使用 Next JS

Question

我是 Next Js 的新手。我目前安装了 supervisor 来监视文件的变化，因为 nodemon 似乎不能正常工作。它有时起作用，有时不起作用。当它工作时，我总是必须在运行 npm run dev 之前运行 npm install。

当它不起作用时，这就是我得到的

当它工作时，在我运行 npm install 之后

这是我的 package.json

{
  "name": "my-project",
  "version": "0.1.0",
  "private": false,
  "scripts": {
    "dev": "supervisor server.js",
    "start": "cross-env NODE_ENV=production supervisor server.js",
    "build": "next build"
  },

  },
  "devDependencies": {
    "cross-env": "^7.0.3",
    "supervisor": "^0.12.0"
  }
}

这是我的 server.js 文件

const express = require("express");
const app = express();
const server = require("http").Server(app);
const next = require("next");
const dev = process.env.NODE_ENV !== "production";
const nextApp = next({ dev });
const handle = nextApp.getRequestHandler();
require("dotenv").config({ path: "./config.env" });
const connectDb = require("./utilsServer/connectDb");
connectDb();
app.use(express.json());
const PORT = process.env.PORT || 3000;

console.log('starting up ++++')
nextApp.prepare().then(() => {
    app.use("/api/signup", require("./api/signup"));
    app.use("/api/auth", require("./api/auth"));
    app.all("*", (req, res) => handle(req, res));

    server.listen(PORT, err => {
        if (err) throw err;
        console.log(`express app detect changes, Express server running on ${PORT}`);
    });
});

请指教，谢谢。 编辑：我还在根目录中放置了一个 api 文件夹，不确定这是否对这个问题有任何影响。
