Can't load LaTeX Workshop extension

[maresb]

I am trying to run the LaTeX Workshop extension (james-yu.latex-workshop). I have tried with extension versions 8.7.2, 8.10.0 and 8.11.0, all with the same results. I get the error command 'latex-workshop.view' not found when I click the "View LaTeX PDF File" icon, and nothing else happens.

Digging deeper, enabling source map support, the Output termninal "Log (Remote Extension Host)" shows the following error message.

[2020-06-24 00:09:19.066] [exthost] [error] Activating extension James-Yu.latex-workshop failed due to an error:
[2020-06-24 00:09:19.067] [exthost] [error] Error: Cannot find module '/home/jovyan/.local/share/code-server/extensions/james-yu.latex-workshop-8.10.0/out/src/main.js'

The out/ subdirectory does not exist.

My interpretation is that out/ is supposed to contain build targets which are somehow not being built. Indeed, the extension's GitHub contains /src/main.ts but no /out/. I don't know any TypeScript, so does this make sense? Any idea how to fix it?

• Web Browser: Firefox
• Local OS: Ubuntu 20.04
• Remote OS: locally-running jupyter/tensorflow-notebook Docker container
• Remote Architecture: x86_64
• code-server --version: 3.4.1 48f7c27

Note: I am able to manually install the .vsix.

Temporary fix: extract /extension/out/ inside VSIX, as it contains a valid out/ directory.

@nao20010128nao, sorry I don't understand. Where is /extension/out/ and what would be the full command? (Note: I was able to install from VSIX.)

[Lesmiscore]

@maresb Because VSIX file is actually ZIP file, you can extract it using ZIP utilities like unzip command.

I had the same problem when trying to build LaTeX-Workshop myself for the first time (in local VS Code):

npm install vsce
git checkout https://github.com/James-Yu/LaTeX-Workshop
cd LaTeX-Workshop
vsce package
code --install-extension latex-workshop-*.vsix

While it installed successfully, it did not load. What I was missing, after the git checkout, was to open LaTeX-Workshop in VS Code, F1, ">Run Build Task". Did that, repackaged and installed, and got it working.

Hope this helps anyone.

The extension now installs and provides syntax highlighting but none of the other functionality works. Tested with code-server v3.8.0 in both Firefox and a Chromium-based browser.

I installed via vsix in coder-server 3.9.0
The pdf view doesn't work like explained in other issues.
Building does Work

And highlighting doesn't work anyone a clue how to fix it or why it might not hightlight anything?

edit: sorry got it working Latex workshop doesn't support visual studio Dark or light color theme. Dark + works fine :)

For those facing the same issue

run

curl -fsSL https://gist.githubusercontent.com/HannesGitH/bf70790accef0773821fd6b83b335292/raw/latex-workshop_code-server__quickfix.sh | sh 

on your remote host for a quick fix

(see gist)

edit: this fix builds upon @nao20010128nao solution:

Temporary fix: extract /extension/out/ inside VSIX, as it contains a valid out/ directory.

edit2: you might need to change some stuff in the script if you're not on Debian or having a non-standart install

edit3: you need to reload your vscode instance e.g. just reopen the same folder

@HannesGitH your scripts loads out from the v3.9.0 asset into an v8.15.0 install. Is that intended?

[HannesGitH]

@bersbersbers it wasn't, thanks for pointing it out 👍 _{(it was late and i accidentaly put the version of code-server there :D , it worked though )}

fixed it , the fetched versions are now the currently installed ones

[HannesGitH]

ok sadly it seems like my workaround script wont work with 8.18. onward.. (at least in my setup afaik)
havent looked into why yet, just reverted to an older version

I can confirm this issue still exists on code-server 3.12.

Just to report: LaTeX Workshop v8.23.0 works fine under code-server 4.0.1.

Both code-server and texlive are installed over homebrew on MacOS 12.1.

Note that the pdf previewer is running on a separate port than code-server, so in order to make it work remotely (e.g., from docker or ssh), one has to forward this port as well. See James-Yu/LaTeX-Workshop#2206. However, it is possible to use another previewer: just search for "pdf" in extensions. "Papyrus PDF Preview" and "Office Viewer" are working for me fine, except that some icons are not displayed. In this case, of course, forward and inverse search will not work. I wish the built-in previewer had worked in the same way.

Hooray! Thank you for reporting @ykazakov 🎉

Hello, it works on me too (code-server: v4.20.1, Code: 1.85.2) without any hack but the PDF view doesn't refresh, I need to close the PDF tab and reopen it (refresh all viewers also doesn't work)
