"TypeError: exists is not a function"

See original GitHub issue

When ever I try to run a script I bundled with browserify it gives me the error:

Uncaught TypeError: exists is not a function
    at Function.getRoot (strobe_bundle.js:7582)
    at bindings (strobe_bundle.js:7484)

In console, can anyone help?

Here is my original unbundled code `var five = require(“johnny-five”), board = new five.Board();

board.on(“ready”, function() { // Create an Led on pin 13 var led = new five.Led(13);

// Strobe the pin on/off, defaults to 100ms phases led.strobe(); });`

I put it in a pastebin if that helps https://pastebin.com/bu1r8iFg Thanks

I’ve gotten this problem when trying to bundle an application of mine with browserify. However, I don’t use anything that refers to c++ bindings. If I recall correctly, leveldb is supposed to run in the browser. Must be missing something here.
