WeasyPrint needs the Pango, cairo and GDK-PixBuf libraries. They are part of GTK+ (formerly known as GIMP Toolkit), and must be installed separately.
After installing GTK+ libraries, do :
python -m weasyprint http://weasyprint.org weasyprint.pdf

Installing GTK+ didn't work for me. I solved this problem using UniConverter2.0. My environments is
- Python 3.7
- Windows 10 x64
- Install uniconvertor-2.0rc4-win64_headless.msi,
- Find the "dll" sub-directory under the UniConverter installation path.(In my case,
C:\Program Files\UniConvertor-2.0rc4\dlls
) - Add this "dll" path to the system path.
- Close VSCode and reopen the project.
- Try to run the server again. Enjoy!

Starting from Python 3.8, dll's need to be added separately. Added GTK+, MSYS2, Visual Studio C Compiler and Uniconverter. But, nothing seemed to work. Finally, got it working after putting the script for calling add_dll_directory.
import os
def set_dll_search_path():
# Python 3.8 no longer searches for DLLs in PATH, so we have to add
# everything in PATH manually. Note that unlike PATH add_dll_directory
# has no defined order, so if there are two cairo DLLs in PATH we
# might get a random one.
if os.name != "nt" or not hasattr(os, "add_dll_directory"):
return
for p in os.environ.get("PATH", "").split(os.pathsep):
try:
os.add_dll_directory(p)
except OSError:
pass
set_dll_search_path()
