Vue技术点整理-Vue CLI安装详解

 一，脚手架安装

Node 版本要求

Vue CLI 需要 Node.js 8.9 或更高版本 (推荐 8.11.0+)。你可以使用 nvm 或 nvm-windows 在同一台电脑中管理多个 Node 版本。

1，全局安装Vue CLI

npm install -g @vue/cli
# OR
yarn global add @vue/cli

安装之后，使用以下命令查看安装是否正确

vue --version

2，快速创建一个CLI项目

vue create cli_test

此时会出现以下安装选项：

• 选择安装选项

PS E:workspacedemo> vue create cli_test

• 安装完成后的目录结构如下：

• 启动项目

cd cli_test

npm run serve

浏览器输入http://localhost:8080

• 部署打包项目

npm run build

执行后，会多一个dist的目录，直接把这个目录放到服务器Nginx下就可以访问了

CLI默认配置只是简单的项目框架，更多配置、组件封装请参考我其它的文章！
