我正在运行一个使用sunspot_rails和sunspot_solr宝石的Rails应用程序。我遇到了 org.apache.solr.common.SolrException之类的几个错误：打开新的搜索器时出错并且 RSolr :: Error :: ConnectionRefused：连接被拒绝。
系统配置
Ruby 2.2.6
Rails 4.2.2
RVM 1.29.8
java -version
java version "11.0.2" 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)
我也尝试使用Java8和Java12，但是导致了相同的错误。
宝石文件
gem 'sunspot_rails'
gem 'sunspot_solr'
gem 'sunspot_mongo'
bundle install
安装所需的宝石
rails g sunspot_rails:install
在项目目录中创建一个solr /目录，但是缺少我在其他人提到的StackOveflow其他问题中提到的bin /和data /目录
rake sunspot:solr:start
Successfully started Solr ...
我可以在localhost：8982上看到solr管理面板
rake sunspot:solr:run
~/RubymineProjects/kadium$ rake sunspot:solr:run --trace

谢谢。

这条线引起了我的注意：
733 WARN (main) [ ] o.a.s.c.SolrResourceLoader Can't find (or read) directory to add to classloader: lib (resolved as: <<YOUR PATH>>/solr/lib
1 /检查目录是否在此路径上
2 /如果目录存在，请检查您（如果您是启动Solr进程的用户）拥有该目录，并且其内容//具有读取权限
作为一个附带说明，afaik您应该避免使用用户名为互联网上的人们提供完整的路径，它为我提供了有关您的身份/工作地点的大量信息，并且使我更容易最终遭受暴力侵害你的系统。您应该编辑帖子以掩盖完整路径。
