Ruby on rails 太阳黑子Solr核心初始化失败

当我运行测试时，大多数测试都会失败，并出现以下错误

Failure/Error: let(:user){ FactoryGirl.create(:user) }
   RSolr::Error::Http:
     RSolr::Error::Http - 500 Internal Server Error

那没用。查看开发管理页面：我没有看到任何警告或错误

当我转到测试管理页面时：

在测试管理站点的日志中，我看到：

我还重新启动了我的电脑。然而，它仍然不起作用。有没有关于如何解决这个问题的建议？谢谢

系统信息：

• Mac OS X 10.11 El Capitan
• 太阳黑子2.2.0
• ruby 2.2.2
• 轨道4.2.1
• solr 4.10.2

我将solr版本从sunspot附带的默认版本升级到4.10.2，以匹配我的生产环境。这似乎是把一切搞砸的行为

------部分解决方法------------

在我的

solr/conf/solrconfig.xml中，我添加了以下内容：

<lockType>simple</lockType>

无论何时关闭或启动solr实例。这似乎解决了目前的问题。我还是不明白出了什么问题
 这方面有更新吗？我也有同样的问题，我不想使用锁类型。不幸的是，我从未得到最终的解决方案。我最终选择了Elasticsearch，它更简单、更容易使用。使用Elasticsearch的searchkick gem非常棒：
