一、下载Node.js

下载地址

二、配置环境变量

在CMD中运行node -v和npm -v这两条命令，如果都能输出版本号，说明nodejs安装成功。

三、配置NPM下载存放目录（文件不用事先创建）

npm config set prefix "D:\Software\node\node_global"

npm config set cache "D:\Software\node\node_cache"

四、NPM设置镜像仓库（淘宝镜像仓库）

npm config set registry https://registry.npm.taobao.org

在User文件夹下有一个.npmrc的文件，这里面就有刚刚为npm配置的信息。

五、vue-cli脚手架创建Vue3.0项目

1.安装最新班的vue-cli

npm install -g @vue/cli

or

yarn globaladd @vue/cli

安装成功后查看版本：vue -V(大写的V)

2.通过脚手架创建vue项目

vue create 项目名称

如果提示 ‘vue 不是内部命令’，此时需要对刚刚安装的vue-cli 3.0 设置环境变量添加到 path中。

此时再去创建vue项目即可（填写项目的基本配置信息）： vue create 项目名

下面是通过脚手架创建项目的过程：
