I’m trying to install a number of packages ( [Denice\_van\_Herwerden / jhrmstoolbox.jl — Bitbucket](https://bitbucket.org/Denice_van_Herwerden/jhrmstoolbox.jl/src/main/)) but I get
ERROR: Method overwriting is not permitted during Module precompilation. Use ` __precompile__ (false)` to opt-out of precompilation.
I have seen questions to handle this in their own code, but I’m trying to install a package from someone else. I use Julia 1.10.0 because that is the version the bitbucket page says it was last updated to. Thanks.

I would recommend using the latest 1.10 patch release. Patch releases exist to fix bugs.
