连接到ckanext-showcase的CKAN中的Site-packages错误

Question

我已经安装了一个CKAN实例，并且已经安装了ckanext-showcase模块。尽管安装没有引起任何错误，并且当我设置为showcase管理员的一些用户开始添加showcase时，我能够添加一些showcase，但该模块已经停止工作。

The page {portal.url/showcase} can't be viewed unless I am connected as system administrator. When a user or even a showcase user tries to enter the page get's an internal server error.

From that point on when I am trying to create a new system administrator from console with the paster command (http://docs.ckan.org/en/latest/maintaining/getting-started.html#create-admin-user) I get the bellow message
Traceback (most recent call last):
File "/usr/lib/ckan/default/lib/python2.7/site.py", line 703, in
main()
File "/usr/lib/ckan/default/lib/python2.7/site.py", line 683, in main
paths_in_sys = addsitepackages(paths_in_sys)
File "/usr/lib/ckan/default/lib/python2.7/site.py", line 282, in addsitepackages
addsitedir(sitedir, known_paths)
File "/usr/lib/ckan/default/lib/python2.7/site.py", line 204, in addsitedir
addpackage(sitedir, name, known_paths)
File "/usr/lib/ckan/default/lib/python2.7/site.py", line 173, in addpackage
exec(line)
File "", line 1, in
KeyError: 'ckanext'

因为我现在没有能力再次安装CKAN，有什么建议可以解决这个问题吗？

任何帮助都将不胜感激

在查看我的服务器错误日志后，我发现错误不是由插件ckanext-showcase引起的，而是由模块ckanext-datarequest引起的。我的问题的第一部分与服务器错误有关，该错误来自于在1.0.2版本的插件中未处理的401未经授权的异常。当我升级到最新的1.0.3版本时，这个错误就被修复了。
