Spiderable.js exception on docker

[davinderkumar]

As this extension has dependency on spiderable package, which is causing the following error when I am deploying the application to Docker.
How can I remove the dependency because I want to you ongoworks:spiderable package instead of default one as ongoworks works fine in docker.

spiderable: phantomjs failed: null
stderr:
spiderable: phantomjs failed at http://www.myaddresspin.com/robots.txt: { [Error: Command failed: /usr/bin/env bash -c exec phantomjs --load-images=no --ssl-protocol=TLSv1 /dev/stdin <<'END'
var url = "http://www.myaddresspin.com/robots.txt";// 'url' is assigned to in a statement before this.
var page = require('webpage').create();

var isReady = function () {
return page.evaluate(function () {
if (typeof Meteor === 'undefined'
|| Meteor.status === undefined
|| !Meteor.status().connected) {
return false;
}
if (typeof Package === 'undefined'
|| Package.spiderable === undefined
|| Package.spiderable.Spiderable === undefined) {
return false;
}
return Package.spiderable.Spiderable.isReady();
});
};

var dumpPageContent = function () {
var out = page.content;
out = out.replace(/<script[^>]+>(.|\n|\r)?</script\s>/ig, '');
out = out.replace('', '');
console.log(out);
};

page.open(url, function(status) {
if (status === 'fail')
phantom.exit();
});

setInterval(function() {
if (isReady()) {
dumpPageContent();
phantom.exit();
}
}, 100);
END
