如何渲染 primevue 按钮？

Question

main.js

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

import PrimeVue from "primevue/config";
import Button from 'primevue/button'

import 'primevue/resources/themes/saga-blue/theme.css'
import 'primevue/resources/primevue.min.css'                 // core css
import 'primeicons/primeicons.css'


const app = new Vue({
  render: h => h(App),
})
app.$mount('#app')
app.use(PrimeVue)
app.component('Button', Button)

App.vue

<template>
  <div id="app">
    <NewCompany/>
  </div>
</template>

<script>
import NewCompany from './components/NewCompany'

export default {
  name: 'App',
  components: {
    NewCompany
  }
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

components/NewCompany.vue

<template>
  <div>
      <Button label="New">Tes</Button>
      test
  </div>
</template>

<script>

import Button from 'primevue/button';


export default {
    name: 'NewCompany',
    components: {
        Button
    },
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

div {
    border: 1px solid;
}
</style>

index.html

<!DOCTYPE html>
<html lang="">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">

  </head>
  <body>
    <noscript>
      <strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
    </noscript>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

我正在尝试根据 primevue 文档中的视频渲染按钮：https://www.youtube.com/watch?v=cGTXuyqIwMA&t=623s&ab_channel=CagatayCivici

它没有显示任何按钮：

并且在检查 html 时，有这个：

<div id="app"><div data-v-964ceb26=""><!----> test </div></div>

控制台错误：

为什么它告诉对象不是函数？它在谈论哪个对象？

Answer 1

首先-安装的版本是2，需要重新安装到版本3。使用vue cli安装时，它会提供一个选择版本的菜单。

components/NewCompany.vue

<template>
  <div>
      <Button label="New"></Button>
  </div>
</template>

<script>

import Button from "primevue/button";

export default {
  name: 'NewCompany',
  components: {
      Button
  },
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
/* todo use bootstrap */
    div {
        border: 1px solid;
        text-align: left;
    }
</style>

App.vue

<template>
  <NewCompany/>
</template>

<script>
import NewCompany from './components/NewCompany.vue'

export default {
  name: 'App',
  components: {
    NewCompany
  }
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

main.js

import { createApp } from 'vue'
import App from './App.vue'

import 'primevue/resources/themes/saga-blue/theme.css'
import 'primevue/resources/primevue.min.css'                 // core css
import 'primeicons/primeicons.css'

createApp(App).mount('#app')
