Start by reading Makefile, especially the build target and its reference to node_modules/@mathieudutour/js-fatigue/Makefile. Reproduce the failure with npm i -S sketch-module-json-sync/ and inspect the attached npm debug log. Done means the package installation and prepublish build complete without the missing-file error.
