报错，看了文件路径是没问题的。代码如下：
const http = require('http');
const fs = require('fs');

http.createServer(function (request, response) {

  if (request.url == '/favicon.ico') {
    response.writeHead(200)
    response.end()
    return;
  }

  response.writeHead(200)
  fs.createReadStream(__dirname + '/index.html').pipe(response)
}).listen(3000)
