Как интегрировать Magento с OpenERP v8 (Odoo)

Как интегрировать коннектор Maganto с OpenERP v8 (Odoo).

Я пытаюсь установить его, но он вызывает ошибку ниже. Я также пробовал это с путем addons.

The `web` module is provided by the addons found in the `openerp-web` project.
Maybe you forgot to add those addons in your addons_path configuration.
