Unable to find expo in this project - have you run yarn / npm install yet?

Solution 1:

enter image description here

  1. Change expo version from "^1.0.0" to "~41.0.1" (package.json)
  2. npm install
  3. npm start

Solution 2:

I'm also facing this error. So I run the npm command in the terminal.

npm install

You do not need to change the expo version. you just reinstall it.
