在 Odoo 12 中安装外部模块时出错

Question

I am trying to install OCA external department module on Odoo 12 with demo data. When in the applications menu I select this module and click on the install button, I receive the following error. Sorry for my english. I have the latest version of python installed.

Answer 1

You are trying to install a module crm_department from OCA v8 in odoo v12 where the use of the openerp.osv is deprecated. you should migrate the module code to v12 using the new API then you will be able to install the module.
