AttributeError: 'module' object has no attribute 'environ' on MicroPython and an ESP32

Hello,

I was trying to replicate one of the examples from the "adafruit/Adafruit_CircuitPython_SHTC3" repository in the REPL, but when I imported the "busio" module I got an error from the adafruit_platformdetect/chip.py file which returned this traceback:

  File "<stdin>", line 1, in <module>
  File "/lib/busio.py", line 17, in <module>
  File "/lib/adafruit_blinka/agnostic/__init__.py", line 18, in <module>
  File "/lib/adafruit_platformdetect/chip.py", line 69, in id
AttributeError: 'module' object has no attribute 'environ'

It seems like it comes from the line number 69 in that file where the script tries to access the os.environ attribute, which also doesn't appear when I list them:

>>> import os
>>> dir(os)
['__class__', '__name__', 'remove', 'VfsFat', 'VfsLfs2', 'chdir', 'dupterm', 'dupterm_notify', 'getcwd', 'ilistdir', 'listdir', 'mkdir', 'mount', 'rename', 'rmdir', 'stat', 'statvfs', 'umount', 'uname', 'urandom']

I'm currently using the "ASDelivery ESP32 NodeMCU" with an ESP32-WROOM-32 on it which is running the prebuilt firmware from the official website named esp32-idf4-20210202-v1.14.bin.

And the modules I installed are the following:

• adafruit-circuitpython-bundle-py-20210225 (partially)
• Adafruit_Blinka-6.2.2
• Adafruit_Python_PlatformDetect-3.1.1
• Adafruit_Python_PureIO-1.1.8

Is this normal or is it a bug, I haven't seen any mention of this error anywhere ?

yeah it probably isnt working on micropython due to pretty much nobody using it outside of linux. wanna try patching/fixing the library to see if it can be re-worked for micropython?

I've also got the exact same issue.
I'll try and have a look at it.
In the meantime do you know if previous versions also have this issue?

[ladyada]

its probably been broken for a long time :D
