ruby-on-rails - 开始时 slim-rails gem 粉碎 `register_config_processor' : wrong number of arguments

Question

当我将 slim-rails 添加到 Gemfile 并启动我的应用程序时，它崩溃并出现以下错误:

/Users/rado/.rbenv/versions/2.3.1/gemsets/project/gems/sprockets-4.0.0.beta2/lib/sprockets/processing.rb:211:in `register_config_processor': wrong number of arguments (given 4, expected 2..3) (ArgumentError)
  from /Users/rado/.rbenv/versions/2.3.1/gemsets/project/gems/sprockets-4.0.0.beta2/lib/sprockets/processing.rb:53:in `register_preprocessor'

  from /Users/rado/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/sprockets-rails-3.1.1/lib/sprockets/railtie.rb:178:in `block in build_environment'
  from /Users/rado/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/sprockets-rails-3.1.1/lib/sprockets/railtie.rb:177:in `each'

我的rails 版本是5.0.0.1有人知道如何解决这个问题吗？

Answer 1

如果 gem 直接从 GitHub 插入则工作:

gem 'slim-rails', github: 'slim-template/slim-rails'

已解决的问题:gem 'slim-rails' 与 Sprockets 4 不兼容。(如果您使用的是 Rails 5 而不是 Sprockets 3，此解决方案可能无济于事。)

slim-rails 团队已经在 this commit 中解决了这个问题, 但对我来说，当我从 rubygems.org 插入 gem 时它仍然崩溃— 但在使用 GitHub 版本时效果很好。
