FW build error - error compiling _builtin_port_view.py

[yulin0826]

Hi all,
First of all, thanks for reading this discusstion content. I'm a newbie to build the my owned firmware.
I trying to build the FW in Windowns Cygwin enviroment and follow the SOP, most of steps are works welly.
But finally got error as below, does anyone knows how to fix it ? If I removed all files in \bricks_common\modules folder than that can bulid the FW successfuly, but beause I need build the custom .py module into FW so would like to seek any method can fix it. Appreciate it !

error message

I would suggest building using WSL instead of Cygwin. We don't normally build on Windows, so it might not be working due to something platform-specific.

Thanks for that suggestion, I'll trying WSL !

After switch to WSL the issue can be fixed, thanks !

Thanks for @dlech recommendation by using WSL tool and it work very well, here would like to consult one more thing.
I can build with my custome .py module file in FW but Pybricks Code (Web IDE) only can reconize native module/function to do the autocompletion & InteliSense function because the IDE doesn't know what custom module has build into. How could I can add my custom module/pacake/function structure in Pybricks Code (Web IDE) autocompletion & InteliSense list ? Is it need to build my owned local web IDE server or just modify (or add) in some certain file to have that function ?
I'm not prefer to use Visual Studio Code to coding becuase the enviroment is unfriendly for young kid (3rd ~ 6th grade), so still prefer using Pybricks Code IDE and seek for easier mothod to add custom module into autocompletion & InteliSense list.
Appreciate again ~

Yes, you would need to create your own fork of Pybricks Code to get the code completion to "just work".

If we get really creative, maybe we could figure out a way to make .py file in Pybricks Code that just contains type hints.
