Solutionsource: stackoverflow \u2197

I guess you did not have the make tools available when you installed your mongodb library. I suggest you do xcode-select --install (on a mac) or sudo apt-get install gcc make build-essential (on ubuntu) and run rm -rf node_modules npm cache clean npm install OR just npm update based on @tobias comment (after installing build-essential) npm update
