Question

我已经搜索了几个小时来解决这个问题而无济于事。我似乎无法解决这个问题。

* cap production deploy *会抛出以下错误，如日志中所示。这solution无济于事。

我耐心等待解决方案

Answer 1

正在编译的一个JS文件包含无效的UTF-8字节。我不知道哪一个，但我建议你调试的方法是在本地编辑/var/www/html/app/shared/bundle/ruby/2.2.0/gems/json-1.8.3/lib/json/common.rb:223:in generate'的等效路径，将破解调用包装在一个块中：

begin
  # Whatever normally goes here.
rescue JSON::GeneratorError
  puts whateverliststhefilename
end

如果您已经在使用此功能，那么您也可以放入binding.pry而不是放置。

知道文件名后，通过UTF-8验证器运行它，就像你在链接的SO答案中看到的那样，并修复它。如果JS在gem中，请尝试将gem恢复到原始状态。如果JS在您的项目中，请相应地修复它。

您可以使用http://guides.rubygems.org/command-reference/#gem-pristine恢复已修改或损坏的gem。完成后，请务必从gem文件中删除调试代码。

这更像是一个教导如何捕鱼答案而不是“这是什么错误以及如何解决它”的答案。对此感到抱歉，但我们无法做到这一点，除非它是宝石中一个众所周知的问题，Google搜索会提出这个问题，或者我们有完整的源代码。

希望这有帮助！
