Question

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'

修改

我注意到此问题仅在我bundle update之后发生，任何图片都会出现错误..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..

这似乎是Haml用于解析less-rails指令路径的image_tag 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。我们可以参与测试：

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

有关详细信息，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当的图像路径。

为什么我在UTF-8中得到无效的字节序列
