SageMath kernel folder not found while installing it to Jupyter environment

[Booodaness]

I was recently trying to install SageMath kernel into the global version of Jupyter using this command,

jupyter kernelspec install $SAGE_ROOT\local\share\jupyter\kernels\sagemath

Where $SAGE_ROOT is the default installation prefix of Sage. However, the above gave the error:

Traceback (most recent call last):

    with os.scandir(src) as itr:
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\\Program'

Jupyter and SageMath are installed properly on my system (Windows 10). Just in case this helps, the version of Sage installed on my system is 9.1. There were some plotting issues in more recent versions, so this was the best I could do for now, as an amateur.

How do I fix this error?

Someone has tried to do this before but it wasn't simple, because it does not recognized Windows style paths. I wrote about it here some time ago but I don't recall if the solution works: https://stackoverflow.com/questions/51300460/how-to-install-sagemath-kernel-in-anaconda/51308972#51308972

Thanks a lot!! That looks really helpful!!

@embray Couldn't resolve the issue in the way you described :( but still thanks, it helped me understand the issue even as a very new programmer.

Btw, can we install the SageMath kernel to Jupyter from the Sage command line? Using SageKernelSpec (http://www2.math.ritsumei.ac.jp/doc/static/reference/repl/sage/repl/ipython_kernel/install.html)? I didn't understand which command can do that, in the documentation.

@Booodaness By the way, that's some unofficial mirror of the sage docs for a fairly old version; The up-to-date version is here: https://doc.sagemath.org/html/en/reference/repl/sage/repl/ipython_kernel/install.html

However, I don't think anything on there is going to help you.

It's been long enough since I last looked at this issue that I don't recall what all the problems are. One of the biggest problems was simply the path issue, which will need to be fixed, I think in Sage. The other is the poller issue. I think this will require some fixes before it can really work easily (which I would indeed like it to). Then I can add instructions or even a command to make this simpler to do.

@embray Thank you for sending the updated version!

Thank you.

Please keep this issue open. I think it's worth having a clean resolution (which may require some upstream fixes to Sage and/or Jupyter)
