Hi,
I tried to precompile MultiJump package on my julia version 1.1.1.1 and JuMP package version v0.19.2 but it fails with the following report. Any idea how to solve this issue?

Iām sure the versions have changed since this post, but to downgrade you can remove the package via package manager `rm JuMP` and then re-install it at a specific version, for example `add JuMP@1.2.3`

The same problem with the new packages and even downgrading and reinstalling. Have you solved the problem?
