我在我的计算机上安装了Cordova和Ionic，然后通过键入ionic start demo blank创建了一个空白的测试应用程序，但是我有错误并且无法处理。
所示的结果就是这样：
ng directory .demo - done!
ading and extracting blank starter - done!

我在此链接上看到了大约相同的错误[错误]运行NPM安装时发生错误。
我认为您在代理后面工作。那或node-sass存储库都不可用，因此您可以手动下载它：
npm install node-sass
如果您陷入错误，那么您肯定会在代理＆amp;您应该根据您的操作系统进行配置。
编辑：
我刚刚运行命令＆amp;一切安好。该应用程序运行没有问题。我认为您对nodeJs或NPM版本或离子CLI有问题。尝试下载最新的nodeJs＆amp;尝试使用以下命令更新npm：
npm install npm@latest
我的配置是：
CLI软件包：
@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
