ExprSplitter not defined

[AsafManela]

I keep getting these errors after changing a file within a module (InfoVal).
Upgrading to Revise 3.1.1 did not help (I was on the revise3 branch before).
Any thoughts?

You must be changing environments somewhere in your workflow (JuliaLang/julia#35663), otherwise this would not be possible. ExprSplitter is implemented in JuliaInterpreter 0.8; you must have some environment that is still on v0.7.

Yep. I mistakenly thought that because Revise is loaded from my main 1.5 environment using the startup script that it used its JuliaInterpreter, but as you suspected, when it switched to my project it had an older JuliaInterpreter in its manifest.
Updating that project solved the issue.

Thanks for the quick response!

This just bit me too, on Julia 1.6 with Revise 2.7.6. I was using a different environment from the base Julia environment, and the environment I was using didn't have Revise in Project.toml. Yet, julia --project="@." in the project dir allowed me to type using Revise without issue, and then subsequent changes I made to a file in the project would lead to the warning in this issue. This kind of feels like a footgun, although I'm not even sure how I managed to load Revise in the REPL when I hadn't included it as a project dependency.
