> Last night, I was trying to get a Lux tutorial running. This was the order in the tutorial: using Lux, ComponentArrays, SciMLSensitivity, LuxAMDGPU, LuxCUDA, Optimisers, OrdinaryDiffEq, Random, Statistics, Zygote, OneHotArrays, InteractiveUtils Some I had. Others needed to be installed, which seemed to have worked fine. However, when trying to use the packages, I kept getting a message to restart Julia because one of the packages was not precompiled correctly (ComponentArrays, or some Compone…

Basically, I got it working by removing the packages from all my projects. Then doing this:

> But it appears using a temp directory was insufficient to isolate the problem. What I did is remove all those packages from my project then run `]gc --all`. I saw this did delete them in `~/.julia/packages`.

Then reinstalled the packages one by one. The order maybe matters but if you see an error then remove the last one, do the garbage collection, then try with another.

I think in the end just installing one by one after making sure the packages were actually deleted worked (by the package manager, doing it manually sounded like a bad idea).

**Edit:**  
People who know better than I thought it was an issue with how the package manager deals with the new extension packages introduced in version 1.9. So I assume this issue is being worked on, but for now that worked for me…
