Recently when I was trying to run my application on an ubuntu virtual server, I kept getting the error
npm command not found even though I had installed nvm an node.
Based on my searches it seems like if you have installed nvm as a regular user, you wont be able to execute the nvm command with sudo.
The only painless way i could find to run nvm with sudo is by installing nvm using sudo itself through the following command
wget -qO- https://raw.githubusercontent.com/xtuple/nvm/master/install.sh | sudo bash
Here’s the git repo that proposed the above command as a solution.
