I18n::InvalidLocaleData: I18n gem 在 js 导出中存在问题答案

【问题标题】：I18n::InvalidLocaleData: I18n gem has issues in js exportI18n::InvalidLocaleData: I18n gem 在 js 导出中存在问题
【发布时间】：2018-12-26 07:22:12
【问题描述】：

我正在 OS X 10.13.4 上使用 Rails 3.2.22.4、Ruby 2.2.7 开发一个应用程序。有多个翻译文件，例如。 en.yml, sq.yml 基于国家。从下面的 rubymine 执行命令时，在加载网页时会出现错误。

rake --trace i18n:js:export

en.yml 中的 yaml 内容已经过验证并且是正确的。从文件中删除后引发错误的特定行将在其他一些 .yml 文件中给出错误。正在使用当前版本的 gem i18n (0.9.5)。
Rails 服务器启动，但加载 Web 应用程序的第一页时因相同错误而中断。
代码遇到 i18n 翻译代码时抛出错误，yml 格式不是问题，因为错误会从一个文件移动到另一个文件。
这主要是 i18n、Psych 等的 gem 问题，但更改多个版本无济于事。

尝试加载页面时在浏览器中显示错误：

can not load translations from /Users/biju/projecty/config/locales/en.yml: 
#<Psych::SyntaxError: (/Users/biju/projecty/config/locales/en.yml): found unknown escape character while parsing a quoted scalar at line 26 column 27>

尝试执行 rake 任务时出现错误堆栈

经过足够的搜索后，我无法获得指针，但不确定可能是宝石问题。任何帮助表示赞赏。

【问题讨论】：

可以分享一下yaml文件吗
我已经评论了该行，下一次执行 i18n 命令在其他文件中出现错误
如果没有您的 yml 文件，我们如何提供帮助？请提供该文件或描述如何重建此错误。
.yml 文件应该不是问题，原因是如果我评论错误移动到另一个 .yml 的行。同样的 yml 文件也在不同的设置上工作。
很好，但是如何重建这个错误呢？现在看起来像“我认为I18n 不是必须的。请告诉我为什么？”。您必须检查哪些 gem、版本、配置文件会引发错误。如果你不想提供en.yml，只留下几行，模仿解析错误。

【解决方案1】：

这是一个特定于操作系统的问题，与 YAML 库有关。 .yml 文件的解析在 can_not_be_blank: "can't be blank or click on \'Any\'"处中断。以下错误仅出现在在多个 OS x 版本中测试的 OSX 中。

require 'yaml

2.4.1 :002 > trans1 = YAML.load(File.read("/Users/app.yml"))
Psych::SyntaxError: (<unknown>): found unknown escape character while parsing a quoted scalar at line 23 column 27

相同的代码在 windows irb 中工作。但是在 OSX 中，将 \'Any\' 更改为 'Any' 有助于执行操作。除了库安装在 unix vs windows 中之外，不知道可能是什么原因。
