前情提要:

多看一眼

1.涉及有关的组件安装为了防止运行出错可以使用我@的版本
2.记得要安装了淘宝的镜像加速器(cnpm)组件才可以使用cnpm指令※※※※※※※※※※

留心版本,我试过都用最新版,发现出现了一堆版本兼容问题.用我推荐的版本可以完美运行出来狂老师的vue工程小demo

1.Node.js@v12.13.0版本 下载地址:node.js官网
2.安装node.js淘宝镜像加速器(cnpm) npm install cnpm -g
3.vue-cli cnpm instal1 vue-cli-g
4.webpack@4.41.2版本cnpm install webpack@4.41.2 -g
5.webpack-cli@3.3.9版本cnpm install webpack-cli@3.3.9 -g
6.vue@2.96版本
7.vue-router@3.1.3版本cnpm install vue-router@3.1.3 --save-dev
8.node-sass: @4.5.3版本cnpm install node-sass@4.5.3
9. sass-loader@7.3.1版本cnpm install sass-loader@7.3.1

Help:

一定一定一定要统一版本不然到时很多莫名其妙的err.和一堆要几个小时查资料解决的版本不兼容问题

其实说白了:说有用cnpn 指令进行安装的组件版本都可以在package.json中修改然后使用cnpm install进行安装.付上我的package.json

正式开始

步骤

1.使用终端(cmd)到一个空的文件夹 //cd 指令
2.终端输入vue init webpack hello-vue //创建一个名为hello-vue的工程
3.终端进入hello-vue文件夹 //cd指令
4.安装依赖
①路由: cnpm install vue-router@3.1.3 --save-dev
②ElementUI(饿了么UI):npm i element-ui -S
③package.json内容的安装:cnpm install
④sass加载器:cnpm install sass-loader@7.3.1 node-sass@4.5.3 --save-dev
5.启动测试在hello-vue文件夹下的终端(cmd)输入命令:npm run dev

出现这个就成功了,只需要打开浏览器,在网址输入该地址:http://localhost:8080
即可进入项目页面
6.结束,关于安装的这些路由,sass加载器,ElementUI组件的其他使用在这里就不一一讲了.大家可以到B站看视频,我的能力怕讲了误导了大家
