Install npm

sudo npm install npm -g

brew install npm

inside the project directory

run:

npm install

The command above should have installed the packages:

• gulp
• gulp-concat
• gulp-connect
• gulp-open

If you you can install them manually by running:

npm install gulp gulp-concat gulp-connect gulp-open

run:

gulp

This will create a dist/ folder inside app/ containing both css/ and js/ concatenated files.

If for any reason, those folders or files are not created, you could manually run:

gulp css

or

gulp js

To generate those directories manually.
