Issues with Flet in Arch Linux

[G-Pereira]

Hey! I am trying to create a package definition for kintree in Arch Linux but although I am able to build it and install it I cannot run it Error I get while running:

Traceback (most recent call last):
  File "/usr/bin/kintree", line 5, in <module>
    from kintree.kintree_gui import main

ImportError: cannot import name 'FLET_APP' from 'flet_core.types' (/home/gpereira/.local/lib/python3.11/site-packages/flet_core/types.py)

build() {
    cd "$srcdir/$_name-$pkgver"
    python -m build --wheel --no-isolation
}

package() {
    cd "$srcdir/$_name-$pkgver"
    python -m installer --destdir="$pkgdir" dist/*.whl
}

any idea what I might be doing wrong?

@G-Pereira you have the wrong version of Flet installed to run Ki-nTree. There were some changes between the latest pip version and the one used here which break Ki-nTree and for now nobody had time to fix them. If you use Flet for some other packages as well I would recommend you to setup a virtual environment for Ki-nTree and install it there, then the requirements should be correct.

Thank you @T0jan for the quick response !

My goal is to allow one to install the package and decide if it is ok to downgrade the flet version on his system or not.

Personally I am fine with it since I don't use Flet for anything else.

I already did the changes to require Flet 0.7.4. I will test and close this if everything is ok.

Got it fixed. kintree is now available in Arch Linux!
