RVM,Ruby 1.9.2,Rails 2.3.8,Passenger和"US-ASCII中的无效字节序列"

Question

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"脚本/服务器"(或"rails服务器")和1.9.2运行,但只有Rails 3.0.0 RC应用程序可以与Passenger一起使用.Rails 2.3.8应用程序给出的错误消息是:

US-ASCII中的无效字节序列

我猜这是一个乘客问题.我使用此处的RVM指南安装了Passenger 2.2.15 .任何想法如何解决这个错误？谢谢.我已更新为包含堆栈跟踪:

Answer 1

尝试添加

# encoding: UTF-8

在main_controller.rb文件的顶部.如果可行,则在源文件中处理非US ASCII字符.

在Ruby 1.9中,我们处理三种编码上下文:

• 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的编码相同.但是,可以指定要使用的编码.例如:打开(mydata.txt,"r:UTF-8").
• 内部编码:指定从文件读取后文本数据的编码方式.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关于编码的精彩文章.

Answer 2

我在Ubuntu(11.10)上有类似的问题,因为这是在我的/ etc/apache2/envvars中:

## The locale used by some modules like mod_dav
export LANG=C
## Uncomment the following line to use the system default locale instead:
#. /etc/default/locale

将注释交换到这一个以使用/ etc/default/locale(包含LANG="en_US.UTF-8")解决了我的问题,而无需为我的ruby创建一个包装器.
