我正在开发一个使用 MongoDB 的 Ruby on Rails 应用程序，并且我已经实现了基本的 Sunspot 功能。这是有关我的环境的一些信息

  • 导轨 3.2.11
  • 蒙戈 2.4.3
  • 太阳黑子 2.0.0
  • 宝石 mongo_mapper
  • 宝石 sunspot_rails
  • 宝石太阳黑子_solr
  • 宝石 sunspot_mongo_mapper

我以前一切正常，但现在我遇到了问题。我可以成功运行

bundle exec rake sunspot:solr:start

但是当我尝试

bundle exec rake db:seed

我收到以下错误：

rake aborted!

如果我尝试具有相同的 java.lang.NullPointerException 堆栈跟踪但 Ruby 堆栈跟踪略有不同， 我也会得到类似的错误。bundle exec rake sunspot:reindex

更新

对不起，我很久没有解决这个问题了。我终于尝试删除我的solr/目录，然后重新启动。我现在可以运行bundle exec rake sunspot:solr:start，然后bundle exec rake db:seed没有任何问题，但是当我尝试时仍然出现错误：

bundle exec rake sunspot:solr:reindex

我看到以下堆栈跟踪

$ bundle exec rake sunspot:solr:reindex

那么有谁知道这个问题是什么？

任何对此问题的见解将不胜感激！谢谢！

我也遇到了这个错误 - https://stackoverflow.com/a/17665820/227403

解决方案是我的 solr 目录在 SVN 部署中出现。我删除了目录并重新启动它。

我有同样的错误，只是它被触发了bundle exec rake sunspot:solr:reindex，有帮助的是强制退出我能找到的所有 java 进程。在我重新启动 SOLR 之后

bundle exec rake sunspot:solr:start

然后我可以重新索引而不会出现任何错误。

您应该尝试使用 Pry & prey-debugger 来单步执行最后一个文件，看看发生了什么。

/home/my_username/.rvm/gems/ruby-1.9.3-p429/gems/mongo_mapper-0.12.0/lib/mongo_mapper/plugins/dynamic_querying.rb:39:in `method_missing'

它正在寻找不再存在的东西。也许您在 Searchable 中定义了一个已删除或更改的字段？

你的 solr/ 目录结构是什么，它应该看起来像：

sole/
  conf/
  data/
  pids/

我的本地机器有这 3 个文件夹，它可以工作。但是我的两台服务器都没有 conf/. 一个有效，另一个无效。

一开始我尝试删除整个 solr/ 文件夹，然后重新启动 solr，问题仍然存在，然后我重新安装 java，重新安装 gems，问题仍然存在。

最后我在本地机器上添加了一些由solr自动创建的配置文件的conf/，我将它们推送到服务器，解决了问题。

我花了一整天的时间，希望这个答案有帮助。
