Package.json：

 { "name": "backend", "version": "1.0.0", "engines": { "node": "14.16.1" }, "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "nodemon src/server.json" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "cors": "^2.8.5", "crypto-js": "^4.0.0", "express": "^4.17.1", "mongoose": "^5.12.3", "node-fetch": "^2.6.1" }, "devDependencies": { "nodemon": "^2.0.7" } }

檔案：

 web: npm start

在 server.js 的末尾，我有：

 app.listen(process.env.PORT || 3333);

這是一種可行的解決方案。 如果有，請告訴我。 您似乎有一個節點應用程序，但在 Procfile 中您通常不會給出命令 npm start。 您給出起始 javascript 文件。

嘗試類似：

Procfile: web app.js 
// Whatever is the name of your main javascript file name.
