要使用Vue.js和Vite构建impart-lab-portal的门户网站，你需要按照以下步骤操作：

1. 安装Node.js和npm（Node包管理器），以便在计算机上安装所需的依赖项。

2. 克隆impart-lab-portal的源代码仓库到本地计算机。

3. 进入源代码目录并运行以下命令以安装依赖项：

npm install -g create-vite

4. 创建一个新的Vue项目，使用以下命令：

create-vite my-vue-project

5. 进入新创建的Vue项目目录并运行以下命令以安装Vite插件：

cd my-vue-project

npm install vite@next --save-dev

6. 在`package.json`文件中添加以下内容：

{

  "scripts": {

    "serve": "vite",

    "build": "vite build"

  },

  "extends": "plugin:@/vite/config/base"

}

7. 在`src`目录下创建一个名为`main.js`的文件，并在其中添加以下代码：

import { createApp } from 'vue'

import App from './App.vue'

import router from './router'

import store from './store'



const app = createApp(App)

app.use(router)

app.use(store)

app.mount('#app')

8. 在`src`目录下创建一个名为`router`的文件，并在其中添加以下代码：

import { createRouter, createWebHistory } from 'vue-router'

import Home from '../views/Home.vue'

import About from '../views/About.vue'



const routes = [

  { path: '/', component: Home },

  { path: '/about', component: About }

]



const router = createRouter({ history: createWebHistory(), routes })

export default router

9. 在`src`目录下创建一个名为`store`的文件，并在其中添加以下代码：

import { createStore } from 'vuex'

import axios from 'axios'



export const state = () => ({

  user: null

})



export const mutations = {

  setUser(state, user) {

    state.user = user

  }

}



export const actions = {

  async getUser({ commit }) {

    const response = await axios.get('/api/user')

    commit('setUser', response.data)

  }

}



export const getters = {

  user: state => state.user

}



const store = createStore(state, mutations, actions)

export default store

10. 在`src`目录下创建一个名为`views`的文件，并在其中添加以下代码：

  

    {{ $t("home.title") }}

    

    

  







import { defineComponent } from 'vue'

import { useRoute, useRouteMatch } from 'vue-router'

import { useStore } from 'vuex'

import { mapState, mapMutations } from 'vuex'

import Home from '../views/Home.vue'

import About from '../views/About.vue'

import { getUser } from '../store'



export default defineComponent({

  setup() {

    const match = useRouteMatch('/')

    const route = useRoute(match)

    const store = useStore()

    const user = useStore(mapState(['user']))

    const { mutate } = store



    return () => {

      return (

        

          {route.meta.title}

          

          

        

      )

    }

  },

  computed: {

    $t: (key) => key.replace('$', '_') + '.' + key.split('_').pop()

  }

})

11. 在`src`目录下创建一个名为`views`的文件，并在其中添加以下代码：

  

    {{ $t("home.title") }}

    

    

  







import { defineComponent } from 'vue'

import { useRoute, useRouteMatch } from 'vue-router'

import { useStore } from 'vuex'

import { mapState, mapMutations } from 'vuex'

import Home from '../views/Home.vue'

import About from '../views/About.vue'

import { getUser } from '../store'



export default defineComponent({

  setup() {

    const match = useRouteMatch('/')

    const route = useRoute(match)

    const store = useStore(mapState(['user']))

    const { mutate } = store



    return () => {

      return (

        

          {route.meta.title}

          

          

        

      )

    }

  },

  computed: {

    $t: (key) => key.replace('$', '_') + '.' + key.split('_').pop()

  }

})

12. 在`src`目录下创建一个名为`views`的文件，并在其中添加以下代码：

  

    {{ $t("about.title") }}

    

  







import { defineComponent } from 'vue'

import { useRoute, useRouteMatch } from 'vue-router'

import { useStore } from 'vuex'

import { mapState, mapMutations } from 'vuex'

import Home from '../views/Home.vue'

import About from '../views/About.vue'

import { getUser } from '../store'



export default defineComponent({

  setup() {

    const match = useRouteMatch('/')

    const route = useRoute(match)

    const store = useStore(mapState(['user']))

    const { mutate } = store



    return () => {

      return (

        

          {route.meta.title}

          

          

        

      )

    }

  },

  computed: {

    $t: (key) => key.replace('$', '_') + '.' + key.split('_').pop()

  }

})
