javascript - TextEncoder 未定义。使用 nodejs 在 wsl2 上连接到 MongoDB

Question

我正在尝试让一个简单的 MERN 应用程序在 Ubuntu wsl2 实例上运行。我正在关注这个 guide .这是我在 server.js 中的代码(它与指南中的代码略有不同，因为不推荐使用 body-parser。使用此 post 中的建议我更改了这些方法)。

const express = require("express");
const mongoose = require("mongoose");

// Setup express app
const app = express();

app.use(
    express.urlencoded({
        extended: false
    })
);

app.use(express.json());

// Configure Mongo
const db = "mongodb://localhost/313-demo-mern-db";

// Connect to Mongo with Mongoose
mongoose
    .connect(
        db,
        { useNewUrlParser: true }
    )
    .then(() => console.log("Mongo connected"))
    .catch(err => console.log(err));

// Specify the Port where the backend server can be accessed and start listening on that port
const port = process.env.PORT || 5000;
app.listen(port, () => console.log(`Server up and running on port ${port}.`));

我有一个 MongoDB 数据库正在运行，它当前正在“等待端口 27017 上的连接”。我运行命令 node server.js并得到错误。

I was having the same error today. Updating the node to latest version fixed the issue for me.

You may refer https://askubuntu.com/a/480642/1267099 for updating node.

编辑:更新到最新版本(不是当前稳定版)
