Points: # - when build is run in the original repo, no specific executable seems to be generated; you run the resulting build with pnpm run start # - this means we need to add a dedicated script - perhaps it is possible to create this from the workers-sdk dir, but I don't know how to do this # - the build process builds a version of miniflare which is used by wrangler; for this reason, the miniflare package is copied also # - pnpm stores all content in the top-level node_modules directory, but it is linked to from a node_modules directory inside wrangler # - as they are linked via symlinks, the relative location of them on the filesystem should be maintained installPhase = '' runHook preInstall mkdir -p $out/bin $out/lib $out/lib/packages/wrangler rm -rf node_modules/typescript node_modules/eslint node_modules/prettier node_modules/bin node_modules/.bin node_modules/**/bin node_modules/**/.bin cp -r node_modules $out/lib cp -r packages/miniflare $out/lib/packages cp -r packages/workers-tsconfig $out/lib/packages cp -r packages/wrangler/node_modules $out/lib/packages/wrangler cp -r packages/wrangler/templates $out/lib/packages/wrangler cp -r packages/wrangler/wrangler-dist $out/lib/packages/wrangler rm -rf $out/lib/**/bin $out/lib/**/.bin cp -r packages/wrangler/bin $out/lib/packages/wrangler NODE_PATH_ARRAY=( "$out/lib/node_modules" "$out/lib/packages/wrangler/node_modules" ) makeWrapper ${lib.getExe nodejs} $out/bin/wrangler  --inherit-argv0  --prefix-each NODE_PATH : "$${NODE_PATH_ARRAY[@]}"  --add-flags $out/lib/packages/wrangler/bin/wrangler.js runHook postInstall ''; meta = { description = "Command-line interface for all things Cloudflare Workers"; homepage = "https://github.com/cloudflare/workers-sdk#readme"; license = with lib.licenses; [ mit apsl20 ]; maintainers = with lib.maintainers; [ seanrmurphy dezren39 ]; mainProgram = "wrangler"; # cpp is required for building workerd. # workerd is used for some wrangler subcommands. # non-linux platforms may experience errors # on certain subcommands due to this issue. platforms = [ "x86_64-linux" ]; }; }) </ins>

Discussion:
Steps to reproduce the behavior: nixos flake build, with nixpkgs/master, which worked yesterday and doesn't today fails on workerd fixed derivation that is pulled from npm may relate to based on commit histor <!-- Please @ people who are in the list of the offending package or module. If in doubt, check for whoever last touched something. --Please run and paste the result. I do have a bunch of experimental flags enabled, they could impact something..
