Ruby on Rails Solr 重新索引错误

Question

当我尝试使用 Solr 重新索引时，我收到此错误

DEPRECATION WARNING: Sprockets method `register_engine` is deprecated.

use `register_compressor` or `register_transformer`.

• 我尝试过使用 bundle exec rake 或 Straight rake 来完成此操作
• 我已经删除了solr文件并重启了
• 我已删除xml文件并重新启动

我想我几乎做了所有的事情都无济于事......

有什么建议吗？

Answer 1

对于警告消息，您可以将 sprokets 版本降级到 3.6.3

gem "sprockets", '3.6.3'

或者使用这个版本的less-rails gem：

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

Answer 2

我有一个包含这些行的 upload_image.rb

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

评论那些，让它再次工作！ 出于某种原因，这使 solr 无法重新索引！
