我正在尝试使以下代码起作用：

var stream = require('stream');

class MyReadable extends stream.Readable {
  constructor(options) {
    super(options);
  }
  _read(size) {
    this.push({a: 1});
  }
}

var x = new MyReadable({objectMode: true});
x.pipe(process.stdout);

根据node.js的Streams文档，由于objectMode选项设置为true，因此从此类流中读取非字符串/非Buffer对象应该没有问题。但是我最终遇到了以下错误：
