I have been trying to run Odoo in my system but couldnt. I have cloned the repo and am following the steps given in the odoo documentation on their website but its still not running. I was getting module not found errors. So i set up a virtual environment , installed the modules individually there and tried to run it . After that when i try to run it , im getting error in the modules. Please help

enter image description here

The above is the module error im getting. Module name is Lxml. How am i supposed to proceed. ( For installation i tried to run

pip install -r requirements.txt

But i was getting errors in build. So i tried to go module by module. All and any help will be appreciated.
