I can not move another path in Vue JS - vue.js

Im new to Vue JS and I'm making a simple page in Vue JS. Here are my codes:
main.js
import Vue from 'vue'
import App from './App.vue'
import PokeProfile from './components/PokeProfile.vue'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import VueRouter from 'vue-router';
Vue.use(VueRouter)
Vue.use(ElementUI)
const router = new VueRouter({
routes: [
{path: '/', component: App},
{path: '/pokemon/:id', component: PokeProfile},
],
mode: 'history'
})
//Vue.config.productionTip = false
new Vue({
el: '#app',
render: h => h(App),
router: router
})
App.js
<template>
<div id="app">
<div class="tag-group">
<el-tag
v-for="pokemon in pokemons"
:key="pokemon.national_id"
:type="pokemon.name"
effect="plain">
<poke-item :pokemon=pokemon></poke-item>
</el-tag>
</div>
</div>
</template>
<script>
import PokeItem from './components/PokeItem.vue'
import axios from 'axios'
export default {
name: 'app',
components: {
PokeItem
},
data() {
return {
pokemons: []
}
},
created() {
axios.get("http://localhost:3000")
.then(res => this.pokemons = res.data)
.catch(err => {console.log(err)})
}
}
</script>
<style>
div {
display: flex;
justify-content: center;
}
</style>
PokeItem.js
<template>
<div>
<router-link :to="pokemonLink">
{{pokemon.name}}
</router-link>
</div>
</template>
<script>
export default {
data() {
return {}
},
props: {
pokemon: {
type: Object,
required: true
}
},
computed: {
pokemonLink() {
return `/pokemon/${this.pokemon.national_id}`
}
}
}
</script>
PokeProfile.js
<template>
<h1>Hello Pokemon</h1>
</template>
<script>
export default {
}
</script>
The problem here is I can not move to PokeProfile.js when I click on an item in the PokeItem.js file. What could be the problem? I've checked the section of the code related to routing but I didn't see any problem.

Vue-Router uses a dynamic component (<router-view>) to render the components of your routes. Usually you will find this component in the template of your app.vue. Since you have no <router-view> component Vue-Router does not know where to render your route components.
Try this:
// main.js
import Home from './components/Home.vue'
const router = new VueRouter({
routes: [
{path: '/', component: Home},
{path: '/pokemon/:id', component: PokeProfile},
],
mode: 'history'
})
// components/Home.vue
// your old App.vue
// ./App.vue
<template>
<main>
<router-view></router-view>
</main>
</template>

new Vue({
router,
render: h => h(App)
}).$mount('#app')
Vue.use(router);
My router/index.js :
import Vue from 'vue'

import App from '../App.vue'
import Inscription from '../Inscription.vue'
Vue.use(Router)
const routes = [

For router to actually work you need a <router-view> component somewhere in your app. The best place is probably the App component. Check the docs
<router-view> works as a placeholder - router put there the component configured for a route when the route is active.
In that sense your / route should probably not use App component but something else - create another component for example Home which will be displayed on the root route (/)
const App = Vue.component('App', {
name: "App",
template: `
<div class="acceuil_main">
<div class="navbar_element">
<router-link :to="{name: 'Inscription'}">Inscription</router-link>
</div>
<router-view></router-view>
</div>
`
})
const Inscription = Vue.component('Inscription', {
template: `
<div>Inscription</div>`
})
const routes = [{
path: '/inscription',
name: 'Inscription',
component: Inscription
}]
const router = new VueRouter({
mode: 'history',
routes: routes
});
new Vue({
router,
render: h => h(App)
}).$mount('#app')
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app"></div>

vue router-view does not work if wrapped in a component

UPDATE:
It magically starts to work later on after I clear browser cache, I do not know what happened before.
I wonder how to include router-view in a component rather than directly use it?
For Example:
main.js
import Vue from 'vue'
import router from "./router"
import App from './App.vue'
new Vue({
el: '#app',
render: h => h(App),
router
})
App.vue
<template>
<div>
<page-content></page-content>
</div>
</template>
<script>
import pageContent from "./page-content.vue";
export default {
name: 'app',
data() { return {}; },
components: {
"page-content": pageContent
}
}
</script>
page-content.vue
<template>
<div class="page-content">
<router-view>
</router-view>
</div>
</template>
<script>
export default {
}
</script>
router.js
import Vue from "vue";
import VueRouter from "vue-router";
Vue.use(VueRouter);
const Foo = { template: '<div>foo</div>' }
const Bar = { template: '<div>bar</div>' }
const routes = [{ path: '/', component: Foo }]
export default new VueRouter({
routes
})
The problem is I can not see foo shown up on page

