我正在使用 Ruby 2.7.1、Rails 5.2、Webpacker 5.4.3。我刚刚安装了 Stimulus 和 Webpacker 以添加一些功能。
我只使用 scss，而不是通过 webpacker。我添加 webpacker 的目的只是一个刺激控制器和动作。
我还将 Nodejs 构建包添加到 Heroku，并将其放置在我的 Ruby 构建包之上。
在本地一切正常，但是当我部署到 Heroku 时，出现以下错误。
我已经尝试了大多数SO线程，包括Rails：Webpacker 4.2无法在/app/public/packs/manifest.json heroku中找到应用程序中的所有步骤
然后我在加载页面时遇到另一个错误：
ActionView::Template::Error (Webpacker can't find application.js in /app/public/packs/manifest.json. Possible causes:

您能提供完整的 webpacker.yml 吗？
也许你在默认设置中遗漏了一些东西？
default: &default
source_path: app/javascript
source_entry_path: packs
public_root_path: public
public_output_path: packs
cache_path: tmp/cache/webpacker
check_yarn_integrity: false
webpack_compile_output: true
也许这会有帮助？
我不确定这个问题最终是如何解决的。
我将 Ruby 从 2.7.1 更新到了 2.7.5 捆绑安装
我收到一条安装 Graphviz 的消息，我在 gemfile 中添加了：
gem 'ruby-graphviz', '~> 1.2', '>= 1.2.3'
捆绑安装
本地运行：
rake assets:precompile
添加到 gemfile.lock
PLATFORMS
x86_64-darwin-21 //this existed
x86_64-linux //this was added
推送到 Heroku 并且成功了。
通过
npmnpm installyarnyarn install使用 Rails 版本
6.1.6我在 Rails 6 中遇到过这个问题，发现这个解决方案有效：
npm install --save-dev @babel/plugin-proposal-private-methods
npm install --save-dev @babel/plugin-proposal-private-property-in-object
rm package-lock.json # `rm` aliases to move it to the trash
yarn
这是 Rails 6.1.7.6、node v16.13.1、ruby 2.7.1p83
我在 High Sierra 的旧 MacBook 上运行，无法运行任何示例 Rails 7 应用程序。
