No module named sqlalchemy

[Kiffin Gish]

While trying to setup the Bespin Python Server, I followed verbatim the instructions in the README.txt and ran 'paver create_db' but got the following error:

'ImportError: No module named sqlalchemy'

Did I miss something?

It sounds like something failed to install. If you're on a linux
system, make sure you have the python-devel package installed (on the
Mac, you'll need Xcode). If that's what you're missing, you can rerun
the bootstrap script once you've installed the needed piece.

If that's not the problem, then you'll likely have a pip-log.txt file
that will have some clues as to what went wrong at the end of the
file.

Good luck!

FYI, the package is 'python-dev' on Ubuntu

I have Ubuntu 8.10 and once I installed 'python-dev' everything worked
fine, thanks! Maybe the README.txt file needs updating?

I've updated the README for the next time I push to hg.mozilla.org.
I've highlighted
the line about installing python-dev because I think some people have missed it.

[Barttos]

yes :-) readme need it, first time i installed all modules manually

I too have tried to install the bespin python server following the
instructions in the readme.txt and after running python create_db get
the same 'ImportError: No module named sqlalchemy' except:

I am running CentOS 5 and have already installed python-devel
successfully.

In my pip-log.txt I find:

raise InstallationError(
InstallationError: Could not install requirement httplib2 (from -r
requirements.txt (line 11)) because of HTTP error HTTP Error 404: Not
Found for URL http://bitworking.org/projects/httplib2/dist/httplib2-0.4.0.tar.gz
(from http://pypi.python.org/simple/httplib2)

Does anyone have a suggestion?

Thank you

It looks like httplib2 has a broken download URL in the Python Package Index.

I've changed the requirements file to point to the real location of
httplib2 at googlecode.

Kevin, Thank you for updating the broken url. I downloaded the latest
package off the bespin release site and this is what I now get:

Bespin requires Python 2.5

The same here.

Sqlalchemy is installed 0-4-6-1
Python ins installed 2.5 (also 2.4 is present as I see from synaptic,

You need not remove Python 2.4, as long as you make sure you run
bootstrap.py with Python 2.5.

Basically, "no module named sqlalchemy" means that it didn't install
sqlalchemy and likely failed somewhere before that. Take a look at
pip-log.txt and that should help narrow down what didn't install and
why.
