Question

我在Express项目中有一个React应用。 Express项目的“ dev”脚本设置为启动Express项目和React应用程序。一切在本地都可以正常运行，但是当我上传所有内容时（我正在使用A2托管，并通过this article安装了node和npm）并运行dev脚本，它只是说这两个都在启动，但挂死了，从没有经过npm info lifecycle nrdesign@0.1.1~start: nrdesign~0.1.0。无论如何，我决定尝试运行React应用程序，因为我拥有Express项目的唯一原因是针对Nodemailer，并且它无法启动脚本，并打印了以下日志。我对日志一无所知，想知道是否能得到一些帮助。抱歉，长帖子：P。我将在下面添加index.js，package.json和日志。

文件夹结构：

Express
  |___app.js
  |___package.json (express)
  |___client
    |___index.js
    |___package.json (react)

Express app.js：

var createError = require("http-errors");
var express = require("express");
var path = require("path");
var cookieParser = require("cookie-parser");
var logger = require("morgan");

var indexRouter = require("./routes/index");

var app = express();

// view engine setup
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "jade");

app.use(logger("dev"));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));

app.use("/", indexRouter);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get("env") === "development" ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render("error");
});

app.listen(40001);

module.exports = app;

反应index.js：

import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import "./animate.min.css";
import "./wing.css";
import App from "./App.js";
import * as serviceWorker from "./serviceWorker";
ReactDOM.render(<App />, document.getElementById("root"));
serviceWorker.unregister();

Express package.json：

{
  "name": "react-backend",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www",
    "dev": "(cd client && npm run start) && npm run start"

    "jade": "~1.11.0",
    "morgan": "~1.9.1",
    "npm-run-all": "^4.1.5"
  }
}

反应package.json：

{
  "name": "nrdesign",
  "version": "0.1.0",
  "private": true,
  "proxy": "http://localhost:40001",

    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}
