can anyone provide the steps (in detail) to solve this issue?

"message": "Access Not Configured. The API (Drive API) is not enabled for your project. Please use the Google Developers Console to update your configuration.",

I'm sure this is the problem, but how to solve it has become a nightmare for me.
