Fish shell, nvm, is telling me that node and npm are "currently not installed" but they are

Question

I'm having a problem with npm and node, using the fish shell, following a recent update of fish, fisher, bass and nvm on OS X Big Sur.

$ node -v

type: Invalid combination of options
Fish nvm: 'node' is currently not installed, try running npm i -g node

$ npm -v

type: Invalid combination of options
Fish nvm: 'npm' is currently not installed, try running npm i -g npm

NVM seems to be working fine:

$ nvm list

->     v10.16.0
        v12.4.0
       v12.16.1
       v13.11.0
       v14.16.0
         system
default -> 10.16.0 (-> v10.16.0)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v14.16.0) (default)
stable -> 14.16 (-> v14.16.0) (default)
lts/* -> lts/fermium (-> v14.16.0)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.0 (-> N/A)
lts/erbium -> v12.21.0 (-> N/A)
lts/fermium -> v14.16.0

It successfully switches node versions.

$ nvm use v14 Now using node v14.16.0 (npm v6.14.11)

$ which node /Users/brianfogel/.nvm/versions/node/v14.16.0/bin/node

$ which npm /Users/brianfogel/.nvm/versions/node/v14.16.0/bin/npm

For additional context here are some other things that might be helpful to show:

$ fish --version fish, version 3.2.0

$ fisher --version fisher, version 4.2.0

$ nvm -v 0.37.2

end

function npm -d "node package manager" -w npm
  __nvm_run "npm" $argv
end

$ cat ~/.config/fish/functions/nvm.fish

function nvm
  if not type -q bass
    echo 'Bass is not installed please install it running fisher edc/bass'
    return
  end
  set -q NVM_DIR; or set -gx NVM_DIR ~/.nvm
  set -q nvm_prefix; or set -gx nvm_prefix $NVM_DIR
  
  bass source $nvm_prefix/nvm.sh --no-use ';' nvm $argv

  set bstatus $status

  if test $bstatus -gt 0
    return $bstatus
  end

  if test (count $argv) -lt 1
    return 0
  end

  if test $argv[1] = "use"; or test $argv[1] = "install"
    set -g NVM_HAS_RUN 1

$ cat /usr/local/bin/npm

$ $ set --show fish_user_paths

https://github.com/FabioAntunes/fish-nvm has been updated. Installing or updating the plugin fixes the problem.
