npm is broken, need to reinstall node

just encountered this problem. If you use n packages to manage node versions, be sure to add sudo, that is, sudo n when switching, otherwise, although node-v displays normally, the install command will not be used

sudo chmod -R 777 /var/root

npm install koa  -g --unsafe-perm
