Error: no lexer for alias 'markdown' found [Ubuntu based Linux mint xfce]

I am not sure how do I go about fixing these issues...I tried installing glow but then xdg ninja didn't use it.

This is a bit weird, are you able to run glow normally?

I get this error on Debian 11 too.

It says "glow is recommended" but I'm not sure how to install that - it doesn't seem to be in the Debian repository.

Yes I had to compile glow. The only issue being I can only run it through ./glow on the compiled folder in home directory.

You'll have to move the compiled binary to some directory on your PATH, like /bin/ or /usr/bin/.

that fixed it thanks! While I am at it what is this warning about? is that something to do with .bashrc?

[b3nj5m1n]

That means you haven't set the XDG environment variables.

If you want them all at their default location, this probably isn't a huge deal, as almost every program will use the default location as a fallback.

If you did want to set these, you could indeed do it in your .bashrc.

I have the same error and I don't even have glow.

Fine, but the console output says it will work without glow, but it doesn't:

This is a problem with pygmentize, and since I'm not familiar with that tool, I unfortunately can't provide any assistance.

[hmoffatt]

OK it looks like it needs a newer version of pygments. I installed it from pip and now this runs.
