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。
npm config set prefix "D:\Software\node\node_global"
npm config set cache "D:\Software\node\node_cache"
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。
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
