我正在使用 Ruby 2.7.1、Rails 5.2、Webpacker 5.4.3。我剛剛安裝了 Stimulus 和 Webpacker 來添加一些功能。
我只使用 scss 而不是通過 webpacker。我添加 webpacker 只是為了一個單一的刺激控制器和動作。
我還將 nodejs buildpack 添加到 Heroku，它位于我的 Ruby buildpack 之上。
在本地一切正常，但是當我部署到 Heroku 時，出現以下錯誤。
我已經嘗試了大多數 SO 執行緒，包括Rails 中的所有步驟：Webpacker 4.2 can't find application in /app/public/packs/manifest.json heroku
然后在加載頁面時出現另一個錯誤：

你能提供你完整的 webpacker.yml 嗎？
也許您在默認情況下遺漏了一些東西？
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
也許這會有所幫助？

我不確定這最終是如何解決的。
我將我的 Ruby 從 2.7.1 捆綁安裝更新到 2.7.5
我有一條訊息要安裝 Graphviz，我在 gemfile 中添加了：
gem 'ruby-graphviz', '~> 1.2', '>= 1.2.3'
捆綁安裝
本地運行：
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，它起作用了。
