Rails-ShareTribe. Error on npm install (ubuntu 16.04) - ruby-on-rails

Question

I'm very beginner on Ruby and Ruby on Rails and i just managed to install RonR my server. My problem is, when i try to install a platform called ShareTribe, although everything went just fine until bunde install , npm install came with this error:
npm ERR! Linux 4.4.0-21-generic

What i realized is that My os causes that (Darwin aka. Mac OSX is the valid os)
Is my guess right? If yes, is there any way to install the platform on Ubuntu?
If not, how can i correct this error?
Thank you in advance!

You must install all the requirement within the same version
make sure your npm path is registered, you can use the following
export PATH="/Users/{YOUR_USER_NAME}/.npm-packages/bin/:$PATH"
now you can install nvm using the following code
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.9/install.sh | bash
and write the following to load the NVM and set the required version for sharetribe
export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" && nvm alias default 7.8.0
Hope this would help
