2、新建shop-vue项目

使用 webpack 初始化项目：

$ vue init webpack shop-vue? Project name shop-vue
? Project description A Vue.js project
? Author zsx242030 <15110820283@163.com>
? Vue build standalone
? Install vue-router? Yes
? 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) novue-cli · Generated "shop-vue".# Project initialization finished!
# ========================To get started:cd shop-vuenpm install (or if using yarn: yarn)npm run devDocumentation can be found at https://vuejs-templates.github.io/webpack

生成的项目结构如下：

然后执行 npm install 和 npm audit fix 安装一些相关的依赖，会生成 node_modules 目录：

build：项目构建(webpack)相关代码

config：配置目录，包括端口号等

node_modules ：npm加载的项目依赖块

src：这里是我们要开发的目录，基本上要做的事情都在这个目录里。里面包含了几个目录及文件：

assets: 放置一些图片，如logo等

components：该目录里存放的我们的开发文件组件，主要的开发文件都存放在这里了

App.vue：项目入口文件

main.js：项目的核心文件

router：路由配置目录

static：放置一些静态资源文件

.babelrc：用来设置转码的规则和插件的

.editorconfig：用于定义编码样式的文件格式和一组文本编辑器插件组成

.gitignore：这些是一些配置文件，包括语法配置，git配置等

.postcssrc.js：为了进行移动端适配，PostCss 是一个处理 CSS 的处理工具

index.html：首页入口文件

package.json：项目配置文件

README.md：项目的说明文档，markdown 格式

使用 npm run dev 启动项目，访问 http://localhost:8080：

接下来使用开发工具打开项目：

对代码进行修改：

App.vue 修改为：

<template><div id="app"><router-view/></div>
</template><script>
export default {name: 'App'
}
</script><style>
</style>

main.js 修改为：

import Vue from 'vue'
import App from './App'
import router from './router'Vue.config.productionTip = falsenew Vue({el: '#app',router,components: { App },template: '<App/>'
})

将 HelloWorld.vue 删除，并且在src下新建 views 文件夹， 在该文件夹下新建 Index.vue，其内容改为:

<template><div class="index"><h1>首页</h1></div>
</template><script>
export default {name: 'Index',data () {return {}}
}
</script><style scoped>
</style>

修改 src/router/index.js 为：

import Vue from 'vue'
import Router from 'vue-router'
import Index from '../views/Index'Vue.use(Router)export default new Router({routes: [{path: '/',name: 'Index',component: Index}]
})

重新访问项目：

至此，前端项目的框架搭建完毕，接下来编写具体的页面。

3、相关依赖

# 使用element-ui,安装element-ui
npm i element-ui -S# 前后端交互axios
npm install axios# 数据存储vuex
npm install vuex --save# 安装字体
npm install font-awesome# 安装comment
npm install commentnpm install vue-router --save-dev
npm install sass-loader node-sass --save-dev

4、npm依赖下载失败解决

# npm清空下载的包
npm cache clean --force 或者
npm cache clear --force && npm install --no-shrinkwrap --update-binary

5、错误

【npm错误】- npm ERR code ERESOLVE 和 npm ERR ERESOLVE could not resolve 问题

# 解决
npm i --legacy-peer-deps
