[solved] Platformio can't find intelhex

[brundage]

I am starting out development for the ESP32 platform with platformio on vscode. When I try to build a basic project I get the following error:

Code: Select all

Generating partitions .pio/build/lilygo-t-display-s3/partitions.bin
Traceback (most recent call last):
  File "/home/brundage/.platformio/packages/tool-esptoolpy/esptool.py", line 41, in <module>
    import esptool

    from esptool.bin_image import intel_hex_to_bin
  File "/home/brundage/.platformio/packages/tool-esptoolpy/esptool/bin_image.py", line 16, in <module>
    from intelhex import HexRecordError, IntelHex
ModuleNotFoundError: No module named 'intelhex'
Compiling .pio/build/lilygo-t-display-s3/FrameworkArduino/Esp.cpp.o
*** [.pio/build/lilygo-t-display-s3/bootloader.bin] Error 1

I have dev-python/intelhex installed. platformio is using the system python.

Code: Select all

0 zippy brundage/.platformio % pwd
/home/brundage/.platformio

0 zippy brundage/.platformio % find . -name python
./penv/bin/python

0 zippy brundage/.platformio % ll penv/bin/python
lrwxrwxrwx 1 brundage brundage 7 Aug  3 11:53 penv/bin/python -> python3*

0 zippy brundage/.platformio % ll penv/bin/python3
lrwxrwxrwx 1 brundage brundage 39 Aug  3 11:53 penv/bin/python3 -> /usr/lib/python-exec/python3.13/python3*

Invoking /usr/lib/python-exec/python3.13/python3 directly works, but not penv/bin/python.

>>> from intelhex import IntelHex

What's going on here? TIA

Found a solution on the platformio forum. (Wow, google sucks these days.)

Remove the $HOME/.platformio/packages/tool-esptoolpy directory and re-open the project in vscode.
