对于仍然遇到此问题的任何人，请尝试以下操作:

For anyone still running into this issue, try this:

Angular2+:IE 11 无法获取未定义或空引用的属性调用"

如果您遇到的错误发生在如下所示的一大段代码上:

If the error you're getting occurs on a hunk of code that looks like this:

window.setTimeout(() => {
    window.removeEventListener('click', suppressClick, true);
}, 0);

...然后请告诉我该解决方案是否有效.我会更新这个答案，并可能将此问题标记为重复.

...then please let me know if the solution worked or not. I will update this answer, and possibly mark this question as duplicate.

我不认为这些是同一个问题，因为错误发生在 bundle.js 中的不同代码上.有人对这个答案投了反对票，但没有给出任何关于这些问题是否有相同解决方案的反馈.

I DO NOT BELIEVE THESE TO BE THE SAME ISSUE AT THIS TIME, AS THE ERRORS OCCURRED ON DIFFERENT CODE IN bundle.js. Someone voted this answer down, without giving any feedback on whether or not these questions have the same solution.

我目前没有办法对此进行测试，但想将人们引向可能的解决方案.

I do not have a way to test this currently, but wanted to direct folks to a possible solution.
