Cannot Open Notebook

[gh-robotdna]

Installed Sage through: ​https://anaconda.org/conda-forge/sage

with Anaconda.

In terminal, typed "sage" which functioned as expected and then "notebook()" which then proceeded to fail and throw an error:

sage: notebook()

Should I just be using "sage --notebook=jupyter" instead? If so, please remove "ype "notebook()" for the browser-based notebook interface." in the startup message as it fails and it is misleading.
