Outdated dependencies

[eliasab16]

Hi, it seems like the dependencies are outdated. I tried running npm i but I keep having issues with node-gyp. I received error messages saying that node-gyp has a bug and should be updated. But doing so doesn't fix the issue and errors keep showing up. Could you please look into the issue or update the repo? For now, it's impossible for me to use the sourcecode, which makes it really hard to follow along with the book.
