My understanding is that, to install jupyterlab I have to run:
(1) sage -pip install jupyterlab (2) sage -i jupyterlab_widgets
is this right ?
but I get the following error when I execute them:
'sage' is not recognized as an internal or external command, operable program or batch file.
.....
Is there an alternative way to install jupyterlab without messing around with environment variables ?
