I am trying to run another NodeJS version with nvm but getting this error:
$ nvm use v4.2.4 nvm is not compatible with the npm config "prefix" option: currently set to "/Users/z/.npm-global" Run `npm config delete prefix` or `nvm use --delete-prefix v4.2.4` to unset it. I have my prefix set on purpose to avoid sudo npm (see https://docs.npmjs.com/getting-started/fixing-npm-permissions).
Is there any way I can use nvm without losing my prefix for globally installed packages?

Node Version Manager, more commonly called nvm, is the most popular way to install multiple versions of Node.js, but is only available for Mac/Linux and not supported on Windows. Instead, we recommend installing nvm-windows and then using it to install Node.js and Node Package Manager (npm).
This is the closest parent directory to contain a package. json file or node_modules directory, unless -g is also specified. If -g is specified, this will be the value of the global prefix. See npm config for more detail.
nvm (Node Version Manager) is a tool that allows you to download and install Node. js. Check if you have it installed via nvm --version . curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.26.1/install.sh | bash. npm (Node Package Manager) is a tool that allows you to install javascript packages.
$ npm config delete prefix $ npm config set prefix $NVM_DIR/versions/node/v6.11.1 Note: Change the version number with the one indicated in the error message.
nvm is not compatible with the npm config "prefix" option: currently set to "/usr/local" Run "npm config delete prefix" or "nvm use --delete-prefix v6.11.1 --silent" to unset it.
