Question

我制造了Ionic 4并准备投入生产。离子性饮料投放时没有错误或警告，但是当我运行Ionic build --prod时。这些错误：

ERROR in src/app/baby/baby.page.html(6,9): : Property 'buttonIcon' does not exist on type 'BabyPage'.
src/app/baby/baby.page.html(5,9): : Property 'Back' does not exist on type 'BabyPage'.

src/app/register/register.page.html(10,13): : Property 'Back' does not exist on type 'RegisterPage'.

That's some of the relavant code:
<ion-toolbar>
  <ion-buttons slot="start">
    <ion-back-button
        defaultHref="home"
        [text]="Back"
        [icon]="buttonIcon">
    </ion-back-button>
  </ion-buttons>
  <ion-buttons slot="secondary">

解决了该问题。原来， [text] =“返回” [icon] =“ buttonIcon” 后退按钮不需要工作。由于某种原因，即使没有或不需要这样的属性，它也是官方ionic 4文档中代码片段的一部分。刚删除它们，它就起作用了。

Ionic 4-构建为PWA，应用程序运行且无错误，但构建失败
