不知道我错过了什么。当我使用 ng build 和 ng serve 在本地运行它时，这可以正常工作

但是当我转向生产时，它开始表现得像这样。然后我尝试在我的本地使用ng build --prod和复制ng serve --prod。现在我也可以在本地重现该问题。

我想要什么：日期选择器弹出窗口应该以正确的样式出现，并且应该能够选择日期

现在正在做什么：在本地它正在使用 ng build 和 ng serve

问题是什么：在 prod （或使用ng build --prodand ng serve --prod）中，弹出窗口显示为空。请看下图

我尝试过的：经过研究，我发现了一些可以尝试的建议，ng serve --prod --build-optimizer=false也可以通过制作"buildOptimizer": false来尝试angular.json

错误：当我点击日期选择器图标时，我会出现以下错误

TypeError: Cannot read property 'getElementsByClassName' of

请让我知道调试此问题需要更多信息。我正在考虑创建一个 stackblitz，但它似乎在 stackblitz 中工作。

似乎是材料日期选择器的缺陷。不是解决方案，而是对我有用的解决方法。您可以尝试在您的angular.json

"optimization": false
"aot": false
"buildOptimizer": false
