"Unable to install module "upgrade_analysis" because an external dependency is not met: Python library not installed: mako" error when installing the "upgrade_analysis" module in Odoo 16

Question

Hello Odoo Community,

I want to install "upgrade_analysis" module in odoo16, but I got an error "Unable to install module "upgrade_analysis" because an external dependency is not met: Python library not installed: mako"

I use localhost on Windows.
I installed "mako"!
Furthermore, I restarted my odoo_server and I checked every things!

Do you have ideas why odoo16 or python can not find the "mako"

thanks a lot

HI,
Most probably you may have installed the python package in a different python version thats why odoo is not able to detect it.
The case will be as follows:
If you have virtual environment or multiple python versions in the system, you may be installing packages in the default python version of the system.
Instead you have to install the package in the python which uses to run odoo
Thanks
