我不确定我何时开始收到此消息，但错误消息仅出现在我的开发服务器上。生产 heroku 服务器不报告任何内容。

不确定您为什么要尝试读取资产目录。但是您在开发服务器上看不到 /assets 的原因是 rails 将在开发模式下为 /app/assets/stylesheets 提供资产，用于存在的项目，但由于没有通往 /assets 的路线（通过检查rake routes）你得到一个错误。

生产rake assets:precompile中是在您上传到 heroku 期间执行的，因此会创建并填充目录 /public/assets。

你可以rake assets:precompile在你的开发机器上看看会发生什么。
