Make sure Node.js and NPM are up to date. If not, then run the following:

Get the latest node.js (to keep ng2 CLI happy).

nvm install node

nvm use 7.5.0 or whichever is the latest at the time.

Update npm.

npm install -g npm

Then run npm install to install dependencies.

Run ng serve --host 0.0.0.0 --port 8080 --live-reload-port 8081 for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files. If you need to change ports and such, use ng serve --host 0.0.0.0 --port 8080 --live-reload-port 8081 and then navigate to http://localhost:8080/ to view the site.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.
