Ckan install fails with: Unknown distribution option: 'message_extractors'

Question

I am installing build CKAN in a virtual environment. I had problems installing some modules.

(default)[ckan@localhost ~]$ pip install -e git+https://github.com/ckan/[email protected]#egg=ckan
Obtaining ckan from git+https://github.com/ckan/[email protected]#egg=ckan
  Updating ./default/src/ckan clone (to ckan-2.6.0)
  Running setup.py egg_info for package ckan

Cleaning up... Command python setup.py egg_info failed with error code 1 in 
/usr/lib/ckan/default/build/funcsigs Storing complete log in 
/usr/lib/ckan/.pip/pip.log

Full pip.log

After suppose "Successfully installed ckan" should have this command (virtual env)

(default)[ckan@localhost ~]$ paster
-bash: paster: command not found

Updating setuptools solved the build problem, but I still have same warnings . — LeonanCarvalho
The warning about 'message_extractors' is nothing to worry about. — D Read

It is complaining about the setuptools version only being 0.9.8 when funcsigs wants setuptools 17.1 or newer.

I'm not clear where this is specified in funcsigs, indeed I just installed it ok with setuptools version 2.2, so I'm not sure what's going on here. Maybe the log is misleading and something else is requiring a newer version of setuptools. Anyway, CKAN is perfectly happy with the latest setuptools version, so just do upgrade it.

Simplest way to try upgrading setuptools is:

pip install -U setuptools
