Running SolidOs on Apple M1 chip 16.09.21

  • currently SolidOS needs node 12.19.1 and node 13.14.0 but M1 chip cannot install node < v14

Solution:

  • on MacOs terminal one can switch the architecture used to build code, you need to switch to -x86_64 with the command: $env /usr/bin/arch -x86_64 /bin/zsh —-login
  • to check if it worked check with arch command in the terminal, the result should show i386
  • afterwards you can proceed to install other node versions: nvm install 12.19.1 and nvm install 13.14.0
