我正试图在Heroku上部署一个MERN应用程序，但在成功构建之后出现了一些错误

始终为：无法fin模块“xxx”

我的应用程序分为两个文件夹：服务器文件夹（API节点）和客户端文件夹（REACT）

根文件夹中的My package.json:

...

    "start": "cd ./server && node server.js",
    "heroku-postbuild": "cd ./client && yarn && yarn build"
  },

服务器文件夹中的My server.js文件：

  },

// Serve static files from the React app
app.use(express.static(path.join(__dirname, '../client/build')));

app.use(

);

app.use(

});

$ git push heroku master

我已经试过了：

...
"scripts": {
    "start": "cd ./server && node server.js",
    "heroku-postbuild": "cd ./client && yarn && yarn build"
  },
...

web: cd ./server && node server.js

const express = require('express');
const app = express();
const PORT = process.env.PORT || 5000;
const bodyParser = require('body-parser');
const cors = require('cors');
const mongoose = require('mongoose');
const passport = require('passport');
const users = require('./routes/api/users');
const favs = require('./routes/api/favs');
const path = require('path');
require('dotenv').config();

// Serve static files from the React app
app.use(express.static(path.join(__dirname, '../client/build')));

app.use(
    bodyParser.urlencoded({
        extended: true
    })
);

app.use(
    cors(),
    bodyParser.json()
);


mongoose.connect(
    `mongodb+srv://admin:${process.env.DB_PASS}@cluster0.o5plw.mongodb.net/${process.env.DB_NAME}?retryWrites=true&w=majority`,
    {   useNewUrlParser: true,
        useUnifiedTopology: true 
    }
    ).then(() => console.log("MongoDB connected"))
    .catch((err) => console.log("MongoDB :", err));

app.use(passport.initialize());
require('./config/passport')(passport);
app.use("/api/users", users);
app.use("/api", favs);

app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname+'/client/build/index.html'));
});

app.listen(PORT, () => {
    console.log(`Listenning on ${PORT}`);
});

$ heroku config:set NODE_MODULES_CACHE=false
$ git commit -am 'disable_node_modules_cache' --allow-empty

有人会知道吗
