[英]rails 4: Errno::ENOENT (No such file or directory @ rb_sysopen - /assets/
[英]No such file or directory @ rb_sysopen when using a component with react-rails gem
我正在使用帶有 gem react-rails 的 rails 5.1.7。
我在 erb 視圖中添加了一個 react 組件:
<%= react_component("cardlist", { all_cards: @all_cards }, {prerender: true}) %>
這在我的本地環境中運行良好,但是在將應用程序部署到 heroku 時,如果我嘗試訪問包含react_component
幫助程序的 erb,我會在日志中收到以下消息:
ActionView::Template::Error (No such file or directory @ rb_sysopen - /app/public/packs/js/server_rendering-7bdf65f03078e0e44c86.js
我也嘗試添加一個 App 組件並渲染它,但它一直給出相同的消息。
我還在 heroku 上添加了一個節點 buildpack,並確保該應用程序僅使用 npm 而不是 yarn,並添加了節點版本:
"engines": {
"node": "12.18.3"
}
但我總是收到同樣的信息
ActionView::Template::Error (No such file or directory @ rb_sysopen - /app/public/packs/js/server_rendering-7bdf65f03078e0e44c86.js
如果我將 pre render 設置為 true,則組件在生產中出現,日志上沒有錯誤,但我需要通過服務器渲染來完成。
按照 Justing 的建議刪除 public/packs 中的文件並在生產環境中編譯后,我得到:

在我的本地環境中運行良好
您是否嘗試在本地預編譯?
RAILS_ENV=production NODE_ENV=production rake assets:precompile
然后運行你的 rails 應用程序
RAILS_ENV=production rails s
錯誤應該很明顯。 我的猜測是您在預編譯過程中出現了一些錯誤,因此文件js/server_rendering-7bdf65f03078e0e44c86.js
不存在。
您可能還想確保您的 /public/packs 目錄中沒有任何文件簽入您的 git 存儲庫。
