我正试图按照本教程部署一个基本的"你好，世界"使用Rails和Heroku的应用程序。
当我运行git push heroku main命令时，我会看到下面的错误消息。

我满足了Heroku教程的所有先决条件，我正在使用特定版本的ruby和Rails来匹配Learn enough Rails教程
$ ruby -v
ruby 2.7.4p191
$ rails -v
Rails 6.1.4.1
$ gem -v
3.2.31
$ Bundler -v
Bundler version 2.2.31
我已经尝试使用yarn将webpack和webpack-cli包添加到package.json文件中的依赖项中。但这无济于事。
我对编程很陌生，所以我可能会错过一些显而易见的东西。有人有什么线索吗？
谢谢！
更新：似乎问题的出现是因为我的主目录中有一个版本的yarn太新了。通过安装heroku试图在部署时运行的同一版本的yarn(v1.22.4(并将该版本用于yarn install并更新yarn.lock文件，解决了问题。
