然而在一个 rails 项目中，我们已经使用了一段时间的 ok:

$ rake db:create

$ rake db:migrate
rake aborted!

$

$ cat config/initializers/configatron.rb 
require 'configatron'
Configatron::Rails.init

Answer 1

尝试暂时删除 configatron.rb 文件，看看是否有帮助。错误在第 2 行，所以这就是问题所在。

如果没有看到文件很难确定，但我会尝试永久修复它:

1. 将 require 'configatron' 添加到 app.rb
2. 更改行，使其显示 Configatron::Integrations::Rails.init 而不是 Configatron::Rails.init。
