9# WHY WE NEED THIS:
10# This script is used to find a valid instance of `node` installed in the machine.
11# This script is sourced by other scripts to get access to node.
12# Specifically, it is used by the `react-native-xcode.sh` script, invoked by a
13# post-build phase in Xcode, to build the js files required by React Native.
14#
15# DEPRECATION NOTE:
16# React Native should not make assumptions on your current node environment.
17# This file is deprecated and will be removed in a future release in favor of something
18# node-agnostic and configurable by the developers.

20# remove global prefix if it's already set
21# the running shell process will choose a node binary and a global package directory breaks version managers
