Sage Installation Issues on mac

[Masoud Soroush]

Hello Sage Team,

I am contacting you to ask for help in regard to Sage installation on my macBook pro. I would like to install Sage on my macOS Big Sur (version 11.1) with Intel Core i7. Among the options for installation, I chose SageMath-9.2.app.dmg (I tried the other 2 other options, but I ran into even more severe issues). After dragging SageMath into the Applications folder, a shortcut is created. When I execute SageMath through the created shortcut, a Safari browser is opened for the Jupyter notebook asking to wait until Jupyter initiates. But shortly after, I get a message that Sage cannot start, and I am referred to the log file which has been copy pasted in below:

***************************************************************************************************

Traceback (most recent call last):
  File "/Applications/SageMath-9.2.app/Contents/Resources/sage/local/lib/python3.8/site-packages/sage/repl/ipython_kernel/install.py", line 307, in have_prerequisites from notebook.notebookapp import NotebookApp

┌────────────────────────────────────────────────────────────────────┐

Please wait while the Sage Jupyter Notebook server starts...

The Jupyter notebook requires ssl, even if you do not use
https. Install the openssl development packages in your system and
then rebuild Python (sage -f python3).

**********************************************************************************************

I have installed "openssl" package through anaconda, but it still seems to be an issue here. If I just go ahead and run "./sage -f python3" (as the above log file suggests at the end), after a long compilation, I get an Error 1 message (please see the attached file). Now not only do I get the Jupyter issue resolved, I will also lose the ability to run Sage through Terminal! Could you kindly look into this issue and instruct how to proceed? I really hope for jupyter notebook integrated solution, as programming in terminal is not convenient.

Thank you for your assistance,
Masoud

Hello Nathan,

Thank you so much for your tip! It indeed solved the problem, and I can now run Sage commands in Jupyter environment! Thank you again.

Best,
