I have a ESP32 and I've been trying to flash it with the Arduino IDE, however it's been giving me Python error messages :/ when I'm trying C/C++ code to flash the Arduino.


How can I setup the board below so I can flashi it with C/C++ from the Arduino IDE?

Error Message:

  • Arduino Version: Version 2.0.4-nightly-20230119 CLI Version: 0.29.0

  • The error message says "...Mac OS X 11.0...". Is that the version of OS X you are using? Can you tell us what version of the IDE you are using?

  • And what do you conclude? The library was built for 11.0 but you have 10.13... Did you try to use a version of the Arduino IDE for your OS? Commented Feb 13, 2023 at 8:46
  • You might want to re-read the referenced tutorials. Disclaimer: I don't have a Mac and no ESP32 at hand, but know a bit about general computer science and used the Arduino IDE for different targets. Commented Feb 13, 2023 at 9:30

I don't have Mac but I am working on Linux and I also had issues with Arduino IDE v2 (in the past). Because of this I'm still using IDE v1 with no issues and that's my suggestion: try older version of the IDE on your mac, you can still download it. If it won't work you can turn to PlatformIO or VSCode IDEs.
