Are there no error messages (in vim's bottom line)?

I had something similar here, with an error complaining about the bibliography not being generated. I added a .bib file and an example \cite{SomeKey} and it worked.

[vkhodygo]

I have similar problems with Fedora. What details do you need?

[Newexplorer]

Check what version of python you have installed. I think the plugin doesn't work with python3.

[vkhodygo]

I use both versions, however, v2 is my system default as it is everywhere else. Nevertheless, it shouldn't be an issue since the plugin checks python versions before starting.

Experiencing the same problem with NeoVim after updating the Plugin after about 8 months.

[RedBorg]

Experiencing same problem also with evince, pdflatex, neovim and arch, fresh plugin install (with vim-plug) with no configs.

[xuhdev]

Folks, I really cannot reproduce this issue here. Have you tried with only this plugin enabled? It can be some conflict but I really don't know.

[ghost]

Same issue, on Manjaro with gvim. Did anyone figure it out? I'll try with just this plugin alone now.

As with other similar issue reports, the document compiles fine via other means.

I had tried it with both vim-plug and pathogen, but as I've been having problems with both (and yay with AUR packages*), I decided just to plop it into .vim/plugin/,

The relevant errors are:

Initial compile...
Error detected while processing function UpdatingToggle[2]..LaunchMuPDF:
line 18:
Compilation failed; the PDF does not exist.
Live updating preview now ON.

And :LLPStartPreview: Failed to compile And: cat: home/tunurit/.config/live-latex-preview/lastresult: No such file or directory With a pdf compiled via other means, I just get:

PDF preview now on.
Live updating preview now ON.

with the same lastresult file missing.

E1: I have both mupdf and zathura with the relevant mupdf backend.

@dumuzidsafi Thanks! Can you show what's in your ~/.config/live-latex-preview/?

The part really help me out is: Before you actually start the live view, make sure you have started a tex document. So these lines are pretty what you have to have:

\documentclass{article}
\begin{document}

\end{document}
