Both julia and juliaup are in my path, but still juliapkg downloads a new version of julia

I need julia version 1.5, but even though julia and juliaup are in my path juliapkg installs a new version. What am I missing here? Thanks in advance.

Hi, sorry for the slow reply but from your other issue it looks like you've figured this out now so closing.

Hi no problem, thanks for replying. I'm not sure if this issue is fixed though. From the documentation I had the impression that any Julia installation that is in the PATH will be selected, without first checking juliapkg.json. This is still not happening in my case. But if juliapkg.json is always checked and the version specified there is looked for in the PATH, then it did work and this issue can indeed be closed.

JuliaPkg always checks juliapkg.json and will refuse to use an incompatible version of Julia. Hence the readme says "If julia is in your PATH, and is compatible, that is used."

Got it, thanks!

In my case I had no juliapkg.json, I had julia 1.9 on my PATH, and it still tried to upgrade. I can understand this behaviour, but I think it should be documented. thanks
