RVM、Ruby 1.9.2、Rails 2.3.8、Passenger 和“US-ASCII 中的无效字节序列" [英] RVM, Ruby 1.9.2, Rails 2.3.8, Passenger and "invalid byte sequence in US-ASCII"
问题描述
我刚刚开始从 Ruby 1.8.7 升级到 Ruby 1.9.2(使用 RVM).我的所有应用程序都使用带有 1.9.2 的脚本/服务器"(或rails 服务器")运行，但是，只有 Rails 3.0.0 RC 应用程序可以与乘客一起使用.Rails 2.3.8 应用程序给出的错误信息是:
I just started the upgrade process from Ruby 1.8.7 to Ruby 1.9.2 (using RVM). I have all my applications running using 'script/server' (or 'rails server') with 1.9.2, however, only Rails 3.0.0 RC applications work with Passenger. The error message given by Rails 2.3.8 applications is:
US-ASCII 中的无效字节序列
invalid byte sequence in US-ASCII
我猜这是一个乘客问题.我使用 here 的 RVM 指南安装了Passenger 2.2.15.任何想法如何修复这个错误?谢谢.我已更新以包含堆栈跟踪:
I'm guessing that this is a Passenger issue. I installed Passenger 2.2.15 using the RVM guide found here. Any ideas how to fix this bug? Thanks. I've updated to include a stack trace:

推荐答案
尝试添加
# encoding: UTF-8在 main_controller.rb 文件的顶部.如果可行，则说明您正在处理源文件中的非美国 ASCII 字符.
at the top of your main_controller.rb file. If that works, you're dealing with a non US ASCII character in your source file.
在 Ruby 1.9 中，我们处理三种编码上下文:
In Ruby 1.9, we're dealing with three encoding contexts:
- 源代码编码:默认情况下，源文件中的字符串被解释为 US-ASCII，除非我在上面列出的魔术注释存在.
- 外部编码:假定文本文件中的字符与环境具有相同的编码.但是，可以指定要使用的编码.例如:open(mydata.txt, "r:UTF-8").
- 内部编码:指定从文件中读取文本数据后如何编码.默认情况下这是 nil，这意味着它将与用于读取它的编码相同.如果需要不同的东西，可以在 IO.open 中指定.例如: open(mydata.txt, 'r:UTF-8:UTF-16LE')
有关更多信息，我会阅读James Edward Gray II 撰写的关于编码的精彩文章.
For more info, I'd read James Edward Gray II's great articles on encoding.
