fs.realpath
Use node's fs.realpath, but fall back to the JS implementation if the native one fails
fs.realpath
A backwards-compatible fs.realpath for Node v6 and above
In Node v6, the JavaScript implementation of fs.realpath was replaced with a faster (but less resilient) native implementation. That raises new and platform-specific errors and cannot handle long or excessively symlink-looping paths.
This module handles those cases by detecting the new errors and falling back to the JavaScript implementation. On versions of Node prior to v6, it has no effect.
