Can you share the output of:
```julia-auto
using Pkg
Pkg.status()
```
?
And the output of
```julia-auto
versioninfo()
```
?

Now I might have figured out what the problem is. It could be because I used a portable version of Julia 1.10. When I used another installation version of 1.11, everything worked fine.

You deleted the LD\_LIBRARY\_PATH in your reply, but it could also be the reason for your failure. You could try to set it to an empty string.

Ah, I think it’s too lengthy. What is this for? I see that it involves many paths. If it is set to be empty, will it cause any bad consequences?

When loading shared libraries, the OS looks in the folders in this path first. The libraries Julia needs are, for example, in this directory:
```julia-auto
/.julia/juliaup/julia-1.10.10+0.x64.linux.gnu/lib/julia
```
If the same libraries are - in a slightly different version - in any of the folders in
LD\_LIBRARY\_PATH, those are loaded instead of the official Julia libraries. This usually results in a crash.
This variable may be required for other command-line applications you are using. If so, you should set it only for these applications and delete it before starting Julia.

It makes sense. Thank you very much.
But I checked the paths in `LD_LIBRARY_PATH` carefully and didn’t find any julia related path.

Not only Julia related paths can cause problems, but any folder that contains any of these libraries:

It seems you are right, @ufechner7 . Thank you very much! 🤝
But, after I typed `ENV["LD_LIBRARY_PATH"]=""`, I `add CUDA` and `using CUDA` again, and the same error also occurred.
And, do I have to execute `ENV["LD_LIBRARY_PATH"]=""` every time I restart Julia?

I would add
```julia-auto
export LD_LIBRARY_PATH=""
```
to `.bashrc` if you have this file in your home folder. This might break other tools you use, though. Or you add
```julia-auto
alias jl='export LD_LIBRARY_PATH=""; julia'
```
to `.bashrc` and launch Julia by typing `jl`.
I think that setting this variable within Julia is too late and has no effect.

Given various issues, I have decided to abandon using a portable version of Julia while an installation version of Juliaup is in existence. I found that if there are two Julia versions with the same version number, even if one is installed via Juliaup and the other is a binary file, the latter’s packages cannot be installed and used properly.

I would not use a portable version with CUDA, because CUDA is specific to a graphics card, which is usually different for each computer.
Can you mark one of the answers as a resolution of the initial question?
