我将 Heroku 上的应用程序从带有 Webpacker 的 Rails 6 更新到带有 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，而在我的 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，所有文件都在那里，除了 application.js 和一个 css 文件。
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/ * 并在本地正常工作。在 Heroku 生产中，即使我尝试手动编译，application.js 也不会复制到public/assets/ *
我的 esbuild 脚本如下，可以正常工作：
"build": "esbuild app/javascript/*.* --bundle --outdir=app/assets/builds"
有没有人有将 application.js 加载到 public/assets 中的线索或解决方案，这样我就不会收到以下错误？
The asset "application.js" is not present in the asset pipeline
这是 app/javascript/application.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';
}
这是一个也没有编译的css文件，也许有连接，但我无法找到。（此文件夹中除此文件之外的所有其他 css 文件仅编译到公共/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放入app/assets/builds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，但这是我的部署日志。（没有错误）

更新
似乎当我部署到 Heroku 时，Heroku 首先运行资产编译，然后构建包 json。因此，编译运行时 builds 文件夹为空，并且 application.js 不会复制到 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 中的文件添加到存储库中。所以现在编译运行时，构建文件夹包含文件并将其编译到公共/资产。我知道这不是解决问题的最佳方法，但目前这是我知道的唯一解决方法。
如果有人知道一种方法来编辑 heroku 部署脚本以在包 json 构建脚本之后运行资产编译，那么它可以解决问题。
