Class 'Google\Auth\OAuth2' not found

Question

I was trying to add google plus login to my web but I encountered this error which seems really weird because I have the file already added. I already enable vendor/autoload (Im using codeigniter)

Anyone had this kind of error before? How did you fix this?

A PHP Error was encountered

Severity: Error

Message: Class 'Google\Auth\OAuth2' not found

I assume you are using this package. Did you install it via composer ? It has several dependencies and it looks like based on the error, that you may be missing some of them.
