npm install报错！

出现场景：当我下拉一个新的项目的时候，执行install报下边的错：

npm ERR! code EPERM
npm ERR! syscall unlink
npm ERR! path F:\yyzsofwer\xxxx.js
npm ERR! errno -4048
npm ERR! Error: EPERM: operation not permitted, unlink 'F:\yyzsofwer\invtSVN\IPQS\IPQS\node_modules\.xxxx.js'

原因：我的原因是因为后端tomcat把8080给占用了，所以install会报错

解决办法：将后端tomcat给停了，然后install就解决了
