That does not explain why you have the error, given that Sage has an older version of tornado and SageMathCell is supposed to use whatever is installed in Sage. sockjs.tornado does not seem to be maintained much - I managed to get a CORS-related patch in, but the version on PyPi still does not have it. Perhaps nowadays sockjs is just not really necessary anymore? -- You received this message because you are subscribed to the Google Groups "sage-cell" group.
