What is the expected behavior?

When I run gitbook pdf ./ rails-upgrade.pdf, I would expect it to generate a pdf file.

I realize that this might be an issue with PyQt5, but I thought I should reach out anyway. FWIW gitbook serve works perfectly.

Please let me know if you have any suggestions.

Thanks!

As a workaround I'm considering this: https://github.com/GitbookIO/gitbook/issues/1470#issuecomment-238621433

Did you at any point install qt55 with brew?
