Can’t compile Arduino Sketch for Unihiker K10 on Intel Mac using Arduino 1.8.19 IDE
CLC_3473 2025-08-20 07:54:23 779 Views5 Replies I did a portable installation of Arduino IDE 1.8.19 on a Mac Mini using this approach: https://forum.arduino.cc/t/portable-version-imac/518411/5. Then I added this URL to the additional boards manager URLS: https://downloadcd.dfrobot.com.cn/UNIHIKER/package_unihiker_index.json and selected “unihiker k10’ as the board. However, when I tried to compile the “screen color” sketch for K10, I got this error: bash: {runtime.tools.esptool_py.path}/esptool/3.0.1: No such file or directory
exit status 127
/Users/xxx/Dropbox/Arduino_1.8.19/Arduino.app/Contents/Java/arduino-builder returned 127
Error compiling for board unihiker k10.
I have the same Problem on a Macbook M1 with Sequoia 15.6.1 and Arduino 2.3.5 and Unihiker 0.0.2
…… /UNIHIKER/tools/esptool_py/4.6/esptool/3.0.1: Not a directory

CLC_3473 We have just update our Arduino IDE SDK into V0.0.2. Now K10 support Arduino IDE V2
Would you update the SDK and use Arduino IDE V2 to try?
Good to know that Arduino IDE V2 is now supported! However, using IDE 2.3.6 and Unihiker V0.0.2, I still get a similar error:
bash: /Users/chriscunningham/Library/Arduino15/packages/UNIHIKER/tools/esptool_py/4.6/esptool/3.0.1: Not a directory
exit status 126
Compilation error: exit status 126
Can you tell me the system version running on your Mac mini? We will find a Mac with an Intel chip for testing.
