Re: [sage-support] completely uninstalling SageMath

Thanks Marc! Following your advice I went to System Settings > Privacy & Security -> Automation and found that SageMath had been denied control over System Events (by me, I assume). Allowing SageMath control over System Events permitted SageMath to use Terminal.app and solved my problem! I must

[sage-support] macos install sagemath but can not install coceter3

when i run this code: R. = LaurentPolynomialRing(ZZ, 'v') W = CoxeterGroup('A3', implementation='coxeter3') H = IwahoriHeckeAlgebra(W, v**2); Cp=H.Cp() Cp.product_on_basis(W([1,2,1]), W([3,1])) Cp.product_on_basis(W([1,2,1]), W([3,1,2])) it will be wrong and the error msg is : RuntimeError Trace
