Failing precompilation for DecisionTree

Hey Julia community,

For the past few months, the command using DecisionTree (as well as using MLJDecisionTreeInterface) has been met with the error message below on my machine. These packages previously worked fine for me—I have no idea what changed. I suspect I’m missing something basic about how packages are managed.

I’d be grateful for any advice! I’m also including the outputs from versioninfo() and ]st below. Please let me know if I should include anything else, or if I ought to post this under a different topic.

Info Packages marked with ⌃ and ⌅ have new versions available, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated`

Can you try Julia 1.9.1 and the latest DecisionTree version (0.12.3)?

On a general note, you are making the classic mistake of having a very crowded global environment which will almost guarantee version conflicts and packages being held back (e.g. I see DataFrames at version 1.3.6 when the latest is 1.5). Don’t do this, work in project-specific environments instead to which you only add the packages you need for whatever you are working on.

@nilshg You’re absolutely right, thank you! I was worried my package mismanagement would get me in trouble someday.

For anyone who stumbles upon this thread in the future, here’s a soft introduction to setting up project environments: How to setup Project Environments in Julia | by René | Towards Data Science

Thanks again,
