I am running the following on NixOS:
$ npm install express-generator -g
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
npm ERR! code EROFS
npm ERR! syscall mkdir

It fails, and adding sudo doesn't help (isn't it saying read only):
$ sudo npm install express-generator -g

Thanks.
