I am new to SageMath and am following the examples from the basic tutorials. The following command does not work:
plot3d(x^2 + y^2, (x,-2,2), (y,-2,2))
The error message is
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0:`sage-open/Users/xxx/.sage/temp/MacBook-Pro-(6)/1333/tmp_smrlkile.html 2>/dev/null 1>/dev/null &'
Is this due to the presence of parentheses in the auto-generated temporary directory? If so, how can I changed it?
