Getting this Error at step 11 or step 12 after running "meteor npm install" and "meteor"

Hello there! how are you doing?
Wich version of meteor are you using ?
Does this happen when you use this folder from the repo? step11.
Tried in my machine running the same commands meteor npm i then meteor and it did compile.
Can you provide more info?
