安装VUE
1.下载并安装Nodejs ,从官网下载LTS版(https://nodejs.org/en/)
检查是否安装完成,安装Nodejs同时会安装npm
node -v
npm -v
2.以npm方式全局安装Vue-cli(npm install --global vue-cli)
npm WARN deprecated vue-cli@2.9.6: This package has been deprecated in favour of @vue/cli npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142 npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has moved to "coffeescript" (no hyphen) npm WARN deprecated mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

3.vue项目初始化命令如下,若没有安装webpack,则先安装webpack
npm install -g webpack
vue init webpack myVue
注:安装过程 中有个选项(Use ESLint to line your code ?选择 No )
坑:如果你想安装3.X,则应如下操作
卸载2.X:
npm uninstall -g vue-cli 或 yarn global remove vue-cli
安装3.X:
npm install -g @vue/cli 或 yarn global add @vue/cli
4、进入到myVue目录下,使用npm install 安装package.json包中的依赖
命令如下:
cd myVue
npm install
5、运行项目:
npm run dev
在浏览器上输入:localhost:8080,将会出现下面的vue初始页面:
6、Ctrl+C,Y退出
注:
由于安装了vue cli 3.x版本无法使用init指令,可使用安装init指令模块:
npm install -g @vue/cli-init
