Ruby on Rails的Solr的重新索引錯誤

Question

當我嘗試使用Solr重新索引，我得到這個錯誤

DEPRECATION WARNING: Sprockets method `register_engine` is deprecated. 
Please register a mime type using `register_mime_type` then 
use `register_compressor` or `register_transformer`.

• 我試圖與束EXEC耙，或直耙做
• 我刪除了Solr的文件並重新啓動
• 我刪除了XML文件，並重新啓動

我想我差不多已經盡了一切與無濟於事...

有什麼建議嗎？

Answer 1

我有一個upload_image.rb其中有那些線

#include Sprockets::Helpers::RailsHelper 
    #include Sprockets::Helpers::IsolatedHelper 

評論者淘汰，使它重新工作！由於某種原因，這是從reindexing保持索爾 ！

Answer 2

而對於警告消息，您也可以降級sprokets版本3.6.3

gem "sprockets", '3.6.3'

或使用此版本不太軌寶石：

gem 'less-rails', git: 'https://github.com/MustafaZain/less-rails'
