nvm: Manjaro: `nvm is not compatible with the npm config "prefix" option: currently set to ""`

All of a sudden nvm stopped working 😦 I’ve done a clean install of nvm. It goes well. Then when I do nvm install lts/dubnium I get the following error.

nvm is not compatible with the npm config "prefix" option: currently set to ""
Run `npm config delete prefix` or `nvm use --delete-prefix v10.15.0` to unset it.

Since, lts/dubnium was successfully installed, I also tried nvm use lts/dubnium I get the same error.

If I run nvm use --delete-prefix v10.15.0, then the system node get used, and I cannot get it to use lts/dubnium.

There is no .npmrc file. I use zsh.

• How did you install nvm? (e.g. install script in readme, Homebrew):

• What steps did you perform? What happened?

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

which worked great.

Then I ran nvm install lts/dubnium resulting in

=> If you wish to uninstall them at a later point (or re-install them under your

     $ nvm use system

=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

which installed the v10.15.0, but gave the error
