permission denied error with nix-shell example

The shellHook in the nix-shell example fails with :

npm WARN checkPermissions Missing write access to /home/ngyj/source/tests/bs-tea-starter-kit/node_modules/bs-platform

Either I need to run as root (which I'm not up to) or it tries write in that directory (which will never succeed since it's a symlink to the nix store).

Are you sure the version of bs-platform your project depends on (in package.json) is the same version you install with nix? I think the error is npm/yarn trying to overwrite the symlink so effectively undo the nix install. This should not happen would the version be compatible I believe.
