[tryton-es] Instalando htlm_report / Babi en Tryton 4.4 con error en "weasyprint"

[Favio Dutria]

Buenas tardes.

Hago estas lineas para ver si alguien me puede ayudar. Estoy en Tryton 4.4
e instalando BABI que tiene como dependencia la librería "weasyprint".
Al intentar instalar dicha librería median pip install weasyprint me da el
error:

Collecting weasyprint
Using cached WeasyPrint-0.42.2.tar.gz
Complete output from command python setup.py egg_info:
error in WeasyPrint setup command: Invalid environment marker:
python_version < "3.0"

Actualmente estoy ejecutando python 2.7.
Debo si o si migrar a Python > 3.0 o existe alguna versión de weasyprint
compatible con Python 2.7?

Desde muchas gracias,
Favio Dutria

Muchas gracias, en mi caso tuve que hacer lo siguiente:

sudo pip install --upgrade cffi
sudo pip install weasyprint==0.41

Con esto me funciono, lo copio por las dudas que alguien mas tenga el mismo
problema.
Estoy con instalación Debian bajo la distro LMD2 Betsy

Saludos,
