SyntaxError: future feature annotations is not defined

Question

I am try to run code

sh run.sh

and it showed me the error

File "/anaconda3/envs/_galaxy_/lib/python3.6/site-packages/filelock/__init__.py", line 8
    from __future__ import annotations
    ^
SyntaxError: future feature annotations is not defined

I saw some solutions indicated that I need to update my python version, but I am in a python verion 3.9.7.

(py39) KedeMacBook-Pro:~ ke$ python --version
Python 3.9.7

However, in the error code it showed a python veriosn of 3.6. So, I am not sure where went wrong. Why it is not using the python envrionment that I have? Please help, thank you.

`from __future__ import annotations` is only available from Python3.7 — Iain Shelvington, Dec 29 '21 at 04:41

Based on the error, it looks like your code is using Python 3.6 and not Python 3.9. This import is available starting from Python 3.7. Check run.sh to make sure it is referencing the right python interpreter.

I'd also recommend using a virtual env using the python version you require and running your script inside that.

Thank you so much, it worked after I created the virtualenv. This error troubled me for weeks, thank you for save my day. haha – keee Jan 04 '22 at 16:15
@keee not a problem :) – niranjan94 Jan 04 '22 at 17:51
I did that and now I have a different error module 'packaging.version' has no attribute 'LegacyVersion' – KansaiRobot Dec 12 '22 at 04:22
