Program Terminating

 

The specific combination of Greenlet version resolved (v2.0.2), OS platform (macosx_10_*_x86, wheels are apparently release-specific on Mac) and Python version (CPython 3.10) has not been published as a pre-compiled "wheel package", so pip is trying to compile it, but the Python installation that FME ships with is not configured for compilation. You could always install it in a separate Python 3.10 environment and copy it over to the FME Python plugins location manually.

 

EDIT: You can also run pip install --prefer-binary sqlalchemy, which causes pip to "Prefer older binary packages over newer source packages." when doing dependency resolution.
