Python ImportError when compiling Odrive Firmware

[ChnTamap]

Hi, I am encountering a Python error while compiling the firmware

Describe the bug

PS E:\Project\Libraries\Odrive\Odrive\Firmware> make
board version: v3.6-56V
Firmware version 0.5.6-dev (fw-v0.5.6-1-g58fdd3fd*)
 [     ] 100%
Traceback (most recent call last):
  File "E:\Project\Libraries\Odrive\Odrive\tools\create_can_dbc.py", line 1, in <module>
    from cantools.database import *
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\cantools\__init__.py", line 9, in <module>
    from . import j1939, logreader, tester

    import can

    from . import broadcastmanager, interface
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\can\interface.py", line 12, in <module>
    from .bus import BusABC
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\can\bus.py", line 25, in <module>
    from typing_extensions import Self
ImportError: cannot import name 'Self' from 'typing_extensions' (C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\typing_extensions.py)
make: *** [Makefile:36: all] Error 1

To Reproduce

cd Firmware
make

Desktop

• OS: Windows 10
• odrivetool Version : ODrive control utility v0.6.7 (unused)

The .elf file has been successfully compiled, but I still want to ask how to resolve this issue. My software versions: Python 3.9.5, cantools-39.4.0 Do I need to install a specific version of Python or cantools? Or do I need to modify which code?

Thank you!

From a quick search, it could be that your typing_extensions is too old, so try

pip3 install --upgrade typing_extensions

If that doesn't work, you can try to downgrade cantools:

pip3 install uninstall cantools
pip3 install "cantools<39.0.0"

Thank you! I upgrade the typing_extensions, a new problem has emerged (at create_can_dbc.py:15). then I downgraded cantools and build successed. Thanks again.
