Vue.js 更新到Vue 2.6和PrimeVue 2.4-无法读取属性'；ripple'；未定义的

在使用Serenity模板将primevue更新到2.4.x之后，我在仪表板上发现了大约200多个控制台错误：

[Vue warn]: Error in directive ripple inserted hook: "TypeError: Cannot read property 'ripple' of undefined"    
found in    
---> <AppSubmenu> at src/AppSubmenu.vue
       <AppMenu> at src/AppMenu.vue
         <App> at src/App.vue
           <AppContainer> at src/AppContainer.vue
             <Root>

我怎样才能摆脱它

非常感谢
