env: node: No such file or directory in mac

I'm searching it in google on how to show the version of node js or how I'm gonna work with npm? If I do this

npm -v

even I already install it using brew install node. The result is always

env: node: No such file or directory

I already do a lot of command to solve for it, but failed. these are the command that I already try:

sudo apt-get install nodejs-legacy
sudo ln -s /usr/local/bin/node /usr/bin/node
brew unlink node
brew link node

I can't start the task because of this. help me guys. This work before after I used this command brew link --overwrite node. Now I have problem, i cant work anymore with npm.
