Installing Yeoman - "Yo command not found" - node.js

Question

I have installed node.js and set up npm on my Yosemite install using the npm-g_nosudo script. When I then run npm install -g yo I see a bunch of content scroll through my terminal window, with no errors, and it completes. I then type yo and OS X tells me that it can't find the command.

Running sanity checks on your system
✔ Global configuration file is valid
✔ NODE_PATH matches the npm root
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
Everything looks all right!

Sullys-MacBook-Pro:~ Sully$ yo
-bash: yo: command not found
I also tried using source .bash_profile and rebooting. The command is still not found. Am I doing something wrong?
This is my .bash_profile
# Add environment variable COCOS_CONSOLE_ROOT for cocos2d-x
export COCOS_CONSOLE_ROOT=/Users/Sully/Development/Libraries/cocos2d-x-3.5/tools/cocos2d-console/bin
export PATH=$COCOS_CONSOLE_ROOT:$PATH
# Add environment variable COCOS_TEMPLATES_ROOT for cocos2d-x
export COCOS_TEMPLATES_ROOT=/Users/Sully/Development/Libraries/cocos2d-x-3.5/templates
export PATH=$COCOS_TEMPLATES_ROOT:$PATH
# NPM
export BIN_ROOT=/usr/local/bin
export PATH=$BIN_ROOT:$PATH
This is my full $PATH
Sullys-MacBook-Pro:~ Sully$ echo $PATH
/usr/local/share/npm/bin:/usr/local/bin:/Users/Sully/Development/Libraries/cocos2d-x-3.5/templates:/Users/Sully/Development/Libraries/cocos2d-x-3.5/tools/cocos2d-console/bin:/Users/Sully/.dnx/runtimes/dnx-mono.1.0.0-beta4/bin:/usr/local/bin:/Users/Sully/Development/Libraries/cocos2d-x-3.5/templates:/Users/Sully/Development/Libraries/cocos2d-x-3.5/tools/cocos2d-console/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Answer 1

This was resolved by adding export PATH=/Users/UserAccountName/npm/bin:$PATH to my ~/.bash_profile and restarting Terminal.app.

Answer 2

I have faced the same problem after installing everything succesfully, I resolved it using the following method creating symbolic links to yo, grunt, bower like the following :
For Yo
praveen#praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/yo /usr/bin/yo
For Grunt
praveen#praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/grunt /usr/bin/grunt
For Bower
praveen#praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/bower /usr/bin/bower
Here in the above commands the common path /home/praveen/.npm-global/bin/ may change according to your system folder structure.
