You are calling init twice. Go through your code and remove one instance.
您正在调用 init 两次。检查您的代码并删除一个实例。

I received this error with FF that does support this method but I forgot to change windowto my frame window object!
我收到了支持此方法的 FF 的此错误，但我忘记更改window为我的框架窗口对象！
console.log(getComputedStyle(window.document.querySelector('.tip > .tip.top'), ':after').getPropertyValue('left'));

Note that the above error pops up even if your windowobject is ok but the querySelectorreturns nothing! (I suspect it's your case).
请注意，即使您的window对象querySelector没问题，也会弹出上述错误，但没有返回任何内容！（我怀疑这是你的情况）。
