ruby-on-rails – 为什么我在UTF-8中获得无效的字节序列

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – 为什么我在UTF-8中获得无效的字节序列前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
为什么我会收到此错误
invalid byte sequence in UTF-8

用于加载图像:

= image_tag 'features_home/show1.png'

编辑

我注意到这个问题发生在我进行捆绑更新之后,任何图像都会出现错误..我会尝试在此处添加详细信息:

我不知道哪个宝石造成了这个问题..

解决方法

这似乎是Haml用于解析image_tag指令路径的less-rails gem中的错误.

调用image_tag时,less-rails最终会尝试扫描文件所依赖的资产,但可能会无意中使用非文本文件.这会导致您遇到的错误.

项目中(有点过时的)分支上的fix exists,用于正确验证路径.我们可以参加测试:

gem 'less-rails',github: 'Metaskills/less-rails',branch: 'depends_only_on_less_files'

有关更多详细信息,请参阅this ticket.正如那里所建议的那样,您可能需要验证代码是否使用了适合图像的路径.
