Error: exec: “/bin/avr-g++”: file does not exist Compilation failed.

Compilation failed Command `C:\Program Files\XOD IDE\resources\arduino-cli.exe --config-file=C:\Users\mauri\AppData\Local\Temp\arduino-clieFzh7O\.cli-config.yml compile --fqbn arduino:avr:uno --verbose C:\Users\mauri\AppData\Local\Temp\xod_temp_sketchbookygEkMa\xod_1543638617334_sketch` failed with code 1 The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers.

Please help I can’t upload to arduino.
