Node.js

Easiest solution would be to try the following to cleanup your node issues and reinstall a clean version.

First remove everything related to node

sudo apt-get purge --auto-remove nodejs npm

UPDATE For yum:

yum clean all
yum -y remove nodejs

Remove these leftover files and folders as well

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp /opt/local/bin/node opt/local/include/node /opt/local/lib/node_modules 

Then install node back with nvm,

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash

//To uninstall a node version 
//nvm uninstall <current version>

nvm install 8.8.1

nvm use 8.8.1

//check with 
node -v
npm -v


//**UPDATE**: Install your package
npm install -g n

And all should work.

UPDATE : Install Without NVM

yum install -y gcc-c++ make
curl -sL https://rpm.nodesource.com/setup_8.x | sudo -E bash -

yum install nodejs
node -v

//Install your package
npm install -g n

nvm list

This command worked fine for me. It will list all the installed versions of node under nvm
