PhantomJS-找不到变量：Intl

Question

我正在使用Phantomjs 2.1.1：

require('phantomjs-polyfill')
var server = require('webserver').create();
var fs = require('fs');
var port = 6000;

var service = server.listen(port, function (request, response) {
        var width = 1920;
        var height = 1080;

        page = require('webpage').create();
        system = require('system');   


        page.settings.clearMemoryCaches = true;
        page.clearMemoryCache();        
        //Screen resolution
        page.viewportSize = {width: width, height: height};
        //User agent
        page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36';
        page.settings.javascriptEnabled = true;
        page.settings.webSecurityEnabled = false;
        page.settings.localToRemoteUrlAccessEnabled = true;
        page.onConsoleMessage = function(msg) {
            system.stderr.writeLine('Console: ' + msg);
        };

        page.onClosing = function(closingPage) {
            CurrentStep = 1;
            ScreenShot("closing.png");
            console.log('URL: ' + page.url);
            console.log('The page is closing! URL: ' + closingPage.url);
        };


        page.open("http://test.com", function(status) {

            page.evaluate(function(w, h) {
                document.body.style.width = w + "px";
                document.body.style.height = h + "px";
            }, width, height);

            if (status === "success") {
                console.log("Page loaded");
            }
        });  

        page.evaluate(function() {
            var number = 123456.789;

            console.log(new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR' }).format(number));
            // expected output: "123.456,79 €"

            // the Japanese yen doesn't use a minor unit
            console.log(new Intl.NumberFormat('ja-JP', { style: 'currency', currency: 'JPY' }).format(number));
            // expected output: "￥123,457"

            // limit to three significant digits
            console.log(new Intl.NumberFormat('en-IN', { maximumSignificantDigits: 3 }).format(number));
        });
    }
});
console.log("Server started!");

但是，当我使用以下命令运行脚本时：

phantomjs --web-security=false ./test.js

我收到错误：

Console: ReferenceError: Can't find variable: Intl

我已经看到PhantomJs 2.1.1不支持polyfill，这就是为什么我安装了phantomjs-polyfill的原因，但是也许我没有将其正确添加到测试脚本中。

如何使这部分执行没有问题：

var number = 123456.789;

console.log(new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR' }).format(number));
// expected output: "123.456,79 €"

// the Japanese yen doesn't use a minor unit
console.log(new Intl.NumberFormat('ja-JP', { style: 'currency', currency: 'JPY' }).format(number));
// expected output: "￥123,457"

// limit to three significant digits
console.log(new Intl.NumberFormat('en-IN', { maximumSignificantDigits: 3 }).format(number));

以前有人遇到过这个问题吗？有可能解决吗？
