Stop creating new threads for the same issue. This is annoying.
And again: stop posting screenshots..use proper copy & paste of error message - as advised multiple times.
Apparently, "relstorage" is using the (relatively) new
"wheel distribution format" and your "buildout/setuptools" installation
does not yet fully support this format.
I do not know the solution. Upgrading "buildout/setuptools" might
work (but I am not sure).
