Installing frescobaldi in a virtual environment

[nvictor]

Hello all,

I ran into this issue running frescobaldi 3.1.3 on my Linux machine (Pop_OS / Ubuntu 22.04 / Jammy)

Traceback (most recent call last):
  File "/usr/share/frescobaldi/frescobaldi_app/qpageview/highlight.py", line 209, in paintEvent
    super().paintEvent(ev)  # first paint the contents
  File "/usr/share/frescobaldi/frescobaldi_app/qpageview/shadow.py", line 43, in paintEvent
    rect = ev.rect().adjusted(-width, -width, width / 2, width / 2)
TypeError: adjusted(self, int, int, int, int): argument 1 has unexpected type 'float'

After looking through the issues, releases, comments, I decided to contact the Ubuntu package maintainers here

Sounds like frescobaldi 3.2 is not going to be released for Jammy. So I decided to install frescobaldi using a virtual environment. But I am unable to install python-poppler-qt5.

I am getting this error:

I was wondering if anyone who has been successful at installing frescobaldi in a virtual environment can share a mininum requirements.txt file?

Thank you.

Try upgrading pip according to this answer: https://stackoverflow.com/questions/65447314/attributeerror-module-sipbuild-api-has-no-attribute-prepare-metadata-for-bui

Or simplify your life and install Frescobaldi from Flatpak.

I tried upgrading pip. I will look into Flatpak. Thank you!
