npm ERR！更新角4

Question

我试图用这个COMAND更新Angular2到角4：

npm install @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] [email protected] --save 

，并显示此错误：

npm ERR! code ECONNRESET 
npm ERR! errno ECONNRESET 
npm ERR! syscall read 
npm ERR! network read ECONNRESET 
npm ERR! network This is most likely not a problem with npm itself 
npm ERR! network and is related to network connectivity.

任何人可以帮助我吗？

你是否设置了你的npm代理？
