Clean installation does not create the attach.dylib file

[dr-costas]

Description

When doing a clean install of Vimspector with Vim 9.1 and with Plug, after doing VimspectorInstall debugpy or python install_gadgets.py --enable-python the file attach.dylib is not created.

Is it reproducible in vim?

Works with clean config?

Yes

Sample project works?

Reproducible with sample project

Minimal Reproduction

Do:

rm -rf ~/.vim/plugged/vimspector/gadgets/macos/debugpy
rm -rf ~/.vim/plugged/vimspector/gadgets/macos/download/debugpy

Run vim --clean -Nu .vim/plugged/vimspector/support/minimal_vimrc

Then inside Vim:

VimspectorInstall debugpy

Finally, check in:

ls ~/.vim/plugged/vimspector/gadgets/macOS/debugpy/build/lib/debugpy/_vendored/pydevd/pydevd_attach_to_process

but attach.dylib is not there.

Expected Behaviour

The attach.dylib should be created.

Actual Behaviour

The attach.dylib is not created.

Please state the actual problem and steps to reproduce it. The presence or absence of some DLL is not a functional problem.

[dr-costas]

The problem is that when I start debug, I get this:

0.48s - Expected: ~/.vim/plugged/vimspector/gadgets/macos/debugpy/build/lib/debugpy/_vendored/pydevd/pydevd_attach_to_process/attach.dylib to exist.

and then I get a huge red text error which goes away super fast

[dr-costas]

And basically the settings for Vim are:

{
  "configurations": {
    "Python: Attach To Vim": {
      "variables": {
        "port": "5678",
        "host": "localhost"
      },
      "adapter": "multi-session",
      "configuration": {
        "request": "attach"
      }
    },
    "Python: Run current script": {
      "adapter": "debugpy",
      "configuration": {
        "request": "launch",
        "program": "${file}",
        "args": [ "*${args:--update-gadget-config}" ],
        "justMyCode#json": "${justMyCode:true}"
      }
    }
  }
}

I would guess that the attach.dylib is needed here.
