Could not fix this issue until updated dependency:

-    "rn-nodeify": "github:mvayngrib/rn-nodeify"
+    "rn-nodeify": "github:tradle/rn-nodeify"

I had the same issue since today. It was caused by package browserify/resolve, which introduced invalid package.json in its tests:

"main": [
  "why is this a thing",
  "srsly omg wtf"
]

This package.json is parsed by rn-nodeify and results in this error. As a workaround you may force version 1.8.1 of resolve in package.json of your project.

@shardick @Vanclief put it in dependencies in your package.json, but be sure to point to exact version (“compatible” may allow 1.9.0).

Looking through package-lock.json, it would seem that resolve is required by @babel/core which in turn is required by metro, React Native packager.

@nyl9488 maybe you put it in a wrong place. It should be in the dependencies section and with “1.8.1” exactly. And check what version in your package-lock.json. If you’ll see 1.9.0 - that’s bad. Try reinstall with: npm install --save resolve@1.8.1

Also, there’s already a fix for this issue, I hope @mvayngrib will publish this package soon so we can use it without forcing version.

I’ve added a check if main isn’t a string for such cases.
