I'm trying to run my react native code from a github repository on ubuntu by using npm start and expo. When I run npm start I get the follow error:

"Cannot determine which native SDK version your project uses because the module expo is not installed. Please install it with yarn add expo and try again."

I have tried the 'yarn add expo' but that doesn't seem to work because I can't get yarn to work and it doesn't recognize 'add'. I haven't found anything on this problem either. Does somebody know what is going on?

Try npm install expo instead of yard add expo.

Note: yarn is another package manager just like npm. If you have npm installed already then you can replace yarn add with npm install always.
