echo 'export PATH=$PATH:$HOME/.nodebrew/current/bin' >> ~/.bash_profile

Install node.js

Before you install node.js, check the latest version of node.js on official website.

You might find out 2 or more versions of node.js.
I recommend you to install LTS(Long Term Support) version.

If you decided the version, type below and you can see all versions you can install.

nodebrew ls-remote

Can you find out the version you want? O.K. Let's install it.

nodebrew install-binary <THE-VERSION-YOU-WANT>

Please replace the to the version you want to install.

If you get error like below,

Warning: Failed to create the file 
Warning: /Users/<YOUR-USER-NAME>/.nodebrew/src/v8.9.3/node-v8.9.3-darwin-x64.tar.gz: No

Make the folder which is needed with this command.

mkdir -p ~/.nodebrew/src

and retry nodebrew install-binary <THE-VERSION-YOU-WANT>

Launch node.js

Before launching node.js, check the nodebrew.

nodebrew ls

You can get like below:
