由于"404 Not Found"错误,sunspot_rails无法索引

我正在尝试在一个小的Rails应用程序中安装Sunspot,完全遵循gem设置说明,但每当RSolr::Error::Http: RSolr::Error::Http - 404 Not Found我尝试索引数据时遇到错误.我可以用一个新的应用程序重现这个; 以下是我遵循的确切步骤:

创建一个新的Rails 4.2.5应用程序:

$ rails new test_sunspot
$ cd test_sunspot/
$ spring stop # spring can cause `generate` commands to hang
$ rails g model Thing title:string
$ rake db:migrate
$ rails c
  > Thing.create!(title: "Cats")
  > Thing.create!(title: "Pizza")
  > exit

向模型添加太阳黑子索引:

class Thing < ActiveRecord::Base
  searchable do
    text :title
  end
end

将Sunspot添加到Gemfile:

...
gem 'sunspot_rails', '2.2.2'
gem 'sunspot_solr',  '2.2.2'  
...

安装,启动和重新编制太阳黑子:

$ bundle install
$ rails g sunspot_rails:install # default sunspot.yml is not changed
$ ps aux | grep solr # confirm that no Solr services are running
$ bundle exec rake sunspot:solr:start # generates solr/ dir; no errors
$ bundle exec rake sunspot:solr:reindex

此reindex命令产生以下输出.当我进入Rails控制台并尝试创建一个新的Thing对象时,它会触发相同的错误(因为Sunspot尝试更新索引):

ps aux | grep solr(在启动Solr之后)的输出:注意,提到的PID solr/pids/development/sunspot-solr-development.pid是62449,它匹配第三行:

我在Mac OSX优胜美地

我已经卸载并重新安装了相关的宝石,尝试降级到Sunspot 1.3.0,甚至跑了gem pristine --all,结果没有变化

编辑:我已阅读太阳黑子/ Solr 404 Not Found错误的其他类似门票.看起来这些情况下的解决方案相当于"重置"Solr配置并且与新的(开发环境)项目无关:在运行rake sunspot之前没有先前的Solr实例正在运行:solr:start; 这是一个完全新鲜的Rails项目,所以solr /目录只是新生成的; 这是在发展,而不是生产; 并加入solr_home: solr到sunspot.yml或更新path: /solr/default对404结果没有影响.

问题:

知道为什么会这样吗？

这种破坏可能是由于我的OSX环境中安装错误造成的吗？我该怎么看？

您是否可以按照相同的步骤在新安装的当前Rails上使Sunspot正常工作？

提前致谢!
