Bower, Grunt & zsh: command not found:

When you installed, did you install globally?

npm install -g bower

give that a try. If not, also try adding sudo

sudo npm install -g bower

I couldn't get the above to work. Problem was that I had just reinstalled my Mac and forgotten to re-install grunt.

You can test that grunt is actually installed and working properly outside of zshell by going back to bash with bash -l and running grunt.

If grunt is throwing the same error you can install grunt by running:

sudo npm install -g grunt-cli 

Run zsh to get back to zshell.

When you install grunt (bower), terminal tell you directory. For those using a ZSH shell, add this to .zshrc:

export PATH=/usr/you/directory/npm/bin:$PATH,

I find it using:

/lib/node_modules
export PATH=/usr/lib/node_modules/npm/bin:$PATH

Add /usr/local/share/npm/bin/ to your $PATH environment
