Dictionaries not found

[tibcal]

Hello, First of all, thank you for this project. I've install spellchecker, with no errors. But when launching jupyter lab, dictionaries are not found, although the repertory "dictionaries" is create in the right place during installation.

Output of the terminal : [W 2021-07-09 15:02:51.717 ServerApp] 404 GET /spellchecker/language_manager?1625835770998 (127.0.0.1) 542.53ms referer=http://localhost:8888/lab

System : Fedora

It looks like the server extension is not enabled/installed properly. Could you provide the output of the following commands, please:

jupyter serverextension list

and:

# note the extra space
jupyter server extension list

and

jupyter lab --version

and

pip list | grep jupyter-server

[tibcal]

No output for jupyter serverextension list Output of jupyter server extension list :

Config dir: /home/thibaut/.jupyter

Config dir: /usr/local/etc/jupyter

Output of jupyter lab --version : 3.0.5

Output of 'pip list | grep jupyter-server' :jupyter-server 1.2.2

How did you install the spellchecker extension? Conda, pip, extension manager?

[tibcal]

First of all via the extension manager (web interface), but I've got errors when building jupyter lab after installation. Then I tried and managed to install via pip.

[krassowski]

Could you please try running:

jupyter serverextension enable jupyterlab_spellchecker

and let me know what is the output (and if it ends with "OK", if it the spellchecker is now working after restarting JupyterLab).

Also, I would recommend upgrading JupterLab (current is 3.0.16), upgrading jupyter-server (current is 1.9.0).

[tibcal]

I've upgraded jupyterlab and jupyter-server, and try jupyter serverextension enable jupyterlab_spellchecker. Output is OK, but spellchecker is still not working.

[krassowski]

What is the output of

jupyter serverextension list

this time?

[krassowski]

Maybe there is something relevant in logs when starting with jupterlab --debug?

[tibcal]

config dir: /home/thibaut/.jupyter

With debug, nothing more about spellshecker than : [W 2021-07-09 16:33:08.313 ServerApp] 404 GET /spellchecker/language_manager?1625841188122 (127.0.0.1) 17.71ms referer=http://localhost:8888/lab

[krassowski]

Well there should be:

[I 2021-07-09 15:46:07.746 ServerApp] jupyterlab_spellchecker | extension was successfully linked.

at the very top. I am running out of ideas, sorry :(

Are you maybe starting jupyterlab as a root (with sudo?). Do you have any extra configuration options enabled?

[tibcal]

I've uninstalled then reinstalled jupyter lab, and it's finally working ! Thanks for your help.

[krassowski]

That's great, I'm glad it is working now! I will close this issue, but if you encounter this problem again and get to narrowing down the cause please feel free to share it here.

Hello, Michał,

I have exactly the same problem as tibcal.

Spellchecker does not work, output in the terminal:

Maybe there is some conflict with different versions of jupyter components?
Is there a way to debug the spellchecker extension?

I use Gentoo.

It seems that jupyterlab_spellchecker extension is not loading properly during jupyterlab startup. When I interrupt jupyterlab by Ctrl+C, it outputs "Shutting down 1 extension" (this extension is jupyterlab; at startup, log output contains "JupyterLab extension loaded from /home/saha/.local/lib/python3.9/site-packages/jupyterlab")

[krassowski]

Hi @smirnovskysaha,

your jupyter server extension list result is empty - it means that the extension is not enabled for JupyterLab 3 (see this explanation).

Please run the following command:

jupyter server extension enable jupyterlab_spellchecker

and again run:

jupyter server extension list

Please let me know what is the output and if the spellchecker starts working for you after that.

[smirnovskysaha]

@krassowski, thank you very much!

In my case the proper command to enable the extension was

jupyter server extension enable --user jupyterlab_spellchecker

till I do not use system-wide installation of JupyterLab.

Now the extension works great!

[krassowski]

That's great to hear, thank you for getting back to us and leaving this hint!

We generally recommend using virtual environments where adding --user is not needed, but indeed once you start using --user you need to be careful to always remember to add it.
