  <p>I've tried reinstalling expo with npm and yarn, but i cant get it to work.  I looked and saw in the package.json file the 'main' key has a value of 'node_modules/expo/AppEntry.js'. Before this happened i was having trouble with expo that it told me that expo cant be recognized so i messed around with environment variables until it worked. Now this. Thank you guys for any help</p>
