Hi, I'm trying to use the mdpdf but I'm facing the issue above.

My versions are
node: 15.5.1
npm: 7.10.0
mdpdf: 2.1.2

Any clue what might be happening?

Thank you

Seems like a problem in showdown-highlight dependency.

Same problem here.

I could make it work using a fixed version:

npm install [email protected] -g

[Flou21]

same, with fixed version it worked
