Heroku网站:启动脚本失败

Question

我来接这个

在sequelize@1.0.0启动脚本时失败。

当部署一个快递+反应应用程序。我认为heroku和concurrently有问题。

​

​

我做错什么了？我引用了this，但是这个解决方案与这个应用程序有点无关。

也引用了这个

修正了，我没有反应。

这就是我从

https://medium.freecodecamp.org/how-to-deploy-a-react-app-with-an-express-server-on-heroku-32244fe5a250

现在，在将项目推送到Heroku存储库之前，我们需要确保项目中有一个构建文件夹。将下面的脚本添加到您的package.json文件中--博客的作者

因此，我在客户端目录上进行了npm运行构建。

然后将我的package.json更改为

{
  "name": "sequelize-demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "client-install": "npm install --prefix client",
    "build": "concurrently \"cd client && npm run build\" \"npm build \"",
    "test": "echo \"Error: no test specified\" && exit 1",
    "client": "cd ./client && npm start ",
    "server-prod": "node app.js",
    "server": "nodemon app.js",
    "start": "node app.js",
    "start:dev": "concurrently --kill-others  \"npm run client\" \"npm run server\" ",
    "heroku-postbuild":"NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "async": "^2.6.1",
    "bcrypt": "^3.0.2",
    "body-parser": "^1.18.3",
    "concurrently": "^4.1.0",
    "cookie-parser": "^1.4.3",
    "cookie-session": "^2.0.0-beta.3",
    "cors": "^2.8.5",
    "crypto": "^1.0.1",
    "dotenv": "^7.0.0",
    "express": "^4.16.4",
    "express-flash": "0.0.2",
    "express-session": "^1.15.6",
    "foreman": "^3.0.1",
    "jsonwebtoken": "^8.4.0",
    "morgan": "^1.9.1",
    "nodemailer": "^5.1.1",
    "nodemon": "^1.18.9",
    "passport": "^0.4.0",
    "passport-github": "^1.1.0",
    "passport-github2": "^0.1.11",
    "passport-jwt": "^4.0.0",
    "passport-local": "^1.0.0",
    "pg": "7.9.0",
    "pg-hstore": "^2.3.2",
    "sequelize": "^4.42.0",
    "sequelize-cli": "^5.4.0"
  },
  "devDependencies": {
    "chai": "^4.2.0",
    "mocha": "^6.1.2"
  }
}

将此添加到app.js中

app.use(express.static(path.join(__dirname, 'client/build')));

if(process.env.NODE_ENV === 'production') {
  app.use(express.static(path.join(__dirname, 'client/build')));
  //
  app.get('*', (req, res) => {
    res.sendfile(path.join(__dirname = 'client/build/index.html'));
  })
}
//build mode
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname+'/client/public/index.html'));
})
