This buildpack only installs wkhtmltopdf, it isn't very useful by itself. You'll probably want to use it as part of a multi-buildpack. Here is an example using the Ruby buildpack.
$ heroku buildpacks:set 'https://github.com/heroku/heroku-buildpack-multi.git' $ echo 'https://github.com/heroku/heroku-buildpack-ruby.git' >> .buildpacks $ echo 'https://github.com/dscout/wkhtmltopdf-buildpack.git' >> .buildpacks $ git add .buildpacks $ git commit -m 'Add multi-buildpack'
Remember to clean your repository cache if you are updating the version of buildpack. To do that, run:
$ heroku plugins:install https://github.com/heroku/heroku-repo.git $ heroku repo:purge_cache -a appname
If you run into issues when trying to deploy with this buildpack, make sure your app is running on Cedar with Ubuntu 14.04 (
cedar-14). You can check this with:
$ heroku stack
If you are on an older stack, you can upgrade to
$ heroku stack:set cedar-14
