国庆来了，npm 的命令都不可以用：我新建了一个ionic的项目
ionic start ionc tabs
出现了这个报错：如下：
PS G:\lianxi\myionic02> ionic start myionic03 tabs
√ Creating directory .\myionic03 - done!
√ Downloading and extracting tabs starter - done!
? Would you like to integrate your new app with Cordova to target native iOS and Android? No
√ Personalizing ionic.config.json and package.json - done!
Installing dependencies may take several minutes.

图片看的应该更清晰一些：
百度，谷歌搜了很多，没有找到答案，我一直以为是node或者angular的问题，
后来某位大神给我说可能是ionic‘的问题，至此问题才得以解决：
在c盘找到了.npmrc这个文件
把第一行和第4行删除，
在此执行 ionic start ionc tabs
问题完美解决
