Sunspot_solr gem连接问题

Question

我正在运行一个使用sunspot_rails和sunspot_solr宝石的rails应用程序。我面临着几个错误，比如org.apache.solr.common.SolrException:错误打开新的搜索程序和RSolr:: Error ::ConnectionRefused: Connection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)

我也尝试过使用Java8和Java12，但是它导致了同样的错误。

Gemfile

gem 'sunspot_rails'
gem 'sunspot_solr'
gem 'sunspot_mongo'

启动solr并运行应用程序的命令。

bundle install

安装所需的宝石。

rails g sunspot_rails:install

在项目目录中创建solr/目录，但缺少了bin/和数据/目录，我看到其他人提到了StackOveflow上的其他问题

rake sunspot:solr:start
Successfully started Solr ...

我可以在localhost上看到solr管理面板:8982。

rake sunspot:solr:run

~/RubymineProjects/kadium$ rake sunspot:solr:run --trace

我已经尝试了我在类似问题上找到的大多数解决方案，但没有一个对我有用。会很感激你能解决这个问题。

谢谢。

这句话引起了我的注意：

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/检查此路径上是否存在目录

2/如果目录存在，请检查您(如果您是启动Solr进程的用户)拥有该目录及其内容//是否具有读取权限

顺便提一句，afaik你应该避免给互联网上的人提供你的用户名的完整路径，它给了我很多关于你是谁/你在哪里工作的信息，同时也让我更容易最终强暴你的系统。你应该编辑你的帖子来掩盖完整的路径。
