How to fix an issue installing Node `canvas` on macOS

How to fix a node-pre-gyp install issue installing the Node.js canvas library on macOS

I wanted to use the Node.js canvas NPM package but running npm install canvas failed with messages like this:

npm ERR! code 1
npm ERR! path /Users/flaviocopes/dev/old/generate-images-posts/node_modules/canvas
npm ERR! command failed

To fix this, I ran:

brew install pkg-config cairo pango libpng jpeg giflib librsvg 

and npm install canvas worked fine!
