# WHY WE NEED THIS:
|
|
|
# This script is used to find a valid instance of `node` installed in the machine.
|
|
|
# This script is sourced by other scripts to get access to node.
|
|
|
# Specifically, it is used by the `react-native-xcode.sh` script, invoked by a
|
|
|
# post-build phase in Xcode, to build the js files required by React Native.
|
|
|
#
|
|
|
# DEPRECATION NOTE:
|
|
|
# React Native should not make assumptions on your current node environment.
|
|
|
# This file is deprecated and will be removed in a future release in favor of something
|
|
|
# node-agnostic and configurable by the developers.
|
|
|
|
|
|
# remove global prefix if it's already set
|
|
|
# the running shell process will choose a node binary and a global package directory breaks version managers
