Meteor - IE11 displays a blank page

Question

I get this error under IE11:

object doesn't support this property or method "for" on line:

var esSymKey = useSymbol ? Symbol.for(esStrKey) : null; 

from node_modules/meteor/modules/node_modules/reify/lib/runtime/utils.js
in modules.js.

I tried to update everything but with no luck

My packages list is as follow:

meteor-base

mobile-experience
mongo
blaze-html-templates 
session     
[email protected]  
tracker
es5-shim

coffeescript
msavin:mongol

Do you have any idea?

Thanks.

IE 11 doesn't support Symbol

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol

You will need to add a polyfill to add support for it.

If you're using other es6+ features, you will probably run into another error immediately after polyfilling Symbol. You should probably use some kind of transpiler, like Babel. It will ensure your new code works on old browsers.
