在Visual Studio 2017 Angular 7项目中，我正在使用PrimeNG版本6.1.7。我有一个包含多个子组件的组件，其中一些子组件使用PrimeNG日历。到2019年3月6日，这一切都没有问题，当时我向客户交付了工作代码。
但是，如果我从代码存储库中提取相同的代码并立即运行应用程序，则单击input元素只会显示该元素呈现的灰色叠加层：
<div class="ui-widget-overlay ui-datepicker-mask ui-datepicker-mask-scrollblocker" style="z-index: 1002;"></div>
在chrome中进行调试时，如果我单击其他应用程序（即使是Chrome的DevTools窗口，也未从主窗口中停靠），然后再点击叠加层，就会突然显示日期选择器，并且同时我在DevTools的Elements标签中看到以下html，位于上面引用的div的正下方：
<div class="ng-trigger ng-trigger-overlayAnimation ng-tns-c23-2 ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-shadow ui-datepicker-touch-ui ng-star-inserted" ng-reflect-ng-class="[object Object]" style="z-index: 1004; transform: translate(-50%, -50%); opacity: 1;">
!-- TONS OF HTML FOR THE DATEPICKER -->
</div>
如前所述，我没有做任何更改，所以我猜测这是由于package.json文件中每个设置的更新引起的。
我无法为自己的生活弄清楚发生了什么事。如果我删除“ touchUI = true”属性，则日历会出现，但不会在屏幕上正确居中（这是移动友好型应用程序）。任何帮助将不胜感激。
示例日期控件（应用程序中的所有控件都有相同的问题）：
<p-calendar [(ngModel)]="labor.laborServiceDate" [touchUI]="true"></p-calendar>
