If you got the problem of installation yeoman in ubuntu 14, it’s better to read this blog:
By Andreas Vlachos :
In Ubuntu 14.04 (actually starting from 13.10) versions 0.10.x of nodejs are present in the official repositories. So in order to install nodejs package manager just type:
sudo apt-get install npm nodejs-legacy
npm alone is not sufficient to install Yeoman, since the latter depends on ‘node’ legacy binary during installation, hence nodejs-legacy package is also required.
Install global npm packages as a regular user.
npm installs packages under a ‘prefix’ configuration variable, which defaults to /usr/lib in Ubuntu 14.04. In order to avoid using sudo for every npm-install command, you may configure ‘prefix’ variable to point into a user local directory.
sudo npm set prefix '$HOME/[your_npm_directory]' --global
Verify that setting has been set using; defaults to /usr/lib
sudo npm get prefix
Update your $PATH variable to include the location npm installs binaries,
echo "export PATH=$PATH:$HOME/dev/npm/bin" >> $HOME/.profile
and restart your terminal session.
Install Yeoman :
npm install -g yo
as mentioned in the official site.
Install angularJS generator
npm install -g generator-angular
Generate angularJS application
Invoke grunt to build the application grunt serve (or python -m SimpleHTTPServer) to preview the application.
