Cannot install ember on ubuntu 1404

I installed nodejs and npm on my ubuntu. After then i installed ember on my machine and i type ember -v to verify that ember has installed successfully.But terminal says;

/usr/bin/env: node: No such file or directory

I accidently install node (instead of nodejs) but i remove it..now if i type node in terminal and enter,it says;

The program 'node' can be found in the following packages:

 * node

 * nodejs-legacy
Try: apt-get install <selected package>

what I have to do to install ember properly??? Thank you!!!
