[ckan-dev] Virtualenv tips: how to reload the ini file

[Mike Sinclair]

Hi John,

Python is not going to be running by default, it has to be invoked, so I'm
wondering what happened prior to step 1 above such that python is already
running. Is it that you're trying to run paster twice, using separate
terminals? Why?

It looks like you are serving paster on one terminal and then trying to
serve again on another, leading to the conflict.

As for joining and leaving the virutalenv - the commands are:

$ . /usr/lib/ckan/default/bin/activate
$ deactivate

Cheers,
