New to managing package dependencies and environments

New to Julia

Hi. I don’t really understand very well how to set up the project.toml file for my package - in particular I don’t understand how to set up package dependencies or use environments. So I have two questions. First, can anyone tell me how to fix the following dependencies problem (see below), and second, where can I find a Packages for Dummies reference to read up on all this?
Thanks!

The toml files will be set up for you by the package manager (except for optional but recommended dependency compatibility bounds). Once you generate a package and activate it as the current environment, then packages you add to that environment will automatically become dependencies of your package.

Thanks very much, @Nathan_Boyer - that’s really useful information. I’m still struggling to understand where to start with solving the precompilation problems of GLMakie and DynamicalSystems. If it helps, their compatibilities are:

Agents = "5.8.0, 6"
CSV = "0.10"
DataFrames = "1.5.0"
DynamicalSystems = "3.0.0"
GLMakie = "0.8.2, 0.9"
InteractiveDynamics = "0.22"
Makie = "0.19.2, 0.20"
Observables = "0.5.4"
Statistics = "1"
julia = "1.6"

I notice the error message says Julia 1.12. Why are you running the nightly version? Use Julia 1.10.2.

Thanks. So if I understand you rightly, I should either remove the nightly run or change it to use version 1.10.2, yes? How would I do either of those? So far, I’ve just let github do whatever it throught best. :face_with_diagonal_mouth:

OK, got it! I removed the nightly run from CI.yml. But I really must start trying to understand all this job control stuff better. Thanks for your help! :smiley:

Oh, I did not know this is for continuous integration. For a packge of this complexity, it might be some time before Julia nightly is fully compatible with these packages. It’s not a bad idea to add an optional test for this though.

You know, as a beginner - and maybe even more so as someone who is knowledgeable in one area and not in another - it’s not easy to come out and tell others what one doesn’t understand. Because of this, I just love the friendly, helpful and thoughtful atmosphere here on the julia discourse forum. Thank-you very much! :smiley:
