I’m currently using Julia 1.8.2 on Windows 10 platform, and I wonder how to update Julia to 1.9.1 without re-install my packages, e.g., JuMP, etc. And I don’t like there are several Julia versions on my PC. So is there a simple implementation method?
juliaup option is a good long-term investment here (it saves time for future updates).
Otherwise, the traditional approach would be to repeat the steps that you took in the first place when installing the 1.8.x version (and delete the old version if you don’t need it anymore). I am assuming you opted for one of these (depending on your platform).
juliaup also lets you easily switch between versions (let’s say you want to test some preview version or use a different version temporarily).
