However if jinja isn't available trying to build a site with this theme will show no errors/warnings, only copying some assets will not happen.\r\n\r\nTo reproduce: \r\n* install nikola in an empty virtual environment\r\n* make a demo site\r\n* switch theme to bootstrap3-jinja\r\n* build & serve\r\n\r\nSilent build error is very hard to pin down, and therefore I believe this is a bug."}}
