I was running into a React Native build issue where I was getting this (only captured part of the error message, unfortunately):

Target Support Files/yoga/yoga.xcconfig: unable to open file (in target "yoga" in project "Pods") (in target 'yoga' from project 'Pods')

To fix:

rm -rf ios/build

// Run `yarn add -D reactotron-react-native` first.

import React from 'react';
import {View, Text} from 'react-native';
import Reactotron from 'reactotron-react-native';

Reactotron.onCustomCommand({
  command: 'someCommand',
  handler: () => null,
});

Problem: I ran into a problem where running yarn would result in a weird fsevents error with a large backtrace.

Solution: Delete your yarn.lock file and yarn again.

yarn install v1.12.3
warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear this warning, remove package-lock.json.
