How did you install nvm?

Yes, I have already installed nvm through the shell command from the readme file

What steps did you perform?

Use the function load_nvm for the fish shell

What happened?

When I navigate between my folders through shell the function load_nvm for the fish shell is invoked, so this function doesn't work correctly when using the following command nvm version because the alias is returned instead of the real version (for example v14.19.0) this provokes that each update in $PWD the nvm use default it's called

What did you expect to happen?

The load_nvm function evaluates correctly the current version

The proposed solution that works for me

# On ~/.config/fish/functions/load_nvm.fish
set -l node_version (nvm version (nvm current))

Is there anything in any of your profile files that modifies the PATH?

If you are having installation issues, or getting "N/A", what does curl -I --compressed -v https://nodejs.org/dist/ print out?

```sh ```

I don't use fish, so I'm not sure what to do here - this was added in #2208 by @jaredramirez. Maybe they can shed some light?

On ~/.config/fish/functions/load_nvm.fish

set -l node_version (nvm version (nvm current))
