I installed Sage and JupyterLab in WSL (Arch Linux).

sudo pacman -S sagemath
sudo pacman -S jupyterlab

Its command line seems to work fine. image description

However, after the first run of sage -n jupyterlab that successfully opens JupyterLab, I cannot open JupyterLab again after restarting my computer.

Even if I copied those URL-like links it mentioned.

How should I adjust it correctly?

This might point to a "too cautions" firewall configuratin : your machine refuses connections from itself (localhost, a. k. a. on the port 8927. traceroute and nc are your friends...

WSL configuratuion may also be in cause : it might or might not accept connections (and ISTR that it may depend on the WSL version...).

BTW : textual cut'n'paste is way prefferable to screen dumps...

@Emmanuel Charpentier Thanks. I'm not sure if it's because of the directory, but I encounter an error when opening WSL from the directory in Windows. However, when I switch back to the WSL directory, it opens correctly. The directory may have a significant impact.

Instead of sage -n jupyterlab, try running jupyter lab.

The error might have to do with the "redirect file". See
