ruby-on-rails - 无法在Rails应用中使用黑子/solr重新编制索引-错误: Severe errors in solr configuration

Question

好的，所以我有一个简单的Rails应用程序，现在我正在尝试实现黑子的搜索功能。但是，在用rails g sunspot_rails:install生成配置文件之后，在启动服务器后，它在我的rails app-dir中创建了solr-dir，然后运行bundle exec rake sunspot:solr:reindex我得到以下跟踪:

cakism@saraswati:~/railscode/calendar$ bundle exec rake sunspot:solr:reindex --trace
** Invoke sunspot:solr:reindex (first_time)
** Invoke sunspot:reindex (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:reindex

RSolr::Error::Http - 500 Internal Server Error
Error: Severe errors in solr configuration.

Check your log files for more detailed information on what may be wrong.

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

我对此特别好奇:

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

为什么会说空？与我有相同问题的其他帖子已经指定了solr/conf/solrconfig.xml，而且，当我将其更改为false时，也没有发生任何其他事情。

如果我从模型中删除了可搜索的块，那么我不会收到任何错误(但是我想那是因为它当时并没有尝试执行任何操作)

我已经通过XML验证器运行配置文件，它说它的开始标记名称不好，为2 <-1 5 <-2 6 <90％。
但是，即使我删除了给出有效XML的行，重新启动solr，并尝试重新建立索引，我仍然会遇到相同的错误。

我在这里开始感到绝望，因此任何帮助都深表感谢!

我遇到了一个非常相似的问题，并通过以下方式解决了该问题

停止所有正在运行的solr进程

删除solr文件夹

关闭/重新启动计算机

gem卸载所有相关的 gem

捆绑安装

start solr

重新索引solr
