弃用警告:不推荐使用 alias_method_chain [英] DEPRECATION WARNING: alias_method_chain is deprecated

问题描述

我将项目升级到 Rails 5.当我运行 rspec 时，我收到警告

I upgraded the project to Rails 5. When I run rspec I get a warning

DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. 
From module, you can access the original method using super. 
(called from <top (required)> at /home/alex/projects/myproject/config/application.rb:13)

application.rb 中的失败行是:

The failing line in application.rb is:

Bundler.require(*Rails.groups)

如何找出导致此弃用警告的原因以及如何消除错误?

How do I find out what is causing this deprecation warning and how to get rid of the error?

推荐答案

安装(除非已经安装)ack并在终端中运行:

Install (unless already installed) ack and run in the terminal:

ack alias_method_chain /Users/username/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.1/gems/

它将指示使用 alias_method_chain 的所有位置(文件和代码行).

It will indicate all places where alias_method_chain is used (files and code lines).

99% 的几率在您的一些宝石中使用它.

99% chance it is used in some of your gems.
