I have a small project built on python/django. Being very new to web applications and deployment I was very pleased to get it up and running on Railway. This is quite recent, and so used Railpack as the builder. Everything was fine until I added weasy printing to my app. It worked fine on my local linux machine, but when I tried deploying it, I ran into problems. After much reading and experimenting, I found that weasy needs other supporting files that are not installed via pip etc. I found and article that explained which packages were required by weasy and how to load them into a NIXPACK variable. Since this was Railpack, I did more reading and found the variable name RAILPACK_BUILD_APT_PACKAGES, and copied in these package names: libgobject-2.0-0 libcairo2 libpango-1.0-0 libgdk-pixbuf2.0-0 libffi-dev
The build seems to choke on the first package libgobject-2.0-0. I have tried variations on the name, and just can't figure out what needs to happen. If I leave libgobject-2.0-0 out of the list, the build completes, but fails on deployment. If I put it in it fails in the build process.
Does anyone have any ideas?

Hi!
The package you're looking for goes by the name libglib2.0-0. Please check to see if that works. (Note the change in hyphenation)

Hi thanks for that suggestion. It got further, but crashes once deployed. Again the log is attached. Still seems to be tied to locating that one library. libgobject-2.0-0

I believe it's because it's also needed during runtime. Add apt update && apt install libglib2.0-0 && before your current start command, see if that fixes it.

Scratch the above, try setting RAILPACK_DEPLOY_APT_PACKAGES to the exact same value as what you have RAILPACK_BUILD_APT_PACKAGES set to.

I had to add one more library to both lists, but it seems to be working now. THANK YOU for your help!
My final list of libraries is libglib2.0-0 libcairo2 libpango-1.0-0 libgdk-pixbuf2.0-0 libffi-dev libpangoft2-1.0-0
