RPA.Assistant: Cannot install rpaframework-assistant because flet 0.4.2 (and 0.2.2) does not exist

[LydiaPeabody]

It looks like flet v0.4.2 and earlier have been removed from pypi: flet release history

This blocks installing RPA.Assistant.

Observed this in a python 3.8.13 project running in Linux using poetry for dependency management, with error message: Because rpaframework-assistant (2.2.1) depends on flet (0.4.2) which doesn't match any versions, rpaframework-assistant is forbidden.

Minimal reproducible steps run in using python 3.10.12 on Windows:

python -m venv .venv
.\.venv\Scripts\activate
pip install rpaframework-assistant 

Produces error output:

To fix this you could try to:
1. loosen the range of package versions you've specified                               
2. remove package versions to allow pip attempt to solve the dependency conflict

Thank you for the issue report. We have received a similar report in our Developer Slack and are working on a fix as soon as possible.

This problem was caused by flet package maintainers removing released versions from the PyPI so we are in process of making our own forked PyPI package.

Thanks for the quick fix @mikahanninen and @bogdancondurache!

Do you know the reason of this sudden Flet Pypi package removal?

[bogdancondurache]

@apallier Apparently that's a common thing they are doing, mostly only keeping the last few releases.
