Good old node-gyp. I have absolutely no idea what it even is but it has been giving me errors for what feels like a decade. Mostly via front end build stuff from various projects I have worked on
if you want to know, it's a fork of google gyp, which is a C/C++ project/build system generator. I.e. it's a bit similar to CMAKE, a tool to describe native code projects and what needs to be built in order to make executables and dlls.
It's a python codebase, largely abandoned by google. They used to use it for building Chrome.
