Python 页面扩展中存在PluginNotFoundException

我正在使用CKAN作为我的开放数据门户。它是使用Python框架用Python编写的。我想集成插件。所以我用了下面的步骤

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

我仍然得到以下例外。考虑到我试图重新启动CKAN和Apache服务器

ckan.plugins.core.PluginNotFoundException: pages

但是，当我运行python setup.py develope命令时，仍然会发现插件安装正确。请参阅下面的输出

尽管它说插件安装正确，但还是发生了异常。如何修复此问题？

您已将这些软件包安装到系统Python中（/

usr/local/lib/python2.7/dist-packages

）。确保使用virtualenv中的pip和python。看起来virtualenv根本没有被激活。尝试执行

source/usr/lib/ckan/default/bin/activate

---

您还可以尝试使用virtualenv的绝对路径调用pip和python。

我尝试执行source/usr/lib/ckan/default/bin/activate，然后执行上述4个命令。仍然会发生相同的异常。
