Registering GAP with Jupyter

[Yue-Zhengyuan]

In the README file, it is said that the GAP Jupyter kernel must be registered by running the following command in the pkg/JupyterKernel directory of your GAP installation:

pip3 install .

On macOS Monterey (12.1, Intel), I installed Python with Anaconda, and GAP with Homebrew. When I try to run the above command, I get the following error:

ERROR: Command errored out with exit status 2:

But then I tried directly running python setup.py install (here python is my anaconda-installed Python) and it works. Maybe the documentation should be updated?

Thanks @Yue-Zhengyuan - the README you see on GitHub refers to the new version of the package, not yet included in the GAP release. The one you get with Homebrew is the latest release of GAP 4.11.1 and packages at that time. You had to check the README from your local installation of the JupyterKernel package, and it indeed should say python setup.py install. Glad that it worked that way.
