全局安装webpack npm i -g webpack --registry=https://registry.npm.taobao.org
配置环境变量
假如webpack.cmd路径是C:\Users\xiaopeng\AppData\Roaming\npm\webpack.cmd
需要把C:\Users\xiaopeng\AppData\Roaming\npm配置在window环境变量里
C:\Users\xiaopeng>npm i -g webpack --registry=https://registry.npm.taobao.org
C:\Users\xiaopeng\AppData\Roaming\npm\webpack -> C:\Users\xiaopeng\AppData\Roaming\npm\node_modules\webpack\bin\webpack.js
