"No module named 'intelhex' compile error" - unable to permanently delete the tool-esptoolpy folder

Complete newbie here…

When trying to Upload from PIO to an ESP32 I get same the error others have had:

ModuleNotFoundError: No module named ‘intelhex’

The solution of deleting C:\Users\<user>\.platformio\packages\tool-esptoolpy does not work for me:

Each time I delete the folder, and click Build or Upload, the folder re-appears and the error re-occurs.

I tried re-installing VSC / PIO and to running a simple flashing LED script, and I always get the same error.

Any advice or tips would be greatly appreciated.

Reinstalling VS Code or the plugins won’t help here as they are just the “GUI”.

  • Close VS Code
  • Delete the folders C:\Users\<user>\.platformio\packages\ and C:\Users\<user>\.platformio\frameworks
  • Start VS Code and open your project
  • Wait until PlatformIO installed the missing files

You also might to use a newer platform version which is available by pioarduino’s platform-espressif32:

platform = https://github.com/pioarduino/platform-espressif32/releases/download/stable/platform-espressif32.zip

Thanks for the response Sivar. Unfortunately I followed your suggested steps without success (same error appears). Not sure if it is me being thick or PlatformIO having a bug.

The framework folder ‘framework-arduinoespressif32’ (the one I believe you told me to delete) is within the ‘packages’ folder’. I tried deleting both, without success and I also downloaded and saved the pioarduino’s ‘platform-espressif32-main’ folder into the ‘packages’ folder whilst deleting the tool-esptoolpy and framework-arduinoespressif32 folders, but this did not work either.

When re-opening VS Code it did the following, and then “an unexpected error occurred”:

Does that show the problem?

Apologies for my lack of basic understanding…

This isn’t “basic” stuff. This is the “most advanced stuff” :wink:

If this doesn’t help, try reinstalling platformio completely by deleting the whole .platformio folder.

Thanks Sivar, this solution worked. I had to get someone to explain how to input those commands, and there was an issue with the space in my Users account name, but using quotation marks fixed that.

Oh yeah…space in username is a “bad thing” :wink:

In this case another option is to change PlatformIO’s core directory to different location (path without a space) by setting the (Windows) environment variable PLATFORMIO_CORE_DIR before (re)installing PlatformIO
