In this question, the setup of LaTeX in VS Code is explained in one of the answers. I followed the instructions, and am indeed able to compile a LaTeX document in VS Code, with the PDF output as expected in the same folder.
However, the preview of the PDF is not working. (Update: it is working, but does not update if the file is compiled again.)
I am using: LaTeX Workshop 8.7.2.
Upon choosing "view PDF file", the message
command 'vscode.preview.Html' not found
pops up in the bottom right.
I searched online, and found here that I should open the complete folder and not the .tex
file, which I followed, but to no avail. It also suggests that the feature is no longer existing due to a software change.
When I disable the preview plugin, ctrl + shift + b compiles, but ctrl + alt + v does not.
How can preview the PDF file in VS Code? Is there another extension that should be used? I am not sure if LaTeX Workshop is supposed to bring its own PDF viewer, but at least for me, it is not working.

The PDF-file in the directory is correctly created and updated.
Entries in the Console:
Only these appear upon running pdfLaTeX. They seem to be only some errors relating to Python (I previously ran a python program in a different folder than the one with my LaTeX documents).

It seems to be searching in the subfolder build
, how can I change this? I found this question, which seems related, but it doesn't help.
This is the settings.json
file in the folder .vscode
in the folder in question:
{
"cSpell.enabled": true,
"editor.cursorBlinking": "solid",
"editor.wordWrap": "on",
"editor.wordWrapColumn": 80,
"editor.wrappingIndent": "same",
"latex-workshop.latex.outDir": "./build",
"latex-workshop.view.pdf.viewer": "tab",
"latex-workshop.latex.autoBuild.cleanAndRetry.enabled": true,
"latex-workshop.latex.autoClean.run": "onBuilt",
"latex-workshop.latex.clean.subfolder.enabled": true,
"latex-workshop.latex.clean.fileTypes": [ "*.aux", "*.toc" ]
"latex-workshop.debug.showUpdateMessage": false,
"telemetry.enableCrashReporter": false,
"telemetry.enableTelemetry": false,
"python.pythonPath": "C:\\Users\\me\\AppData\\Local\\Programs\\Python\\Python38\\python.exe",
"python.linting.pylintEnabled": true,
"python.linting.enabled": true,
"restructuredtext.confPath": ""
}
Deleting the line "latex-workshop.latex.outDir": "./build",
worked.
Sadly, the PDF viewer does not update when the LaTeX file is compiled.
I added the bottom three lines:
{
"version": "2.0.0",
"tasks": [
{
"label": "Run pdflatex",
"type": "shell",
"group": {
"kind": "build",
"isDefault": true
},
"command": "pdflatex",
"args": [
"-interaction=nonstopmode",
"-file-line-error",
"_CFA.tex"
]
},
{
"label": "Run bibtex",
"type": "shell",
"group": {
"kind": "test",
"isDefault": true
},
"command": "bibtex",
"args": [
"-terse",
"*.aux"
]
},
{
"label": "update pdf",
"dependsOn": "build",
"command": "${command:latex-workshop.refresh-viewer}"
}
]
}
to the tasks.json
file, as suggested here, but to no avail.
To see where a problem could be located, following this site, in the file settings.json
, I added this line:
"latex-workshop.view.pdf.zoom": "page-fit",
And indeed, upon opening the PDF preview in the VS Code tab, the fit is adjusted to page fit.
perl -v
at the command prompt)?
