CKAN 页面扩展中的 PluginNotFoundException

Question

我正在使用CKAN作为我的开放数据门户。CKAN是用Python编写的，使用的是Pylons框架。我想要集成一个叫做ckanext-pages的插件。所以我按照下面的步骤操作。

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

但是我还是遇到了下面的错误。尽管我已经尝试重启CKAN和Apache服务器。

ckan.plugins.core.PluginNotFoundException: pages

当我运行python setup.py develop这个命令时，它还是显示这个插件安装得很正确。请看下面的输出。

尽管它说插件安装得很好，但还是出现了错误。我该怎么解决这个问题呢？

你已经把软件包安装到了系统的Python里（/usr/local/lib/python2.7/dist-packages）。确保你使用的是虚拟环境里的pip和python。看起来你的虚拟环境根本没有被激活。试着执行一下 source /usr/lib/ckan/default/bin/activate 来激活它。你也可以尝试用虚拟环境的绝对路径来调用pip和python。
