我现在在我的软件的后端，它通过电子运行，但我不能得到数据，所以我试图从一个python程序检索数据，它使用Flask发送它，但当我运行npm start命令时，它给我以下错误消息：

Module not found: Error: Can't resolve 'child_process' in 'C:\Users\cantr\Desktop\Stage ingénieur KOMILFO SPORT\Sail Vision\React\react-electron\src\pages'

下面是我的Javascript和python脚本：
联森：

import React from "react";

class Home extends React.Component {
    constructor() {
        super();
        this.hello = require("child_process").spawn("python", ["./hello.py"]);
        this.state = { fs_s5: 12 };
        this.hello.stdout.on('data', (data) => {
          this.setState({ fs_s5: data });
        });
    }
    render(){
        return(

            </div>

        );
    }
}

export default Home;

巨蟒：

from __future__ import print_function
import time
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World! This is powered by Python backend."

if __name__ == "__main__":
   print(12)
   time.sleep(5)
   app.run(host='127.0.0.1', port=5000)

此致，
