Fails trying to link executable while doing a `npm install`

[paulvictor]

I am trying to use node2nix to build nativefier using node2nix, as a intermediate step with which I thought of building other web based applications(gmail, slack ...). I am using home-manager to manage all my packages in the config and so modified the generated default.nix and node-env.nix (its no more a set with 3 attrs but the derivation of the nodePackage). While trying to install, the build fails with

npm info it worked if it ends with ok npm verb cli [ '/nix/store/av48vw9bj89j9iz7736i1zyz6g2yzzs1-nodejs-10.12.0/bin/node', npm verb cli '/nix/store/av48vw9bj89j9iz7736i1zyz6g2yzzs1-nodejs-10.12.0/bin/npm', npm verb cli '-dd', npm verb cli '--offline', npm verb cli '--nodedir=/nix/store/jii1y9cvasbyrn8qccqp2p9sw167mdl3-node-sources', npm verb cli '--production', npm verb cli 'install' ] npm info using [email protected] npm info using [email protected] npm verb npm-session 1ca0ab8bf6cbe337 npm info lifecycle [email protected]~preinstall: [email protected] npm timing stage:loadCurrentTree Completed in 448ms npm timing stage:loadIdealTree:cloneCurrentTree Completed in 2ms npm timing stage:loadIdealTree:loadShrinkwrap Completed in 58ms npm timing stage:loadIdealTree:loadAllDepsIntoIdealTree Completed in 254ms npm timing stage:loadIdealTree Completed in 374ms npm timing stage:generateActionsToTake Completed in 22ms npm verb correctMkdir /build/.npm/_locks correctMkdir not in flight; initializing npm verb makeDirectory /build/.npm/_locks creation not in flight; initializing npm timing audit compress Completed in 5ms npm info audit Submitting payload of 5313bytes npm verb lock using /build/.npm/_locks/staging-79326044fbe75152.lock for /nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier/node_modules/.staging npm verb unlock done using /build/.npm/_locks/staging-79326044fbe75152.lock for /nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier/node_modules/.staging npm timing stage:executeActions Completed in 40ms npm timing stage:rollbackFailedOptional Completed in 0ms npm info linkStuff [email protected] npm verb linkBins [ { nativefier: 'lib/cli.js' }, npm verb linkBins '/nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/.bin', npm verb linkBins false ] npm verb stack Error: ENOENT: no such file or directory, chmod '/nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier/lib/cli.js' npm verb cwd /nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier npm verb Linux 4.19.12 npm verb argv "/nix/store/av48vw9bj89j9iz7736i1zyz6g2yzzs1-nodejs-10.12.0/bin/node" "/nix/store/av48vw9bj89j9iz7736i1zyz6g2yzzs1-nodejs-10.12.0/bin/npm" "-dd" "--offline" "--nodedir=/nix/store/jii1y9cvasbyrn8qccqp2p9sw167mdl3-node-sources" "--production" "install" npm verb node v10.12.0 npm verb npm v6.4.1 npm ERR! path /nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier/lib/cli.js npm ERR! code ENOENT npm ERR! errno -2 npm ERR! syscall chmod npm ERR! enoent ENOENT: no such file or directory, chmod '/nix/store/cj7912mr3cysfg5cg1q99dzdzxsm0y14-node-nativefier-7.6.10/lib/node_modules/nativefier/lib/cli.js' npm ERR! enoent This is related to npm not being able to find a file.

I can see from the package.json file that the npm script build is the one which generates the lib/cli.js (verfied by manually running npm run build ).

So 2 things,

1. Why does npm install try to link something which is not there when I am just trying to install dependencies?
2. How do I enable that extra step gulp build?

I am using nodejs-10.

Thanks

I've figured out the issue. I had to do a gulp build after the npm install (with dev dependencies) which I didn't do in the previous step and then link the binaries. So wrote a postInstall hook for the same. Was wondering if the same can be incorporated in the install phase by adding a hook after the npm install but before the linking of executables?

@paulvictor Do you mind explaining in more detail what you did which allowed the build to run? Currently, Im trying to build nativefier from the github repo (not npm) and I am getting a similar error. So far, ive tried overriding the prebuild and preInstall phases to include npm run build but it has had no effect on the build process
