First of all, remove node completely

 $ rm -rf ~/.npm ~/.nvm 

Use NVM to control node version ...

 $ curl https://raw.githubusercontent.com/creationix/nvm/v0.17.1/install.sh | bash $ source ~/.nvm/nvm.sh //add this line to my ~/.bashrc, ~/.profile, or ~/.zshrc 

Adding a source to a profile using nano:

$ nano ~/.profile

Down to the end of the file and add this line:

source ~/.nvm/nvm.sh

Then hit CTR+X and press Y to save the same for others ...

Use a stable version of node

 $ nvm install 0.10.32 $ nvm use 0.10.32 $ nvm alias default 0.10.32 

Once you have installed Node, you will need to install Ember CLI globally with

 $ npm install -g ember-cli 

This will give you access to the ember command prompt.

You need to install Bower, a package manager that supports your external interfaces (including jQuery, Ember, and QUnit). It is as simple as running:

 $ npm install -g bower 

This will give you access to the bower command line runner.

Now you can run the enberCLI commands.
