Heroku 產生錯誤 H10 並導致應用程序崩潰

Question

我正在使用nodejs + reactjs + express + mongodb

將我的后端部署在另一台服務器上，它的工作非常好。

但是當我訪問前端時，它顯示“H10”錯誤，當我使用heroku local運行同一個項目時，它的工作非常好。

我的 package.json

{
  "name": "ecommerce",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "braintree-web-drop-in-react": "^1.1.1",
    "concurrently": "^5.2.0",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.1",
    "react-stripe-checkout": "^2.6.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "heroku-postbuild": "npm run build"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "engines": {
    "node": "10.x",
    "npm": "6.x"
  }
}

我得到的日志：

2020-04-25T18:04:45.413902+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=ecommerce-frontend-dweep.herokuapp.com request_id=0d7f7627-3a3e-4a79-8221-b09f89fb49d0 fwd="103.240.77.140" dyno= connect= service= status=503 bytes= protocol=https

同時運行heroku run node console

Output（如果需要）：

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module '/app/console'

已經嘗試過First Heroku deploy failed `error code=H10`的解決方案，但沒有成功

對我來說同樣的問題，按照下面的步驟后它工作得很好：

首先嘗試安裝服務

npm install serve --s

然后將 package.json 中的腳本替換為：

"scripts": {
"dev": "react-scripts start",
"start": "serve -s build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"heroku-postbuild": "npm run build"
}

之后添加，提交並推送到 heroku
