npm error code ENOTCACHED
npm error request to https://registry.npmjs.org/confbox failed: cache mode is 'only-if-cached' but no cached response is available.
npm error Log files were not written due to an error writing to the directory: /nix/store/sz4fx9zypkd141k5a594b7axalmqp900-9router-0.5.95-npm-deps/_logs
npm error You can rerun the command with `--loglevel=verbose` to see the logs in your terminal

ERROR: npm failed to install dependencies

Here are a few things you can try, depending on the error:
1. Set `npmDepsFetcherVersion = 2` (and update `npmDepsHash`)
2. Set `makeCacheWritable = true`
  Note that this won't help if npm is complaining about not being able to write to the logs directory -- look above that for the actual error.
3. Set `npmFlags = [ "--legacy-peer-deps" ]`
