pyrebase4 AttributeError: 'function' object has no attribute 'sign_in_with_email_and

I couldn't make a login screen with pyrebase4. I'm getting this error:

AttributeError: 'function' object has no attribute 'sign_in_with_email_and_password'

Creating user is also not possible and it gives the error:

AttributeError: 'function' object has no attribute 'create_user_with_email_and_password'

I'm using pyrebase4 since I read that the original pyrebase was discontinued. I saw more than one video of people just writing the code exactly like I did and theirs seem to just work. I don't understand why mine doesn't.

CodePudding user response：

I think your code:

auth = firebase.auth

should be:

auth = firebase.auth()

Note the parens.
