Hi, I installed weasyprint with pip-3.8 install weasyprint (also with pkg install weasyprint), when I try to run it I get:

Code:

Pango is already installed:
Code: 
pkg install pango

Can anyone help me with this?.

I'm running 12.2-RELEASE-p10 without X11 installed.

code is platform- and toolkit-independent.

In which order?

For pip, did you use a normal user account (not root)?

Here, without using pip, a test result, problem-free:

To try again I removed weasyprint, then pkg install weasyprint, after that I run it and got the same OSError: cannot load library 'libpango-1.0.so.0': /usr/local/lib/libpango-1.0.so.0: Undefined symbol "g_memdup2".

Try:
  1. create, activate then boot a new ZFS boot environment
  2. pkg upgrade -f
  3. reboot


Using pip?

Thanks with pkg upgrade -f I got rid of the Pango error, then I installed weasyprint with pip-3.8 install weasyprint because it allows me to install version 53, while using pkg it installs version 51.
