In my Sinatra/activerecord app, rake test gives me this odd series of warnings:
/Users/pitosalas/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/activesupport-5.1.5/lib/active_support/core_ext/hash/slice.rb:21: warning: method redefined; discarding old slice

I am mainly interested in the messages like: warning: previous definition of to_s was here
What are they telling me? I can't find any clear reference to that message on line.
答案 0 :(得分：1)
这实际上是一个两部分警告。
bunny-2.9.2 / lib / bunny / channel.rb：1580：警告：方法重新定义;丢弃旧的to_s
bunny-2.9.2 / lib / bunny / channel.rb：257：警告：to_s的先前定义在这里
它告诉您to_s为该课程定义了channel.rb:257，然后在to_s找到了同一班级channel.rb:1580的另一个定义。它通过使用channel.rb:1580处的模糊性来警告您模糊性及其解决方法。
