Answer 1

Installing GTK+ didn't work for me. I solved this problem using UniConverter2.0. My environments is

• Python 3.7
• Windows 10 x64

1. Install uniconvertor-2.0rc4-win64_headless.msi,
2. Find the "dll" sub-directory under the UniConverter installation path.(In my case, C:\Program Files\UniConvertor-2.0rc4\dlls)
3. Add this "dll" path to the system path.
4. Close VSCode and reopen the project.
5. Try to run the server again. Enjoy!

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
