问题
I am getting this error when I try to create a project in console.developers.google.com. I have 8 more projects left in my quota. I have tried different names and different project IDs. When I hit the "retry" button it shows the error after some time again.
UPDATE [Oct 9, 2017]: It looks like Google fixed the issue, since I was able to create a new project today.
回答1:
I went ahead and attempted to create a new project in the Google API, and received the same error. This has occurred before with the Google API and is considered a temporary issue, often being fixed the same day. But if I remember correctly they have had it down longer in the past.
So the good news is, it's not something that is on your end, the bad news is, it's on Google's end.

If your google account is a Google Apps account (Google Suite, Google Apps, Gsuite, or whatever the Marketing folks are calling it these days), then you need to enable "Google Developers Console".
- Login as an admin to admin.google.com
- Go to Apps > Additional Google services
- Find the "Google Developers Console" line item and set to "ON for everyone" (or whatever).
That should do it.
