This error occurs when I’m trying to use Debugger.jl, what does it suggest?

PatrickHaecker · May 7, 2025, 5:22am

I can’t reproduce your error with Julia 1.11.5. Can you please upgrade to 1.11.5 and try again?
What is your Debugger version? Mine is:

(@v1.11) pkg> status Debugger
Status `~/.julia/environments/v1.11/Project.toml`
  [31a5f54b] Debugger v0.7.11

WalterMadelim · May 7, 2025, 5:54am

I’ve upgraded. But the issue persists.

Here is a related open issue. I have no idea what to do. (I remember that I could use this package properly around 2 years ago.)

Can you reproduce the error with julia --startup-file=no?

WalterMadelim · May 7, 2025, 6:41am

Yes, it persists.

PatrickHaecker · May 7, 2025, 7:03am

Just to be sure: That’s happening in a newly opened REPL without executing anything else before, correctly? And you are in a REPL outside of e.g. VS Code?

Which OS are you using? This is Windows, isn’t it?

Your environment looks strange (uc24). Can you try it in the default environment? How does your environment uc24 look like?

WalterMadelim · May 7, 2025, 7:17am

Yes.

I do it in PowerShell, which I open inside VScode.
I use the portable version for win11.

I guess it’s nothing wrong with VScode. Because I’ve used this package 2 years ago (with the same setting). At that time I can use this package properly (e.g. step into a function, executing a line etc.)

It is merely a folder in windows.

WalterMadelim · May 8, 2025, 1:09am

windows cmd

windows powershell

Therefore I guess it’s not owing to VScode.
@kristoffer.carlsson Could you please take a look? Thanks.

PS is there anyone know how to paste code in cmd and powershell (win11)? I tried ctrl+v, ctrl+shift+v, or right click, they almost don’t work! I don’t know why are they so difficult for users.

PatrickHaecker · May 8, 2025, 6:18am

Thanks for al the tests. I asked about VS Code, because it has its own Debugger integration so it’s good that we could rule this out.

I am really at a loss here. Do you have the possibility to try the non-portable version and install it via juliaup?

WalterMadelim · May 8, 2025, 6:20am

Yes I can have a try. (I haven’t try this ever before. Because the portable version can be put in a non-system disk.) I’ll update later.

WalterMadelim · May 8, 2025, 6:44am

I’ve followed the recommended way (i.e. juliaup) and re-installed. But the issue persists.
The following are not the previous portable version, since I had deleted it in the PATH of ENV variables.

Thanks for the additional test. Again no luck. :-/

You still seem to use the uc24 environment, however. Could you open your package manager and just enter activate or start it in a different directory? If it still shows uc24 it’s probably still the portable version and the path is still somewhere (maybe only in RAM and a restart could change it).
If you open a command line and start the julia command from juliaup with its full path, you could also override path variables.

WalterMadelim · May 8, 2025, 6:59am

Is my operation correct?

PatrickHaecker · May 8, 2025, 11:09am

Yes, thanks, we now know that it affects both portable and non-portable Julia and both your custom and the default environment. Unfortunately, I don’t have further ideas. I think we are at the point where you should report an issue in the Debugger.jl package.

I hope someone more knowledgeable than me can jump in and help you out. If not, the next step I would think of were to debug the Debugger package. I am fully aware of the irony. You could either try Rebugger or you could add some print statements. The call stack of your error is not that deep, so there is a chance to find something useful quite soon, but I am not sure whether you want to go down this rabbit hole.

WalterMadelim · May 8, 2025, 12:48pm

Thanks you. There is already a (spot on) open issue there.
Maybe there are some updates that violate things, not sure whether it comes from win11, or julia packages.
I’m not an expert at computer programming. The ironic fact might be that I could use this package properly 2 years ago. I don’t use it continuously because I find that for the most of the time it suffices to use @info etc. to debug. However, for those code that are not written by me and involve a deep hierarchy of calls, I do need a tool like Debugger.jl.
