Adafruit_NAU7802 will not compile in Arduino 1.8.12 (MaxOS X)

[Maneki9Neko]

When I cut and paste the code Adafruit_NAU7802 into the Arduino IDE version 1.8.12 (MaxOS X) and run the 'verify' routine I receive the following error code: test_sketch_NAU7802:57:16: error: 'class Adafruit_NAU7802' has no member named 'calibrate'

1. Does anyone else have the experience that this code will not compile?

2. Typically when I cut and paste provided code into the IDE, it compiles without difficulties.

3. I am a Newbie, and if this is not the correct forum for this query, I apologize. I would be very grateful for any guidance on how to resolve this. or where to obtain code that will compile.

Thanks

Robert

Here is the full error code:

something is amiss with your installation, the funciton is there
https://github.com/adafruit/Adafruit_NAU7802/blob/master/Adafruit_NAU7802.h#L94
you should not be cutting and pasting, install the library thru the IDE and run the example. see the guide for more info

I did install the library through the IDE.
This said, it is very helpful to know that the problem here is probably with the IDE and not with the library itself.
Later:
SUCCESS! I reinstalled the library and the code compiles Thanks very much for helping me locate the source of this problem. Oh, and the PGA is absolutely key to making these things run right. Thanks so much for writing this code.
