Question

在Homebrew的帮助下，我试图在运行OS X 10.10.3的MacBook Pro上构建一个ckan（v2.3）数据门户。虽然我不得不对官方文档进行小的调整以便从源代码中为我安装，但我已经能够使用Solr和Tomcat运行它并安装DataStore和FileStore组件而不会发生任何事件。我可以使用系统管理员帐户上传文件并再次下载，没有任何问题。

问题是当我尝试安装DataPusher以确保用户上传的数据自动放入DataStore时。遵循＆＃34;开发＆＃34;位于here的指南中的部分会导致一些非常奇怪的事情发生。

首先，虽然＆＃34; PORT＆＃34;在我的DataStore安装设置中的变量被设置为默认值（8800）并且在端口8800上没有任何阻止它，实际服务似乎坚持通过端口8000运行。我不认为这应该影响任何事情，但为了记录所有奇怪的行为，我将它留在这里。
其次，只要我将我的ckan安装的DataPusher网址指向正确的端口并在ckan的development.ini文件中启用该应用及其所有默认设置，我的ckan即时安装变得完全无法使用。首页显示正常，但每次我尝试登录或注册为任何用户我得到此追溯（道歉长度）：

它似乎与用户的使用方式有关。显示最近的活动，但在此之后我不知道发生了什么。常识似乎要求我可以禁用插件，事情会好起来，但遗憾的是情况并非如此。即使我从ini文件中的DataPusher插件断开连接并完全停止服务，此错误仍然存在。它有效地破坏了我的整个ckan安装，而我能够再次使用的唯一方法就是从源头再次安装ckan。

这是第一次发生这似乎是一个侥幸。我认为我的数据库中已经损坏了一些东西，所以我卸载了ckan，删除了所有的PostgreSQL数据库并从一个干净的平板重新安装了所有东西。同样的事情发生了。如果有人能够帮助我理解为什么会发生这种错误，更广泛地说为什么安装DataPusher会永久破坏我的ckan网站，我将非常感激。谢谢你的帮助。

所以问题似乎是使用普通的ckan文档从源代码安装导致我走错了路。他们的安装仍然安装了几个与SQLAlchemy相关的错误版本的插件。按照here的说明为我制定并消除了这次崩溃。我建议任何维护ckan源代码的人检查SQLAlchemy 0.8是否是自动安装的版本，而不是0.7.8。感谢Mikko Ohtamaa的帮助。
