我不明白为什么active_support 试图将赛璐珞作为依赖。

【问题讨论】：

使用带有 RVM 的 MAC 添加
应用块代码格式改进，让问题更清晰
不是 ActiveSupport 需要赛璐珞。查看堆栈跟踪这一行似乎是问题的根源。from /Users/siva/.rvm/gems/ruby-2.2.3/gems/pubnub-3.8.0/lib/pubnub.rb:6您正在使用 PubNub gem？它确实对赛璐珞有依赖性。 github.com/pubnub/ruby/blob/master/pubnub.gemspec

标签： ruby-on-rails rubygems activesupport celluloid

【解决方案1】：

将pubnub 添加到您的Gemfile 后，您是否添加了bundle install？

看起来pubnub 依赖于celluloid，这需要pubnub-3.8.0/lib/pubnub.rb:6 的第6 行上的celluloid/current。

如果您执行bundle install，它会确保正确安装Gemfile 中定义的所有gems 及其依赖项。

请参阅pubnub 了解更多信息。
