Please upgrade Markdown PDF to ver1.4.3 and try.

[vituslehner]

I'm afraid I am still getting the above error in WSL Ubuntu, using v1.4.4.

[jacknbeans]

I was getting a very similar issue and was able to fix it by installing dependencies that puppeteer needed that were missing on my WSL installation. So I was able to solve it by apt-geting some packages. The specific calls that I made were this:

sudo apt-get update
sudo apt-get install gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps xvfb

I got this from this issue on puppeteer: puppeteer/puppeteer#5468

If I had the error I would paste it here as well, but unfortunately I just fixed it and I don't want to unfix it to show the error. However, I do know that the one dependency it was complaining about was libnss3 (which is in the long list of dependencies above). Not sure if that was the only one that was missing or not, but maybe someone else can do some more debugging on this issue to find out if there are other dependencies required.

[alanwunsche]

On v.1.4.4 in VS Code . Mac OS

I get the following new errors today:
Error: ENOENT: no such file or directory, open
(it includes my file and '_tmp.html' appended to the end)

followed by

ERROR: exportPdf()

Error: net::ERR_FILE_NOT_FOUND at file:///Users/....

Anyone else experiencing this new error? It was working fine before but seems to have just started throwing errors.

I was experiencing this same issue in a new WSL 2 install with Ubuntu running v 1.4.4 of this extension and the above solution worked for me.

The exact error I received leading me here in case this helps further track this issue was:

Error: Failed to launch the browser process! /home/collint/.vscode-server/extensions/yzane.markdown-pdf-1.4.4/node_modules/puppeteer-core/.local-chromium/linux-722234/chrome-linux/chrome: error while loading shared libraries: libXcursor.so.1: cannot open shared object file: No such file or directory TROUBLESHOOTING: https://github.com/puppeteer/puppeteer/blob/master/docs/troubleshooting.md

i had this same error trying to export to pdf from a dev-container based on mcr.microsoft.com/vscode/devcontainers/dotnet:0-6.0-bullseye-slim, but that apt-get install command failed with a message E: Unable to locate package libappindicator1

i just removed libappindicator1 from the long list and it worked:

$ sudo apt-get install gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libnss3 lsb-release xdg-utils wget x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps xvfb

now it works!

this leads me to suspect that more in that long list of things to install could be removed, but i haven't the inclination to go through it.

The following sufficed for me (Windows 10, WSL2, Ubuntu Focal):

sudo apt install libxdamage1 libcups2 libatk1.0-0 libatk-bridge2.0-0 libgtk-3-0

[SergeiYevteyev]

Faced the same issue on Windows 11 (WSL2)

Actually it is not an issue of an extention. The problem here as many have pointed is with missing packages.

What you have to do is to look at error message in VSCode.

The error message is quite generic

In my case it states that I'm missing lib libgtk-3.so.0
And it also shows location of chrome that is used to render html
"/home/[youruser]/.vscode-server/extensions/yzane.markdown-pdf-1.4.4/node_modules/puppeteer-core/.local-chromium/linux-722234/chrome-linux/chrome: error while"

What's next
run sudo apt install -y libgtk-3-0

Then you have to validate that package installation have fixed the issue
One way is to generate your pdf/html again

Or you can use terminal to validate that chrome is ready to be used
copy path with chrome location
and run following command
ldd /home/[youruser]/.vscode-server/extensions/yzane.markdown-pdf-1.4.4/node_modules/puppeteer-core/.local-chromium/linux-722234/chrome-linux/chrome | grep not

When there are missing dependencies output will look similar to this
libgtk-3.so.0 => not found libgdk-3.so.0 => not found
If all is good output will be empty.

No matter which way you will use to find out which dependecies are missing, just follow the error message to find out all dependencies that are missing. Happy dependencies hunting :)

in my case I had to install
sudo apt install -y libxdamage1 libnss3 libcups2 libxss1 libasound2 libatk1.0-0 libatk-bridge2.0-0 libgtk-3 libgdk-3 libgtk-3-0

and that solved pdf generation issue.

I switch to the Windows version of VS Code, reinstalling Markdown PDF, and then generate the HTML from there.
