Question

我的ruby脚本中的第三行

# encoding: utf-8

require "mail"

导致以下错误

请注意，此错误仅发生在使用Ruby 1.9.3的AWS上生成。在使用Ruby 2进行开发时，它可以正常工作。

Answer 1

很抱歉，这不是解决方案，只是解释为什么它与ruby 2.0的工作正确但不能与1.9.3一起解决：</ p>

由于ruby 2.0所有脚本都是utf-8编码的（除非定义了其他内容）

什么是Ruby 2.0.0

[...]

语言核心功能

[...]


UTF-8默认编码，可以省略许多神奇的评论

来源：https://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/

在Ruby 1.9中，UTF-8不是默认设置，因此UTF-8中的脚本与您调用的脚本之间可能存在编码差异。

Answer 2

我解决了这个问题，将其添加到我的gemfile中：

gem 'oj'
gem 'oj_mimic_json'

然后运行bundle install并尝试再次运行服务器

需要宝石时不兼容的编码
