Ruby on rails Rails预编译资产失败-Errno:：EROFS:只读文件系统@dir\u s\u mkdir-/Assets

我无法将我的应用程序部署到heroku。我得到了一个EROFS错误，这显然意味着ActionPackGem试图写入只读的资产？只是猜测而已。我不知道该怎么办

以下是Heroku的日志，其中显示了错误：

您是否在

config/application.rb

中更改了

config.serve\u static\u assets=true

RAILS_ENV=production使用此命令运行。这很有效，Mohammad，谢谢。所以从现在起，我将预编译资产，而不是让Heroku做。是的，从下次开始做。请接受答案。您是否在
