我为此失去了所有的头发：

我的 Rails 服务器启动正常，但无论向它发出哪个请求（资产和公共内容除外），我都会收到此错误：

ArgumentError in HomeController#index

invalid byte sequence in US-ASCII

我的团队在 Windows 上工作，并且在他们的平台上运行良好，但是该错误发生在我的 ubuntu 计算机上。到目前为止一切正常，如果我回滚到我的最新提交，它会再次工作，所以错误在合并中。

问题是：

  • 我该如何调试这个问题，因为它不是很冗长？
  • 错误实际上意味着什么？Ascii 是预期的，这不是我们所拥有的，或者 ascii 是被发现的，这不是预期的？
  • 错误更可能出现在应用程序控制器中的 gem 中吗？
  • 有没有办法过滤所有特殊字符以了解它的来源？
  • 还有什么其他信息可以帮助我调试这个？

git log所以，git diff <commit_hash> <previous_commit_hash>我最终通过检查历史中的每个提交（

我在助手中有非 ASCII 字符（显然在每次调用时加载）：

  def group_currency(group)
    currency = group.currency
    case currency 
    when 'EUR'
      haml_tag "€"
    when 'USD'  
      haml_tag "$"
    when 'GBP'
      haml_tag "£"   
    end

  end

因此，在文件开头添加它可以解决它：

#encoding: utf-8
module GroupsHelper
...

但是我发现更多的疑问是为什么 Rails 不能在日志中找到并报告出现问题的文件......我为此在 Rails 上创建了一个问题：https ://github.com/rails/rails/issues/ 12041
