I got stuck when trying to install the mediainfo package through
apt install mediainfo. Using buildpacks failed and the solution was to use heroku-buildpack-apt.
3rd party build packs
Search the 3rd party Heroku buildpacks to find if someone has already created a buildpack for your Linux package.
There were plenty of options for MediaInfo. I chose one and ran this command in the Heroku CLI:
heroku buildpacks:add https://github.com/bubobox/heroku-buildpack-mediainfo -a <app>
Make sure you re-release your app so changes take place. The fastest way to do that is to add an environment variable to your app and Heroku will automatically re-release it.
Go to Settings => Config Vars => Reveal Config Vars
This approach failed with the following error as I tried to run MediaInfo in the Rails console:
I got this error:
version `CURL_OPENSSL_3' not found (required by /app/vendor/mediainfo/mediainfo)
I tried other buildpacks but the same error came up. I suspect it’s because the available buildpacks haven’t been updated in a while. I didn’t want to write my own buildpack.
Install the MediaInfo package yourself by using the heroku-buildpack-apt buildpack.
Add this buildpack from the Heroku CLI:
heroku buildpacks:add --index 1 heroku-community/apt
Create a file named
Aptfile and add a package name on each new line that you want Heroku to automatically add to your application. In my case, I wanted
mediainfo apt package.
# AptFile # You can write comments in this file. mediainfo
Redeploy your app to Heroku and try out MediaInfo in the Rails Console again. It worked for me.
