Installation nvm in Ubuntu 14.04

Question

I have to install nvm on Ubuntu 14.04 for a work and this is the guide that I have to follow:

Installation of nvm globally

1. sudo git clone https://github.com/creationix/nvm.git /opt/nvm
2. sudo mkdir /usr/local/nvm
3. sudo addgroup -system dev
4. sudo chown -R root:dev /usr/local/nvm
5. sudo chmod -R 775 /usr/local/nvm
6. sudo vim /etc/profile.d/nvm.sh

Installation of node v 4.x

7. sudo mkdir /usr/local/node
8. sudo chown -R root:dev /usr/local/node
9. sudo chmod -R 775 /usr/local/node
10. nvm stable

The problems are that in the passage 6 I don't know exactly what to do or write in the file nvm.sh and then the last command tells me "nvm: command not found"

Answer 1

you should add to nvm.sh the following content:

export NVM_DIR=/usr/local/nvm
source /opt/nvm/nvm.sh

export NPM_CONFIG_PREFIX=/usr/local/node
export PATH="/usr/local/node/bin:$PATH"
