小编Din*_*hah的帖子

我试图使用模式验证输入类型="文本",我只想要文本.

零件 :

 this.from = this.fb.group({
  name: ['',[Validators.required,Validators.pattern('/^[a-zA-Z]+$/')]],

});

Html:

<input type="text" formControlName="name"/> // omitting other html template like from tag.

以上模式验证对我不起作用,它将始终返回无效状态.

我试图用aot编译我的项目,但是当我尝试命令时

ngc -p tsconfig-aot.json

它在第一次使用ngFactroy生成aot文件夹,但是当我更改主要ts(如角度文档中提到的)为bootstrap新生成的ngmodulefactory并使用相同的命令重新编译项目时,我得到以下错误

难道我做错了什么 ？
