Vue 在本地开发的时候正常，在布到服务器的时候，运行 npm run build 提示如下错误

[root@VM_0_15_centos starve]# npm run build

> vue-test@1.0.0 build /var/www/html/starve
> cross-env NODE_ENV=production webpack --progress --hide-modules

sh: cross-env: command not found

npm ERR! There is likely additional logging output above.

解决办法： 安装的时候用 npm install -D 安装开发环境
而不是 npm install

然后就可以了

[root@VM_0_15_centos starve]# npm run build 

> vue-test@1.0.0 build /var/www/html/starve
> cross-env NODE_ENV=production webpack --progress --hide-modules
