SyntaxError: future feature annotations is not defined

[H-Y-H-Y-H]

I was using this package and it worked perfectly. Now I have some trouble because I re-install the latest version which has "from future import annotations" in both board.py and chip.py files.

Below shows the error I got:

Traceback (most recent call last):
  File "servo_motor.py", line 1, in <module>
    from adafruit_servokit import ServoKit
  File "/home/nvidia/Desktop/face_env/lib/python3.6/site-packages/adafruit_servokit.py", line 35, in <module>
    import board

    ^
SyntaxError: future feature annotations is not defined

I solved this by copying the previous version code.

adafruit-blinka is now requiring Python 3.7. This library should also be requiring 3.7.

Which board and OS are you using that only has Python 3.6? Are you able to upgrade?

It says nvidia, so maybe it's a Jetson Nano or something. I think the crux of this is that PlatformDetect is currently set to 3.6 as the required version, but actually requires a feature from 3.7.

I had similar problem. How about installing old version compatible with python 3.6.9? or will installing python 3.7 affect working with opencv negatively, is it necessary to update old opencv files?

@yulu54 Hi, How did you solve this? I'm trying to install older versions of adafruit-circuitpython-ads1x15 and it has the same error. I don't understand how older version has the same error. I tried installing even the oldest versions with pip3 and still the same errors. I have python3.6.9 in a container and It caused other issues upgrading python. Thanks for your answer!

I got past some of these issues with adafruit-io by forcing a lower version of setuptools-scm with pip install setuptools-scm==6.0.1 hope this helps someone
