问题
I'm using CKAN as my open data portal. It's written in Python using Pylons framework. I want to integrate ckanext-pages plugin. So I used below steps.
1. . /usr/lib/ckan/default/bin/activate
2. pip install -e 'git+https://github.com/ckan/ckanext-pages.git#egg=ckanext-pages'
3. cd /usr/lib/ckan/default/src/ckanext-pages
4. python setup.py develop
Still I get below exception. Given that I tried restart CKAN and Apache server.
ckan.plugins.core.PluginNotFoundException: pages
But when I run the python setup.py develop command it still that plugin is install correctly. Please see the output below.
running develop

Even though it says that plugin is installed correctly, exception is occurred. How can I fix this?
回答1:
You have installed the packages into the system Python (/usr/local/lib/python2.7/dist-packages). Make sure that you use the pip and python from the virtualenv. It seems that the virtualenv is not activated at all. Try executing source /usr/lib/ckan/default/bin/activate
You could also try to call pip and python with the absolute path of the virtualenv.
