解决方案

根据错误提示，找到 app/models/attachement.rb 文件，确保 URI.parse 前使用 URI.escape 转义。

修改前代码

def external_url     url = URI.parse file.download_url # returns a path if local     url if url.host   end

修改后代码

def external_url     escaped_url = URI.escape file.download_url     url = URI.parse escaped_url # returns a path if local      url if url.host   end
