Deap is using Python2 syntax here so Python 3.10 doesn't support it and so there is a syntax error. Before setuptool 58, it uses a builtin tool called 2to3 to automatically convert such Python 2 syntax to corresponding Python 3 one but 2to3 tool is just a temporary solution that helps Python 2 to Python 3 transition more smoothly and since Python 2 is already EOL the 2to3 tool is also dropped since setuptool 58. Without conversion Python 3.10 won't load Python 2 code. Deap developers are aware of the issue and solving it (see this issue). For now, you can downgrade setuptool version to 57 using pip install --upgrade setuptools==57.5 and wait deap to fix the issue.
