ruby-on-rails - 缩短终端中的错误消息

Question

终端中的 Rails 错误消息太长并且通常包含无用的信息。是否有 gem/解决方案来缩短 rails 错误消息？ 示例:

2.2.2 :012 >   puts 1.red

我目前得到的:

NoMethodError: undefined method `red' for 1:Fixnum

我想要的:(可选红色)

NoMethodError: undefined method `red' for 1:Fixnum
===>Long error message saved in e. Get full messages with 'puts e' 

这可能吗？

Answer 1

您可以尝试 better_errors gem。 它还通过浏览器提供了对错误的更好解释。

这是 link to the github repo
