jupyter labextension list

JupyterLab v2.1.5
No installed extensions

Did the error mean that JupyterLab v2.1.5 is not supported yet? Can it be fixed? Thank you.

(Besides, WebIO.install_jupyter_nbextension() also failed but with a different error.)

I have the same problem with the current jupyterlab 2.2.2 from the package repo in Arch

[Teo-ShaoWei]

I am met with the same issue... I managed to find the symptomatic cause in the following file:

WebIO.jl/packages/jupyter-lab-provider/package.json

Lines 10 to 15 in 276911f

	"@jupyterlab/application": "^1.0.1",
	"@jupyterlab/docmanager": "^1.0.1",
	"@jupyterlab/docregistry": "^1.0.1",
	"@jupyterlab/notebook": "^1.0.1",
	"@jupyterlab/rendermime": "^1.0.1",
	"@jupyterlab/services": "^4.0.1",

Which meant that Jupyterlab v1 is supported (and Jupyter services v4). However, Jupyterlab has since made a major version up to v2 (and Jupyter services to v5). To support that, we might need to use something like ^1.0.1 - 2 to meant that support will continue for the rest of v2.

However, there is a reason why sem ver is written the way it is. Every major version up might have interface changes that will break external compatibility. We would need to rely on someone who can test this authoritatively to make sure nothing breaks between WebIO and Jupyterlab v2 first before a PR to change those values.

I have the same problem with the current jupyterlab 2.1.0

[jlumpe]

Issue on jupyterlab 2.x compatibility: #397. Currently, it seems like the workaround is still to downgrade to 1.x.

[jarbus]

Still have this issue on 2.2.9

[jlumpe]

@jarbus which version of WebIO are you using? 0.8.15 should support jupyterlab v2.x but I am having issues getting it to work myself.

[jarbus]

@jlumpe v0.8.15

[jlumpe]

@jarbus Nevermind, the issues I was having ended up just being bugs in IJulia's display system. I am able to get it to work with WebIO 0.8.15 and jupyterlab 2.2.6. Were you having errors in the extension installation process?

[jarbus]

Interesting, just tried again and got no errors. Thanks!
