Question

我正在尝试将 Node.js 应用程序部署到 Heroku，但出现错误找不到模块“express”。我在这里看到了其他问题，但没有一个答案对我有用。

我的 package.json 文件：

    "@zoomus/websdk": "^1.7.8",
    "body-parser": "^1.19.0",
    "cors": "^2.8.5",
    "dotenv": "^8.2.0",
    "ejs": "^3.1.3",
    "express": "*",
    "express-fileupload": "^1.2.0",
    "jquery": "^3.5.1",
    "lodash": "^4.17.20",
    "morgan": "^1.10.0",
    "pg": "^7.18.2",
    "postgres-migrations": "^4.0.3",
    "react": "16.8.6",
    "react-dom": "16.8.6",
    "react-redux": "7.1.0",
    "redux": "3.7.2",
    "redux-thunk": "2.2.0",
    "socket.io": "^2.3.0",
    "webpack": "^4.43.0",
    "webpack-cli": "^3.1.2",
    "webpack-dev-middleware": "^3.7.2",
    "webpack-dev-server": "^3.11.0"
  }
