Installing Alembic 1.6.5: Resolving 'greenlet' Build Error

The error message suggests that the installation of the package 'greenlet' failed while trying to build a wheel for it. The specific error seems to indicate a missing file ('basetsd.h') required by the Microsoft Visual C++ compiler.

One possible solution is to install the Microsoft Visual C++ Build Tools, which should include the missing file. Another solution could be to try installing an older version of 'greenlet' that may not require this file.

It's also worth noting that the Python version being used is 3.11, which is currently in beta and may not be fully supported by all packages. Trying the installation on a stable version of Python (such as 3.10) could also be worth attempting.
