Arch Linux User Repository

Unfortunately, the latest sympy is 1.10.1, which still triggers the error:

pkg_resources.DistributionNotFound: The 'sympy<=1.10,>=1.8' distribution was not found and is required by Mathics3

Updated for sympy 1.10, the incompatibility error should be solved again.

I get a similar error as archisman when running mathics for sympy 1.10

I confirm that now it works with sympy 1.9

Updated for sympy 1.9, the incompatibility error should be solved.

I get the following error due to incompatibility with sympy version.

Fixed for sympy 1.8. Thanks a.kudelin.

Not working with sympy 1.8, applying this PR as a patch will help probably: https://github.com/mathics/Mathics/pull/1365

In preparation for the 2.0.0 release, some parts of Mathics have been split off and moved to separately installable packages. In particular:

• The Django front-end is now on mathics-django

• Scanner routines and character translations are now on mathics-scanner

More info in the release notes.

Thank you for so quick fix! Server now starts correctly and I don't have any issues. Assuming sympy follows semantic versioning, there are no breaking changes and no room for worries.
