我在我的计算机上安装了Cordova和Ionic，之后通过输入ionic start demo blank创建了一个空白测试应用程序，但是我收到了错误并且无法处理它。
显示的结果如下：
ng directory .\demo - done!
ading and extracting blank starter - done!

我在此链接[ERROR] An error occurred while running npm install (exit code 1):上看到了同样的错误，但我不明白为什么我遇到此代理错误而且不知道如何解决它。
答案 0 :(得分：1)
我认为你在代理背后工作。这个或node-sass存储库不可用，因此您可以手动下载它：
npm install node-sass
如果你有一个错误，那么你肯定在代理＆amp;你应该根据你的操作系统进行配置。
修改
我只是运行命令＆amp;一切都好。该应用程序运行没有问题。我认为你有nodeJs或npm版本或离子CLI的问题。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
