• How did you install nvm? (e.g. install script in readme, Homebrew): install script

• What steps did you perform?
  sudo apt-get install nodejs
  sudo apt-get install npm
  sudo apt-get install nodejs-legacy

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

nvm install 8.11.1
nvm alias default 8.11.1
nvm use default

• What happened?
  node -v
  v8.11.1

nodejs -v
v4.2.6

• What did you expect to happen?

both versions should be same.

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH?

• If you are having installation issues, or getting "N/A", what does curl -I --compressed -v https://nodejs.org/dist/ print out?

The issue here is because you installed node with apt - please remove the apt-installed node, and npm, and nodejs-legacy - none of those should ever be on any system.

After that, if you rerun the install script and restart your terminal, what happens?

[reckson]

Thanks for reply. Here's output. node -v v8.11.1
nodejs -v

The program 'nodejs' is currently not installed. You can install it by typing:
sudo apt install nodejs

[ljharb]

@reckson node -v is right, the only thing that calls it nodejs is apt.

OK, so now that you only have an nvm-installed node, what does nvm current print out?

[reckson]

v8.11.1
So there is no need of nodejs apt?

[ljharb]

Zero need, ever.

Looks like you're all set now :-)

Thank you so much =)