Vue.js : "$scrollTo" is not defined in inner template

When I am using another template (Header.vue) inside the main template Index.vue, it throws an error "$scrollTo" is not defined.
Note : $scrollTo is provided by the module "vue2-scrollspy" which I have installed.
However if I paste the entire code of Header.vue inside Index.vue it works fine.
Index.vue
<template>
<div class="scroll-div">
<mainheader></mainheader>
</div>
</template>
<script>
import mainheader from './Header.vue'
export default {
name: 'MyApplication',
components:{
mainheader
}
}
</script>
Header.vue
<template>
<div class="main-Header">
<b-navbar toggleable="md" type="dark" variant="dark" fixed="top">
<div class="container">
<b-navbar-brand #click="$scrollTo(0)"></b-navbar-brand>
</div>
</b-navbar>
</div>
</template>
<script>
export default {
name : 'mainheader',
data () {
return {
msg: 'Welcome to SportsBee',
scrollPos: 0
}
}
}
</script>
index.js
import Scrollspy from 'vue2-scrollspy';
Vue.use(Scrollspy);
Vue.use(VueAxios, axios);
Vue.use(VueRouter)
const router = new VueRouter({
routes: [
{
path: '/',
name: 'index',
component: index
}
], mode:"history"
})
export default router;
main.js
import Vue from 'vue'
import App from './App'
import router from './router'
new Vue({
el: '#app',
router,
template: '<App/>',
components: { App }
})

Can't use router-link inside Component

Ok so I started a basic VueJS with the VueCli.
This is my setup:
App.vue
<template>
<div id="app">
<router-link to="/home"><span>Home</span></router-link>
<router-view></router-view>
</div>
</template>
<script>
export default {
name: 'app'
}
</script>
Home.vue
<template>
<h1>{{ msg }}</h1>
</template>
<script>
export default {
name: 'home',
data () {
return {
msg: 'HomeView'
}
}
}
</script>
index.js from the router:
import Vue from 'vue'
import Router from 'vue-router'
import Home from '#/components/pages/Home'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/home',
name: 'Home',
component: Home
}
]
})
main.js:
import Vue from 'vue'
import App from './App'
import NavigationBar from './components/NavigationBar'
import router from './router'
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
template: '<App/>',
components: {App}
})
new Vue({
el: '#navigation-bar',
template: '<NavigationBar/>',
components: {NavigationBar}
})
This works perfectly fine. The routerlink works and display the Home.vue.
However I created a NavigationBar Component:
NavigationBar.vue
<template>
<div><span>Test</span>
<router-link to="/home"><span>Home</span></router-link></div>
</template>
<script>
export default {
name: 'navigationBar',
data () {
return {
}
}
}
</script>
When I now delete the router-link in the App.vue and add the navigation-bar ID I cant see the router-link. But the NavigationBar gets loaded, because I see the Test Span:
App.vue
<template>
<div id="app">
<div id="navigation-bar"></div>
<router-view></router-view>
</div>
</template>
Why doesnt it work? The router-link is just inside a template and I get no error message.

Vue-router can't render component correctly with Element-UI

I am trying to use Vue-router with Element-UI( http://element.eleme.io/#/en-US/component/quickstart ). But I face some weird condition. Following is my app.js, where I create my vue-router instance.
import Vue from 'vue'
import VueRouter from 'vue-router'
import Vuex from 'vuex'
import ElementUI from 'element-ui'
import locale from 'element-ui/lib/locale/lang/zh-TW'
import 'element-ui/lib/theme-default/index.css'
import myComponent from './vue/page/mycomponent.vue'
import App from './vue/app.vue'
Vue.use(VueRouter)
Vue.use(Vuex)
Vue.use(ElementUI, {locale})
const router = new VueRouter({
routes: [
{path: '/mypage', component: myComponent}
],
})
const app = new Vue({
router: router,
store: store,
el: '#v-app',
render: h => h(App),
})
And I put my router-view tag in app.vue .
<template lang="pug">
#v-app
v-sidebar(:pages="pages")
router-view
</template>
<script>
import Sidebar from './sidebar.vue'
export default {
name: 'App',
data() {
return {
pages: [],
}
},
components: {
'v-sidebar': Sidebar,
},
}
</script>
<style lang="sass" scoped>
</style>
Here is my router-link in sidebar.vue.
<template lang="pug">
#sidebar
template(v-for="page in pages")
router-link(:to="{path: page.prop}")
i(class="chevron right icon")
span {{page.label}}
</template>
<script>
export default {
name: 'Sidebar',
data() {
return {
defaultProps: {
label: 'label',
children: 'children',
},
pages:[{label: 'link-1', prop: 'mypage'}]
}
},
}
</script>
If I strictly go to "/mypage" then it will render correctly. But if I click the link in my sidebar component, the page component won't render completely. I am wonder if there is somewhere I missed or what should I do to fix this kind of situation.
