standalone mode failed

Python 3.10.2
pip 22.0.2

I've installed all this:

`https://raw.githubusercontent.com/chubin/cheat.sh/46d1a5f73c6b88da15d809154245dbf234e9479e/requirements.txt`
This is the error with mode=auto

```

```

Start with lib/standalone.py and follow its imports through lib/adapter/question.py, then inspect the pinned requirements.txt and reproduce mode=auto in the reported Python environment. Done means standalone mode starts without the reported ICU import error and its behavior is covered by an appropriate test or documented reproduction.
