NPM doesn't work after doing node update

[captaineramirez]

Hello,

I've got npm errors after doing node update (old node version v4.3.2 and new node version v9.8.0)...

I did :

sudo npm cache clean -f
Result : npm WARN using --force I sure hope you know what you are doing.

sudo npm install -g n
Results : /usr/local/bin/n -> /usr/local/lib/node_modules/n/bin/n
n@2.1.8 /usr/local/lib/node_modules/n

sudo n latest
Result : noting

sudo npm install -g npm
Results :
npm ERR! code MODULE_NOT_FOUND
npm ERR! Cannot find module 'internal/util/types'

npm ERR! A complete log of this run can be found in:
npm ERR! /root/.npm/_logs/2018-03-11T16_20_31_472Z-debug.log
