我在Heroku上更新了我的应用程序，从带Webpacker的Rails 6更新到带esbuild的Rails 7。
我在生产中收到的错误如下：

The asset "application.js" is not present in the asset pipeline

我进入我的Heroku服务器，看到application.js文件在app/assets/builds中，在我的manifest.js中，它的设置如下：

//= link_tree ../images
//= link_tree ../builds

但是当我检查**public/assets/***文件夹时，除了application.js和一个css文件外，所有文件都在那里。
正如Heroku在他们的网站上推荐的那样，我也在本地尝试了以下代码：

RAILS_ENV=production bundle exec rake assets:precompile

这会将包括application.js在内的所有文件编译到**public/assets/*中，并在本地正常工作。在Heroku生产环境中，即使我尝试手动编译，application.js也不会复制到public/assets/***中
我的esbuild脚本如下所示，运行时没有任何问题：

"build": "esbuild app/javascript/*.* --bundle --outdir=app/assets/builds"

有人有线索或解决方案将application.js加载到public/assets中，这样我就不会出现下面的错误了吗？

The asset "application.js" is not present in the asset pipeline

下面是应用程序/javascript/应用程序. js

// Entry point for the build script in your package.json
import "@hotwired/turbo-rails"
import "./controllers"
import * as bootstrap from "bootstrap"
import "lazysizes"
import "@fortawesome/fontawesome-free/js/all"

if ('scrollRestoration' in window.history) {
  window.history.scrollRestoration = 'manual';
}

这是一个css文件，也没有编译，也许有一个连接，但我不能找到。（所有其他的css文件在这个文件夹中，除了这个文件只是编译到公共/资产）
应用程序/资产/样式表/共享/swiper.scss

@import "swiper/swiper.scss";
@import "swiper/modules/navigation/navigation.scss";
@import "swiper/modules/lazy/lazy.scss";

.swiper-button-next {
  color: #000000;
}

.swiper-button-prev {
  color: #000000;
}

和我的脚本将scss到css放置到app/assets/build中的脚本

"build:css": "sass ./app/assets/stylesheets/application.bootstrap.scss:./app/assets/builds/application.css ./app/assets/stylesheets/controllers:./app/assets/builds/controllers ./app/assets/stylesheets/shared:./app/assets/builds/shared ./app/assets/stylesheets/devise:./app/assets/builds/devise ./app/assets/stylesheets/errors.scss:./app/assets/builds/errors.css --no-source-map --load-path=node_modules"

不确定是否有帮助，但这里是我的部署日志。（没有错误）

更新

当我部署到Heroku时，Heroku首先运行assets compile，然后运行包json builds。因此，当compile运行时，builds文件夹是空的，application.js没有复制到public/assets。
现在为了解决这个问题，我从git ignore中删除了builds文件夹，并将builds中的文件添加到仓库中。所以现在当编译运行时，build文件夹中有文件，并将其编译到public/assets中。我知道这不是最好的解决方法，但目前这是我所知道的唯一解决方法。
如果有人知道如何编辑heroku部署脚本来运行assets compile after package json build脚本，那么它就解决了这个问题。
