Getting this mysterious error from browserify on CircleCI - never seen this locally..

http://stackoverflow.com/questions/21685044/browserify-uncaught-error-cannot-find-module-in-bundle-js says this occurs when using a jison parser, sure enough https://github.com/rom1504/node-mojangson uses jison, but only as a dev dependency? Maybe its something else. The stackoverflow user says they fixed it in their case by "replacing that mindfuck exports part with a exports.parser = parser;"

if (typeof require !== 'undefined' && typeof exports !== 'undefined') {
    exports.parser = parser;
    exports.Parser = parser.Parser;
    exports.parse = function () {
        return parser.parse.apply(parser, arguments);
    };
    exports.main = function commonjsMain(args){
        if(!args[1]){
            console.log("Usage: "+args[0]+" FILE");
            process.exit(1)
        }
        var source=require("fs").readFileSync(require("path").normalize(args[1]),"utf8");
        return exports.parser.parse(source)
    };
    if (typeof module !== 'undefined' && require.main === module) {
        exports.main(process.argv.slice(1));
    }
}

and its using https://github.com/deathcap/jison/commits/modulemain which has https://github.com/deathcap/jison/commit/83a38136e958c32de16630099946ebe0357ea605.. for https://github.com/rom1504/node-mojangson/pull/4 Disable unused moduleMain code for browserify compatibility

There are differences in npm ls on voxel-clientmc/app, on my local system and circleci: https://gist.github.com/deathcap/1e530528e8fb3ae0d67b - mainly minor/patch version bumps

[rom1504]

@deathcap I think I found your problem, the published grammar.js seems to still contain the cli thingy. republishing it in a bit.

[deathcap]

@rom1504 cool thanks. reproduced locally was about to track it down =)

[rom1504]

fixed in mojangson 0.2.3 just rerun circle ci (possibly without cache, not sure how it handle npm cache) and that should do it.

[deathcap]

Updated and verified circleci is using mojangson 0.2.3 which has the main stub as expected:

exports.main = function (){};

so I think the problem with mojagson is fixed. Still getting this error though - maybe another problematic unbrowserifiable module:
