var MyClassStub = sinon.createStubInstance(MyClass);

MyClassStub不包含静态方法.如何解决？

我正在尝试将一个对象写入流：

const fs = require('fs');

const stream = fs.createWriteStream('index.json', {objectMode: true});
stream.write({"a":1});

stream.end();

根据文档，我可以通过传递选项来做到这一点{objectMode: true}，但我收到错误：

events.js:182
      throw er; // Unhandled 'error' event
      ^

Error: Invalid data
