Como executar o Node.js no Mac após instalá-lo com sucesso com gem?

Question

No Mac OSX Yosemite, instalei o nó com êxito:

# sudo gem install node
Fetching: eventmachine-1.0.7.gem (100%)
Building native extensions.  This could take a while...
Successfully installed eventmachine-1.0.7
Fetching: node-0.0.2.gem (100%)
Successfully installed node-0.0.2

E eu vejo isso na lista de gemas instaladas:

# gem list --local

No entanto, quando eu tento usá-lo (o mesmo arquivo app.js roda bem no Windows 7) - o intérprete Node.js não foi encontrado:

# node app.js
-bash: node: command not found
# sudo node app.js
sudo: node: command not found

Além disso, não há um arquivo node em / usr / local / bin .

Por favor me avise, como posso começar a usar o Node.js instalado?

Tenho a sensação de que apenas um pouquinho está faltando aqui.

This gem is a joke with all this hype with the node.js project.

It only includes the eventmachine gem and adds a new alias to it.

executar

sudo apt-get update

sudo apt-get install nodejs

ou

brew update

brew install node
