The Problem
If you installed nodejs using the node version manager. i.e. nvm its possible that if you upgrade your version of node using nvm install you will end up with the following errors when running a git commit(which ran several grunt tasks like jshint etc)
/usr/bin/env: node: No such file or directory
The resolution is to update your softlink as follows
The Resolution
If you are running an ubuntu machine, this should help
sudo rm /usr/bin/node
sudo ln -s /usr/bin/nodejs /usr/bin/node
