Ruby on rails 抛出的normalize_yaml_输入中存在无效字节序列错误？

当我试图将我的项目推送到Heroku时，出现了错误（如下）。谷歌搜索发现一些人出现了类似的问题，但错误发生前的最后一块宝石是另一块宝石，所以我认为这与典狱长无关。我发现的一些类似的错误/github问题的解决方案都指向rubygems错误，这显然是（我已经知道了，所以我怀疑这是否是问题所在）

任何建议都将不胜感激——我肯定我错过了一些简单的建议

Rubygems版本：

cobychapple at shiva in ~/code/zzz on master
± gem -v
1.8.10

---

我也遇到了同样的问题，并通过将其放在我的

Gemfile

上解决了这个问题：

if RUBY_VERSION =~ /1.9/
  Encoding.default_external = Encoding::UTF_8
  Encoding.default_internal = Encoding::UTF_8
end

---

如本文所述。

当我使用jekyll在GitHub（Ruby193）上编写静态博客页面时，遇到了一个问题：

液体错误：不兼容的字符编码：UTF-8和ASCII-8BIT

---

我通过将Ruby从Ruby 193更改为Ruby187解决了这个问题。

也为capistrano部署环境工作过（不仅仅是heroku）

if RUBY_VERSION =~ /1.9/
  Encoding.default_external = Encoding::UTF_8
  Encoding.default_internal = Encoding::UTF_8
end
