Follow the instructions on the nvm repository on GitHub.


To install a version of node:

->      v8.10.0  
default -> v8.10.0
node -> stable (-> v10.16.2) (default)
stable -> 10.16 (-> v10.16.2) (default)
iojs -> N/A (default)
lts/* -> lts/argon (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.16.1 (-> N/A)

To switch to another node version:

nvm use 10.16.3

To check which version is set as the default:

nvm alias default

To set another version as the default version:

nvm alias default 6.17.1

If you are done with a node version and want it gone, use the uninstall command:

nvm uninstall 4.9.1

Working with different node versions for different projects is a breeze when using nvm, which will take care of everything you need to manage regarding nodejs versions.
