ruby-on-rails - rake 太阳黑子 :solr:start throwing an error

Question

我正在尝试将 sunspot 与 Rails 4 一起使用，但遇到了一些问题。当我的 gemfile 中只有 gem 'sunspot_rails', '2.0.0' 时，我收到此错误:

Note: This task has been moved to the sunspot_solr gem. To install, start and
  stop a local Solr instance, please add sunspot_solr to your Gemfile:
  group :development do
    gem 'sunspot_solr'
 end

但是当我添加该 gem(也是 v 2.0.0)时，我收到此错误:

rake aborted!
Don't know how to build task 'sunspot:solr:start'
/home/toasty/.rvm/gems/ruby-2.0.0-p195/bin/ruby_noexec_wrapper:14:in `eval'
/home/toasty/.rvm/gems/ruby-2.0.0-p195/bin/ruby_noexec_wrapper:14:in `<main>'
(See full trace by running task with --trace)

我看到过这个问题: Sunspot/Solr raketasks not loading in Rails 3 Mountable Engine但它似乎不适用于我的情况。有人有什么想法吗？ sunspot_solr 与 Rails 4 不兼容吗？

我也遇到了同样的问题。我不记得了，但我发现你需要添加这个 rake 任务

lib/tasks/solr.rake

namespace :sunspot do
  namespace :solr do
  desc 'Start the Solr instance'
    task :start => :environment do
      case RUBY_PLATFORM
        when /w(in)?32$/, /java$/
          abort("This command is not supported on #{RUBY_PLATFORM}. " +
          "Use rake sunspot:solr:run to run Solr in the foreground.")
     end

  if defined?(Sunspot::Rails::Server)
    Sunspot::Rails::Server.new.start
  else
    Sunspot::Solr::Server.new.start
  end
  puts "Successfully started Solr ..."
end

desc 'Run the Solr instance in the foreground'
task :run => :environment do
  if defined?(Sunspot::Rails::Server)
    Sunspot::Rails::Server.new.run
  else
    Sunspot::Solr::Server.new.run
  end
end

desc 'Stop the Solr instance'
task :stop => :environment do
  case RUBY_PLATFORM
  when /w(in)?32$/, /java$/
    abort("This command is not supported on #{RUBY_PLATFORM}. " +
          "Use rake sunspot:solr:run to run Solr in the foreground.")
  end

  if defined?(Sunspot::Rails::Server)
    Sunspot::Rails::Server.new.stop
  else
    Sunspot::Solr::Server.new.stop
  end
  puts "Successfully stopped Solr ..."
end

# for backwards compatibility
task :reindex => :"sunspot:reindex"
end
end
