Pretty simple problem. I can provide whatever other information you may need on request.
The ipython documentation claims that Cygwin is supported.
I'm running Cygwin 3.6.9 on Windows 11 Professional with Python 3.12.12 and Pip 26.0.1. I'm installing it from within an active virtualenv created with python -m venv.
pip install ipython, which works on all other platforms, fails on Cygwin with the following error output:
$ pip install ipython
...

note: This error originates from a subprocess, and is likely not a problem with pip.

I was able to successfully get it to install without error using pip install colorama decorator ipython-pygments-lexer jedi matplotlib-inline pexpect pygments stack_data traitlets followed by pip install --no-deps ipython. It appears to work fine so far (I have not exercised all of the capabilities yet).
Note that, despite my having installed this in a virtualenv, I get the following startup warning from ipython:
$ ipython
