Essentially, the error seems to come down to this…
/node_modules/expo/AppEntry.js: Cannot find module ‘babel-plugin-transform-react-jsx-source’
Causing a 500 server response.
After following the upgrade instructions in the expo article on medium, I ran
yarn and got the following warnings and a detox related error which may be relevant, especially since it exited…but I’m not sure how to resolve nor am I sure how/why the detox postinstall script is being run.
I’ve tried wiping out the node_modules directory and stepping through the upgrade steps a couple times, but always with the same result.
