I have just installed Sage 8.1 on MacOS Sierra. After I launch the application, I am told Jupyter did not start and I get offered to open the log. Doing so, here is what I get there
/Applications/SageMath-8.1.app/Contents/Resources/sage/src/bin/sage-env: line 322: [: /Applications/SageMath-8.1: binary operator expected
Traceback (most recent call last):
File "/Applications/SageMath-8.1.app/Contents/Resources/sage/src/bin/sage-notebook", line 13, in <module>
from sage.env import SAGE_ROOT
ImportError: No module named sage.env
