Rails 中的 YAML 解析问题

Question

我在 Elastic Beanstalk 部署上有一个问题：

YAML syntax error occurred while parsing /var/app/ondeck/config/database.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Error: (<unknown>): found character that cannot start any token while scanning for the next token at line 2 column 1 /var/app/ondeck/config/environment.rb:5:in `<top (required)>' /opt/rubies/ruby-2.4.2/bin/bundle:23:in `load' /opt/rubies/ruby-2.4.2/bin/bundle:23:in `<main>'

Caused by: Psych::SyntaxError: (<unknown>): found character that cannot start any token while scanning for the next token at line 2 column 1 /var/app/ondeck/config/environment.rb:5:in `<top (required)>' /opt/rubies/ruby-2.4.2/bin/bundle:23:in `load' /opt/rubies/ruby-2.4.2/bin/bundle:23:in `<main>' Tasks: TOP => environment (See full trace by running task with --trace).

正如我所读到的，这是因为 YAML 禁止使用制表符，而是使用空格。

问题是我手动检查了每个 YAML 文件的选项卡，但从未找到。我想我错过了一些东西所以我的问题是：是否有任何脚本可以遍历我的整个源代码，在每个 YAML 文件中用 2 个空格替换制表符？

毕竟它是 ruby​​：编写脚本比在 SO 和谷歌上提问更容易、更快捷。

Dir['*/**/*.yml'].each do |f| 
  File.write(f, File.read(f).gsub(/\t/, '  '))
end
