Google maps Angular2 bundle.js:2未捕获引用错误：未定义google

我使用Angular的2.0.0-rc.4版本。我总是“谷歌未定义”问题出现在我的控制台上

我的**gulpfile.js**文件

  var gulp = require('gulp');

    gulp.task('bundle', function() {
        var SystemBuilder = require('systemjs-builder');
        var builder = new SystemBuilder();

        builder.loadConfig('./system.config.js')
            .then(function(){
                var outputFile = 'dist/bundle.js';
                return builder.buildStatic('app', outputFile, {
                    minify: true,
                    mangle: true,
                    rollup: true
                });
            })
            .then(function(){
                console.log('bundle built successfully!');
            });
    });
