Ruby 正则表达式错误:不兼容的编码正则表达式匹配(ASCII-8BIT 正则表达式与 UTF-8 字符串) [英] Ruby Regex Error: incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string)

问题描述

我收到两个错误，都与编码有关，而且都相关.

I'm getting two errors, both revolving around encoding and both related.

我在启动 WEBrick 时遇到的第一个错误(技术上是警告):

The first error (technically, a warning) I get when starting up WEBrick:

/Users/USERNAME/example/config/initializers/bb-ruby.rb:54: warning: invalid Unicode Property P: /:-?P/

它所指的那一行是:/:-?P/,

它只是一点正则表达式，最终是这个块的一部分:

It's just a bit of regex, ultimately part of this block:

@@tags['Razzing'] = [
  /:-?P/,
  '<img src="/assets/emoticons/razzing.png">',
  'Razzing',
  ':P',
  :razzing]

然后，我在解析某些字符串时也遇到以下错误(大概是由于同一行)...

Then, I also get the following error when parsing some strings (presumably due to this same line)...

Encoding::CompatibilityError
incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string)

我正在运行 Ruby 1.9.2 和 Rails 3.2.1.

推荐答案

您的正则表达式正在编译"为 ASCII-8BIT.

Your Regex is being "compiled" as ASCII-8BIT.

只需在声明 Regex 的文件顶部添加编码声明:

Just add the encoding declaration at the top of the file where the Regex is declared:

# encoding: utf-8

你已经完成了.现在，当 Ruby 解析您的代码时，它会假设您使用的每个文字(正则表达式、字符串等)都以 UTF-8 编码指定.

And you're done. Now, when Ruby is parsing your code, it will assume every literal you use (Regex, String, etc) is specified in UTF-8 encoding.

更新: UTF-8 现在是 Ruby 2.0 及更高版本的默认编码.

UPDATE: UTF-8 is now the default encoding for Ruby 2.0 and beyond.
