Answer 1

Probably there are programs in your systems that uses older version of pango library and their bin folders are in PATH. You can try to run console and set path to e.g. C: with:

set path=C:

and then run you program in the same console. If this helps, you are on the right way and just need to find which directory in PATH causes this error.

For me these poblem-causing programs with older libraries were xmlsec1 and graphviz.

Answer 2

1. You have to set your system PATH as described here (change it with the correct gtk folder on your system)

set WEASYPRINT_DLL_DIRECTORIES=C:\GTK3\bin;

2. Ensure that Graphviz is not installed in your system (it was, in my case) as mentionned here

WHERE fontconfig.dll

If it is the case unsintall Graphviz en ensure it is not referenced in system PATH
