Rails UTF-8 中的无效字节序列（ArgumentError）

Question

我所做的只是从从服务器下载的代码中rails s，该代码运行没有问题，但是很顽固地克服了这个错误

rails s
=> Booting Thin
=> Rails 4.0.2 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Exiting
/usr/share/rvm/gems/ruby-2.1.4/gems/rack-1.5.2/lib/rack/builder.rb:36:in `[]': invalid byte sequence in UTF-8 (ArgumentError)

    from bin/rails:4:in `require'
    from bin/rails:4:in `<main>'

任何一点帮助对我来说都是一个救命的小窍门，用无数的安装和配置敲了我几天的头。

提前致谢。

在您的 gemfile 中使用 gem 'rack-utf8_sanitizer' 或 gem "handle_invalid_percent_encoding_requests" 并运行 bundle。
