NPM Run Build issue on MAC

[kondrusiva3]

Hi Team,

Here is the error log that am getting while trying to build the app, i have seen few recommendation to use "%" in the build path $SPLUNK_HOME/bin/splunk cmd node ./node_modules/webpack/bin/webpack.js, but i think thats a fix for Windows machine, could you please gimme a solution the path setting on MAC.
