installing the extension in a default jupyter/scipy-notebook container does not work

[oroszl]

I was trying to install this extension in a docker container created from the official jupyter/scipy-notebook image that is hosted on docker hub. Apparently this image has jupyterlab version 0.30.6 installed. I followed the install descriptions as a local user by doing pip install . --user and jupyter labextension install . which ends with the following warnings

warning " > pdfjs-dist@2.0.230" has unmet peer dependency "webpack@^2.0.0 || ^3.0.0".
warning "pdfjs-dist > worker-loader@1.1.0" has unmet peer dependency "webpack@^2.0.0 || ^3.0.0".

"/home/jovyan/jupyterlab-latex" is not a valid extension:

after this doing jupyter serverextension enable jupyterlab_latex runs without warnings and produces the following normal looking output:

      jupyterlab_latex  OK

launching jupyterlab and right clicking on a .tex file the menu does not have the expected Show LaTeX Preview option.

are there some unmentioned dependencies that I am missing ?

I'm experiencing this same issue, but I'm trying to install this in my base anaconda installation also with jupyterlab 30.6.

[mpacer]

We haven't officially released a version with known compatibilities.

The plan is to release it next week where it will be compatible with jupyterlab version 0.31.

Hi @oroszl and @t-makaro , we have now released the first functional version of this extension, as well as updated the build instructions. If you have any problems, feel free to reopen this or open a new issue.

[oroszl]

@ian-r-rose is the new version on pip already? I tried to simply follow the non development installations and it goes through without any problem but I still do not have any Show LaTeX Preview in my right click menu.

[ian-r-rose]

It should be: https://pypi.python.org/pypi/jupyterlab-latex Have you installed the labextension as well?

[t-makaro]

Similar problem. I installed from pip, and ran the labextension install and serverextension enable, and it appeared to work fine, but Show LaTeX Preview is not available.

[ian-r-rose]

What version of JupyterLab do you have installed? Are there any error messages displayed during the build?

Can you show the result of jupyter labextension list?

[oroszl]

i did the following pip install jupyterlab_latex --upgrade --user jupyter labextension install @jupyterlab/latex I have the following versions:

jupyterlab (0.31.1)
jupyterlab-latex (0.1.0)

[t-makaro]

I got these warnings during labextension install

@t-makaro It seems that the README.md is not completely clear about where to click. Can you verify that you are right-clicking in a .tex document?

[t-makaro]

Ok, I thought it was on the file browser. I see the command, and now I get the LaTeX Error:

@oroszl Can you show the result of jupyter serverextension list?

You may need to enable it by running

jupyter serverextension enable --sys-prefix jupyterlab_latex

[oroszl]

That seems to solve the issue! I have notebook version 5.3.1 though.. so it seemed from the instruction that this line is not needed anymore.

[ian-r-rose]

Yes, the intention was that after notebook 5.3 it should no longer be necessary to do the serverextension enable step. This feature is brand new, though, and it seems that something has not gone according to plan. I will look into it further...

[mpacer]

I think if you run into this and run pip install -U jupyterlab-latex that should also run the serverextension enabling step even if you already had a version of this. There is still an issue where this doesn't work in an editable install, but that's technically a different issue, so I'm going to close this issue for now.
