-Both methods have in common that they are setting the correct environment for using npm inside Homebrew and are returning the arguments for invoking `npm install` for their specific use cases. This includes fixing an important edge case with the npm cache (caused by Homebrew's redirection of `$HOME` during the build and test process) by using our own custom `npm_cache` inside `HOMEBREW_CACHE`, which would otherwise result in very long build times and high disk space usage.
