Topic: Lean Copilot setup issue: no .Olean file created

Hi All,

Been trying to get Lean Copilot up & running in VSCode with the Lean 4 plugin on Linux.

My install is successful; everything is in the correct directory structure; my lakefile.toml is all good; I’ve run lake update & lake build successfully. Great!

yet the import LeanCopilot fails spectacularly, apparently due to the lack of an .olean file. :hmm:

I’ve been talking to Peiyang Song here: https://github.com/lean-dojo/LeanCopilot/discussions/180 & he’s super-helpful!

Does anyone here also have any ideas for getting the .olean file created so the import will be successful?

Thanks in advance for tips, tricks & insights.
