Additionally, running gulp setcap, which runs a script that is supposed to make this operation permissible to the current user, does not work.

See https://github.com/teampizza/backpack/blob/devel/backend/parser/cap_permission.sh for the script used.

Note that if nvm is running in a different shell than the one you have configured, the permissions setting will not be able to find that executable since the environment vars are different ($NVM_BIN will not exist, for example). This happens if you run fish and is something I need to figure out.
