我已经看到了关于这个链接[ERROR] An error occurred while running npm install (exit code 1):同样的错误，但我不明白为什么我得到这个代理的错误，不知道如何解决它。
我认为你是在一个代理工作。或许到那时节点萨斯库不可用，所以你手动下载：
npm install node-sass
如果窗台有一个错误，那么你肯定是在代理工作，与你应该配置它根据您的操作系统。
编辑：
我只是执行命令和一切都很好。该应用程序运行没有问题。我觉得你有nodeJs或NPM版本或离子CLI的问题。尝试下载最新nodeJs和尝试更新npm用下面的命令：
npm install npm@latest
我的配置是：
CLI包：
@ionic/cli-plugin-proxy : 1.5.6
@ionic/cli-utils : 1.19.0
ionic (Ionic CLI) : 3.19.0
System:
Node : v6.11.5
npm : 3.10.10
OS : Linux 4.4
