This is another pc installation failed not sure if the two PCs have the same issue. before i had the code working perfectly for both. now none of them works.

i really appreciate any advice to solve this issue. thank you so much.

I think you have a space in between ‘expo’ and ‘cli’ that shouldn’t be there

try: npm install -g expo-cli
