Error: nvm already installed.

I've previosuly had installed nvm using fisher install jorgebucaran/nvm.fish (which now is removed).
I've removed the .nvm folder together with the $NVM_DIR.

What's left?

You need to install nvm separately to be able to use this plugin, see nvm-sh/nvm/README.md#install-script for instructions.

Then check out the usage section for how to set your $NVM_DIR (if you have a custom one).
