Hi,

There are so many modules which contains external dependencies, you cannot go in each modules' __manifest__.py file and check for the external dependencies. As such when you try to install that particular module, it will ask that there is no external dependencies installed, you can just install it from putty or Prompt (Whatever interface you are using) and also it should be same interface where your python is installed, I mean the same environment (No need to have same path of dist_packages.) You can install from this command:

pip install <external_dependency_package_name>

Also if there is some special external libraries, it should installed different way, you can google it for that or use the readme.txt file from that particular module.

(Other python packages for odoo can be installed from odoo / requirement.txt file. for that command is :

pip install -r requirements.txt  ;; it is also there in odoo installation guide, in case if you need it.)

Thanks,
