Can't install nimble_parsec

Questions / Help
1

I am trying to use nimble_parsec (GitHub - dashbitco/nimble_parsec: A simple and fast library for text-based parser combinators) in my livebook via Mix.install. Unfortunately it times out during execution and lands me back to the livebook index page.

I created the machine using Livebook · Launch on Fly.io. Can I add the dependancy via the command line somehow? Do I need to scale up the server from the free tier?

Scaling the memory of the app from 256MB to 512MB ram fixed the issue. I guess that is going to take me out of the free tier though. Scaling back down to 256MB afterward seems to reset the app and puts me back to square 1 unfortunately.

We’re working on enabling swap via a setting, but in the meantime you can do it on your own in an entry point before your main command.

Thanks for the suggestion, unfortunately because I created the app using the “Launch on Fly.io” link for Livebook I don’t have a local copy and have no idea how to edit the dockerfile. I have looked on the docs for flyctl but don’t see anything obvious. Is there someway to git clone my own launched app?
