PyInstaller does not include dependency file

Question

I'm trying to create an use PyInstaller in my project.

This project uses weasyprint but when I run pyinstaller, it fails because weasyprint's resource files seems not being installed.

Traceback (most recent call last):

Is there a way to force pyinstaller including this file ?

Shall I include it by myself ?

Command : pyinstaller mainwindow.spec

mainwindow.spec :

# -*- mode: python -*-
a = Analysis(['mdedit/mainwindow.py'],
             pathex=['/home/sylvain/git/md-edit'],
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='mainwindow',
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name='MdEditor')

Thanks in advance.

I've had a similar problem, possibly the same one, and solved it as follows. Hope it works for you:

# -*- mode: python -*-

from PyInstaller.utils.hooks import collect_data_files

w = collect_data_files('weasyprint')
ww = []
for k,v in w:
    ww.append((k, v.split('weasyprint/')[1]))
added_files += ww
added_files += collect_data_files('pyphen')
extra_imports = ['pyphen', 'weasyprint']

a = Analysis(['mdedit/mainwindow.py'],
             pathex=['/home/sylvain/git/md-edit'],
             datas=added_files,
             hiddenimports=extra_imports,
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='mainwindow',
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name='MdEditor')
