I successfully created a spine app as explained on spine\'s Getting started page. However, hem doesn\'t automatically take my changes into account ; I have to build manually
Hem 0.1.9 (the latest version) is not automatically detecting changes to my spine app when running "hem server"(although "hem watch" seems to be working correctly). I was able to get it working by uninstalling 0.1.9 (npm uninstall -g hem) and installing 0.1.8 instead (npm install -g hem@0.1.8).
Regarding your other issue, spine/lib/tmpl is no longer included in the latest version of spine, so if you want to use the screencast you'll need to install whatever version of spine he is using.
