AttributeError: ParaFrag instance has no attribute 'underline'

[Massimo]

This is Trac 1.2.3 I just installed the TracWikiPrintPlugin without any configuration and received:

 Trac detected an internal error:

AttributeError: ParaFrag instance has no attribute 'underline'

Is there any minimal configuration I need to produce a PDF export?

That's an xhtml2pdf issue. Try to downgrade reportlab to 3.4.

See ​xhtml2pdf is not compatible with reportlab 3.5.x · Issue #404 · xhtml2pdf/xhtml2pdf.

I tried:

$ pip2.7 uninstall reportlab

But now I get:

Why you're installing reportlab-x? That should be reportlab.

[Massimo]

Because I thought this is the name for the 3.4 version you mentioned. How do I install the right version?

I did, but now pip check complains about missing reportlab:

$ pip install --user "reportlab < 3.5"

Use pip2.7.
