I installed the software by macos`s SageMath-10.5_x86_64.dmg
<https://github.com/3-manifolds/Sage_macOS/releases/download/v2.5.0/SageMath-10.5_x86_64.dmg>
file.It can run simple code,such as 1 +1 etc.
But when I run some advanced pkgs, it will throw some errors, for example:
when i run this code:
R.<v> = 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 Traceback (most recent call last) Cell In [1], line 2 1 R =
LaurentPolynomialRing(ZZ, 'v', names=('v',)); (v,) = R._first_ngens(1) ---->
2 W = CoxeterGroup('A3', implementation='coxeter3') 3 H =
IwahoriHeckeAlgebra(W,
v**Integer(2)); Cp=H.Cp() 4 Cp.product_on_basis(W([Integer(1),Integer(2
),Integer(1)]), W([Integer(3),Integer(1)])) File

I try to install this pkg by pip install coxeter3 or sage -i <options>
<package name> ,
all ways were failed. How to install sage with package coxeter3?
Looking forward to your reply.
