Arduino: arm-none-eabi-g++: no such file or directory

[1cookspe]

I am trying to upload the "Blink" example to my MKR 1000, however I keep getting the same error: "fork/exec /Users/username/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin/arm-none-eabi-g++: no such file or directory". I have installed the SAMD board from the Board Manager in the IDE, and I also updated GCC-C++ on my machine. I am using a Mac on the Mac Arduino IDE. I have also tried uninstalling and reinstalling the Arduino IDE. I tested my MKR 1000 on another computer and it worked perfectly. Any ideas how I can fix this?

You probably need to reinstall the SAMD package from board manager since the compiler didn't extract properly. In the worst case you can delete /Users/username/Library/Arduino15/packages/arduino folder and then reinstall the core

~Same problem here with the SAMD board package from the Board Manager and on Mac as well.~
~@facchinm What do you mean by reinstall the core?~
Ok found my solution on Adafruit forum:
I needed both the Arduino SAMD and Adafruit SAMD packages for the Adafruit Playground Express to work.
