Node.js 如何解决；无法获取/quot；AWS部署错误？

我的应用程序在Heroku上部署时运行良好。当我把它推到AWS elastic beanstalk时，它会给我一个页面，上面写着

无法获取/

日志如下所示：

-------------------------------------
/var/log/nodejs/nodejs.log
-------------------------------------

> react-express-starter@0.1.0 dev /var/app/current
> run-p server start

sh: run-p: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn

npm ERR! errno ENOENT
npm ERR! react-express-starter@0.1.0 dev: `run-p server start`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the react-express-starter@0.1.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Express server is running on localhost:8081

var express = require('express');
var app = express();

// respond with "hello world" when a GET request is made to the homepage
app.get('/', function(req, res) {
  res.send('hello world');
});

这些都会打印10次左右

package.json

  "name": "react-express-starter",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
   ...

  }
}

我尝试将我的脚本更改为

npm run dev

，因为这是我在本地启动它的方式，但这给了我

502坏网关

错误。

我看到的是，您没有定义路由“/”的响应。 您可以这样做：

-------------------------------------
/var/log/nodejs/nodejs.log
-------------------------------------

> run-p server start

sh: run-p: command not found

});

问题是，当您将它推到elastic beanstalk上时，它默认会转到根站点。也许您可以重定向到其他路径以避免这种行为。

是的，这是可行的，我想要发送的响应是一个用

React

编写的组件。当我需要该组件并试图将其发回时，它会告诉我，

无法在模块之外使用import语句。

。我可以查看您的完整代码吗？也许通过github？一旦你拿到了，让我知道。我会在这里删除我的回购协议。我得到了链接。我没有找到您重新查询组件并发送的位置。我应该看到什么文件？请查看服务器文件夹，然后index.js您真正的错误是

run-p:command not found

。我不知道run-p是什么，但看起来您需要安装它。@Jordanm我可以用什么替换它？替换是什么意思？安装工具它给了我一个页面，上面写着

无法获取/

当我从/video/token请求一些东西时，它会给我令牌。这是意料之中的。但只有主页没有显示出来。
