Python external_dependencies：“ google-cloud-pubsub”无效

Question

Environment details Google cloud pubsub window 10 Python version: 3.6.3 google-cloud-pubsub version: 0.39.1 Steps to reproduce I used google-cloud-pubsub in Odoo module. I tried to explain the issue in step by step.

Added 'google-cloud-pubsub' in external_dependencies in python manifest file:

"external_dependencies": { 'python': ['google-cloud-pubsub'] },

Expected result: Actually, I don't know why this error occurs. Normally it will be work.

Actual result: When I published python module to Odoo server its threw below error:

odoo.exceptions.UserError: ('Unable to install module "caliva_wsp" because an 
   external dependency is not met: No module named google-cloud-pubsub', '')

How to solve this issue? I already stuck at this point around 3 days. Thanks!

This error message is the expected result if you have not installed the dependency. Odoo module manifest external dependencies only check that the external module is available from Odoo code. It does not install the module.

Install google pubsub pip module on your Odoo server with command pip3 install google-cloud-pubsub before installing your own Odoo module. After that your module should be installable.

You can also automate the installation of dependency by putting it in module requirements.txt file. More information on this can be found at https://www.odoo.com/documentation/user/12.0/odoo_sh/getting_started/first_module.html#use-an-external-python-library .
