1.使用命令行创建一个hello-vue的一个项目

vue init webpack hello-vue

2.然后我们需要安装依赖，依次安装你所需要的依赖，这里我们需要下载的有vue-router,element-ui,sass-loader和node-sass四个插件

cd hello-vue    #进入项目文件夹
npm install vue-router --save-dev #安装vue-router
npm i element-ui -S #安装element-ui
npm install #安装依赖
cnpm install sass-loader node-sass --save-dev #安装sass加载器
npm run dev #启动测试

3.前面两步的效果如下：

C:\Users\黄帅\Desktop>vue init webpack hello-vue

? Project name hello-vue
? Project description A Vue.js project
? Author huangshuai12311 <2548262291@qq.com>
? Vue build standalone
? Install vue-router? No
? Use ESLint to lint your code? No
? Set up unit tests No
? Setup e2e tests with Nightwatch? No
? Should we run `npm install` for you after the project has been created? (recommended) no

   vue-cli · Generated "hello-vue".

# Project initialization finished!
# ========================

To get started:

  cd hello-vue
  npm install (or if using yarn: yarn)

 I  Your application is running here: http://localhost:8080

4.访问http://localhost:8080我们即可以看到一个vue项目被我们搭建完成

image-20210202214736716.png

5.下面我们用idea打开我们创建的项目，然后可以进行一些操作了
6.此刻需要编写一个登陆界面，在src的下新建一个view的目录，然后新建一个view/login.vue

<template>
  <div class="login-container">
    <el-form :model="ruleForm2" :rules="rules2"
             status-icon
             ref="ruleForm2"
             label-position="left"
             label-width="0px"
             class="demo-ruleForm login-page">
      <h3 class="title">系统登录</h3>
      <el-form-item prop="username">
        <el-input type="text"
                  v-model="ruleForm2.username"
                  auto-complete="off"
                  placeholder="用户名"
        ></el-input>
      </el-form-item>
      <el-form-item prop="password">
        <el-input type="password"
                  v-model="ruleForm2.password"
                  auto-complete="off"
                  placeholder="密码"
        ></el-input>
      </el-form-item>
      <el-checkbox
        v-model="checked"
        class="rememberme"
      >记住密码</el-checkbox>
      <el-form-item style="width:100%;">
        <el-button type="primary" style="width:100%;" @click="handleSubmit" :loading="logining">登录</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>

<script>
    export default {
        data(){
            return {
                logining: false,
                ruleForm2: {
                    username: 'huangshuai',
                    password: '123456',
                },
                rules2: {
                    username: [{required: true, message: 'please enter your account', trigger: 'blur'}],
                    password: [{required: true, message: 'enter your password', trigger: 'blur'}]
                },
                checked: false
            }
        },
        methods: {
            handleSubmit(event){
                this.$refs.ruleForm2.validate((valid) => {
                    if(valid){
                        this.logining = true;
                        if(this.ruleForm2.username === 'admin' &&
                            this.ruleForm2.password === '123456'){
                            this.logining = false;
                            sessionStorage.setItem('user', this.ruleForm2.username);
                            this.$router.push({path: '/'});
                        }else{
                            this.logining = false;
                            this.$alert('username or password wrong!', 'info', {
                                confirmButtonText: 'ok'
                            })
                        }
                    }else{
                        console.log('error submit!');
                        return false;
                    }
                })
            }
        }
    };
</script>

<style scoped>
  .login-container {
    width: 100%;
    height: 100%;
  }
  .login-page {
    -webkit-border-radius: 5px;
    border-radius: 5px;
    margin: 180px auto;
    width: 350px;
    padding: 35px 35px 15px;
    background: #fff;
    border: 1px solid #eaeaea;
    box-shadow: 0 0 25px #cac6c6;
  }
  label.el-checkbox.rememberme {
    margin: 0px 0px 15px;
    text-align: left;
  }
</style>

7.然后我们编写一个路由，用来访问login的时候跳转成功，在src目录下新建一个router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/views/TheLogin'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    },
  ]
})

8.然后我们需要在app.vue中修改代码如下

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

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

9.然后我们在idea的命令行中启动项目 npm run dev

10.以上就是vue项目的基本环境的搭建！
