我尝试在本地预编译但在本地执行此操作时出错是不同的。见下图。
error while performing rake assets:compile
我该怎么办？我一直在寻找解决方案已经有一段时间了，我找不到具体问题。
我的application.css文件包含* = require bootstrappl，所以我删除了以检查它是否可以正常工作。现在我能够在本地预编译资产，但仍然无法部署heroku遇到相同的错误。
JSON :: GenerateError：源序列非法/格式错误utf-8
请帮忙。
如果您需要我的任何代码，请告诉我。

尝试在Rakefile中设置字符编码以纠正一个put：
#encoding: cp1250
在你的Rakefile之上。 （将cp1250替换为您的编码）。 并阅读有关该主题的内容。
