz2 not found

Install the appropriate systemwide package. For example, on Ubuntu do:

sudo apt-get install libbz2-dev
