# How do I install Jupyterlab ?

I am on Windows 10, 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 ?

from SAGE_ROOT, can you call

`./sage -i jupyterlab`
