Description of Issue
Tried to install textual on an Ubuntu 22.04 system with ROS 2 Humble installed. Had a bunch of conflicts during installation and the installation failed.

Install command: python3 -m pip install textual. Also tried python3 -m pip install textual-dev with the same results.

Output (See last line and the line before):

Defaulting to user installation because normal site-packages is not writeable

A possible replacement is to upgrade to a newer version of devscripts or contact the author to suggest that they release a version with a conforming version number.

For those not familiar with your environment, do you think you could document what a "ROS 2 Humble" is and why it might be relevant here?

with ROS 2 Humble installed. Had a bunch of conflicts during installation and the installation failed.

Presumably whatever Python packages involved with ROS 2 Humble conflicts with some Textual dependencies? Have you tried installing Textual in a virtual environment?
