Sage is tested on Travis CI with every commit to make sure that npm install, bower install, and gulp all work properly. Bugs can still pop up, but usually there’s something wrong with your environment if you can’t get things running.
If you’re running into problems, first make sure that your development environment meets the minimum requirements:
- Node.js >= 4.5.0
- gulp >= 3.8.10
- Bower >= 1.3.12
Ensure you’re using the latest version of npm: npm install -g npm@latest
Then run npm cache clear && rm -rf node_modules && npm install from your theme directory. You might want to run it and make a note of the errors you’re getting, if any.
Let us know what versions of things you’re running by typing node -v && npm -v && gulp -v
