1) How to install NVM on the Jenkins Slave?
2) How can we make the jobs to use that NVM so that we can install multiple NodeJS / NPM version?
Note: I am trying to follow this URL: https://github.com/nvm-sh/nvm/blob/master/README.md#install--update-script but not able to understand as how it can be done on Jenkins and make use of the job to use NVM.
Note: I can't use NVM Wrapper or NodeJs as I don't have Manage Jenkins Permissions.
