Hi Jelle, I tried to import jquery with the last version of your code
This is the resulting expression (they are a lot, this is just one) (define-public node-jquery (package (name "node-jquery") (version "3.1.0") (source (origin (method url-fetch) (uri " https://github.com/jquery/jquery/archive/3.1.0/jquery-3.1.0.tar.gz") (sha256 (base32 "05jcaa0xg041hpq3xdswf45jbkm6shvinjm3scawwjqqlrc39xca")))) (build-system node-build-system) (propagated-inputs `()) (native-inputs `()) (synopsis "JavaScript library for DOM operations") (description "JavaScript library for DOM operations") (home-page "https://jquery.com") (license expat))) As you can see, there are no native-inputs I understand that dev-dependencies (as on line 467) is used by make-npm-sexp to populate native-inputs, so in the terminal I inspected dev-dependencies expecting to find it empty and I was wrong, it was correctly populated Like this ("node-native-promise-only" "node-insight" "node-strip-json-comments" "node-cross-spawn" "node-q" "node-grunt-git-authors" "node-grunt-contrib-watch" "node-eslint-config-jquery" "node-husky" "node-load-grunt-tasks" "node-qunitjs" "node-sinon" "node-commitplease" "node-grunt-eslint" "node-sizzle" "node-grunt-babel" "node-jsdom" "node-babel-preset-es2015" "node-grunt-npmcopy" "node-grunt-contrib-uglify" "node-gzip-js" "node-qunit-assert-step" "node-requirejs" "node-grunt" "node-promises-aplus-tests" "node-grunt-compare-size" "node-grunt-jsonlint" "node-testswarm" "node-core-js" "node-grunt-cli" "node-grunt-newer") So now I can't explain why native-inputs is empty. Maybe I should run this a few times to ensure that the result is always the same But this could be worth your attention.
