http请求静态文件返回使用gzip压缩时候报错，不开启gzip使用注释部分则正常

关键代码片段：

const gzip = require('zlib').createGzip();

res.statusCode = 200;
res.setHeader('Content-Type', type);
res.setHeader('Content-Encoding', 'gzip');

// fs.readFile(pathname, (err, data) => {
//   res.end(data);
// })

fs.createReadStream(pathname).pipe(gzip).pipe(res); //关键语句

报错：

Error: write after end

较小的html文件能正确返回，比较大css和js却返回不了，请问下我这是哪里写错了或是少了什么吗？
