步进器 - 角度材料 - 无法读取未定义的属性'markForCheck'

提问于

无法获得角材料步进精细 . 询问的步进器显示和单击 Headers 时的步进显示正在移动，但是出现错误并说：

无法读取未定义的属性markForCheck

另外，当我想使用按钮指令抛出一个错误，如，

无法读取undefined之前的属性

也许有些帮助

代码：我只是复制粘贴角度材质页面中的默认代码：

https://material.angular.io/components/stepper/overview

我从我的主要加载儿童模块中的角度材料 .

也许延迟加载导致这个问题？

    将我的打字稿转换为es6时，我遇到了同样的问题 . Chrome似乎没有识别es6模块，因此没有为材料的步进器加载必要的导入 .

    检查你的tsconfig.json（不是tsconfig.app.json）你是否将你的打字稿转换为es6？如果是这样，你可以改为es5，它现在适合我

    tsconfig.json 
{
  ...
  "compilerOptions": {
    ...
    "target": "es5",
    ...
  }
}
