我什么都不明白，这是怎么回事？我该如何解决？

这是我的后端索引，我正在使用 node、express 和 mongoDB

import express from "express";
import mongoose from "mongoose";
import cors from "cors";
import dotenv from "dotenv";

import rooms from "./routes/rooms.js";
import user from "./routes/user.js";
import tasks from "./routes/tasks.js";

dotenv.config();

const PORT = process.env.PORT || 5000;

const app = express();

app.use(express.json({ limit: "20mb", extended: true }));
app.use(express.urlencoded({ limit: "20mb", extended: true }));

app.use(cors());

app.use("/rooms", rooms);

app.use("/tasks", tasks);

app.use("/user", user);

app.get("/", (req, res) => {
  res.send("");
});

mongoose.connect(process.env.MONGODB, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  dbName: "Daily-App"
});

mongoose.set("useFindAndModify", false);

app.listen(PORT, () => {
  console.log("Server Working Succesfully");
});

如果您知道发生了什么，我很想阅读您的回答，感谢您的时间社区！

Answer 1

将节点版本添加到您的 package.json："engines": { "node": "v15.10.0" }
将“启动”脚本从“nodemon server.js”更改为“node server.js”。如果您想在本地使用 nodemone，请再添加一个脚本，例如："dev": "nodemon server.js" 和 use npm run dev 以在本地启动服务器。
您还必须将 .env 推送到您的 heroku 服务器。检查您的 .env 文件是否在 .gitignore 中被忽略。

ps：package.json：我在你的“依赖项”中没有看到“nodemon”。
你安装了吗？如果你安装了它，它应该像："nodemon": "^2.0.7" 或者如果你用 npm i --save-dev 安装它："devDependencies": { "nodemon": "^2.0.7" }
希望这对您有所帮助。
