How to install jupyter using deno v1.41.x

According to the documentation https://docs.deno.com/runtime/manual/tools/jupyter the command should be deno jupyter --unstable --instal. This leads to an error because --unstable no longer exists. But apparently there is also no flag named --unstable-jupyter? Is this a bug?

Does running it without any unstable commands work? We might have forgotten to update the documentation

My mistake. The "--unstable" flag is not necessary. If you execute the command without "--unstable", you get the following warning:

Warning "deno jupyter" is unstable and might change in the future.

If you execute the command with "--unstable", you will receive the following warning:

⚠️ The `--unstable` flag is deprecated and will be removed in Deno 2.0. Use granular `--unstable-*` flags instead.

But my mistake was that I forgot to install JupyterLab. In the end everything seems to be correct.

I have the same error. The jupyter lab works. The deno jupyter kernel is not installed.
