New to node and need to install npm, node.js? Use NVM node version manager so you can install more than one version of nodejs.
I had to look for the answer to this until I found it. You update to a newer version of NVM node version manager the same way you install it regardless of how you install it. I am not sure what happens if you install nvm with curl then try to update it in another way.
For example I used the following in my terminal as not the root user, just a plain user
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
When I want to install the next version I replace the v0.35.3 with the next version and it does all the work. If you installed nvm as a root user then you will not be able to access it easily as any other user.
In fact, if you type nvm –version in the command line as a regular user after you installed it as a root user, you will be told it is not installed, or nvm is not a recognized command would you like to install. I did this, so that is how I learned not to install it as a root user.
If you are using windows you can install nvm by following these instructions
