[windows] install cross-env with cnpm instead of yarn or npm

环境是 windows下通过vagrant运行虚拟机（ubuntu）

Host：windows 10

Guest： ubuntu（vagrant）

根据之前的经验，不要在 Guest环境中执行npm install操作

大坑：虚拟机共享目录中不要进行任何的开发工作

所以在 Host环境中安装

 ganik@ddhc MINGW64 /d/Code/go-laravel/weibo (filling-layout-style)
 $ yarn add cross-env --no-bin-links
 yarn add v1.16.0

看似安装好了，其实上面是有警告的，cross-env也并没有成功安装

 ganik@ddhc MINGW64 /d/Code/go-laravel/weibo (filling-layout-style)
 $ npm run dev

 > @ dev D:\Code\go-laravel\weibo
 > npm run development

 > @ development D:\Code\go-laravel\weibo
 > cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

安装 cnpm

 ganik@ddhc MINGW64 /d/Code/go-laravel/weibo (filling-layout-style)
 $ npm install -g cnpm --registry=https://registry.npm.taobao.org

 C:\Users\ganik\AppData\Roaming\npm\cnpm -> C:\Users\ganik\AppData\Roaming\npm\node_modules\cnpm\bin\cnpm
 + cnpm@6.1.
 added  packages from  contributors in .846s

用 cnpm 安装 cross-env

 ganik@ddhc MINGW64 /d/Code/go-laravel/weibo (filling-layout-style)
 $ cnpm install cross-env --no-bin-links
 √ Installed  packages
 √ Linked  latest versions
 √ Run  scripts
 √ All packages installed ( packages installed from npm registry, used 1s(network 1s), speed .17kB/s, json (.42kB), tarball .32kB)

cross-env 正常运行了

 ganik@ddhc MINGW64 /d/Code/go-laravel/weibo (filling-layout-style)
 $ npm run dev

 > @ dev D:\Code\go-laravel\weibo
 > npm run development

 > @ development D:\Code\go-laravel\weibo
 > cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js
