Problems with installing on my MacOS: please help

[tsmitsmitonline]

I installed Scripted on my MacOS. Command in terminal:

curl -s https://raw.githubusercontent.com/koush/scrypted/main/install/local/install-scrypted-dependencies-mac.sh > ~/install-scrypted-dependencies-mac.sh
bash ~/install-scrypted-dependencies-mac.sh
rm ~/install-scrypted-dependencies-mac.sh

Gives this result with errors....
