// Sometimes this will throw an error along these lines
gyp ERR! stack Error: `make` failed with exit code: 2

// The most likely thing is that the version of node-sass installed on your project is incompatible to your version of Node

// To fix this, visit to confirm whether this is the case. If so, install n (the interactive version manager) by running:

npm install -g n
// make cache folder (if missing) and take ownership
sudo mkdir -p /usr/local/n
sudo chown -R $(whoami) /usr/local/n

// Install the appropriate version of node
n 10.16.0

n lts // for the most recent stable release with long term support

// If it throws a sudo error along these lines,

Error: sudo required (or change ownership, or define N_PREFIX)
