c# - ASP.NET MVC 4 Script bundling causes errors upon deployment

Question

My website is working fine on localhost when @Scripts.Render() is not bundling the scripts however when I deploy to my server the bundled Javascript must contain an error as all Javascript on my page stops working.

Here is my bundle code:

        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js",
                    "~/Scripts/jquery-migrate-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.unobtrusive*",
                    "~/Scripts/jquery.validate*"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                        "~/Scripts/jquery-ui-{version}.js",
                        "~/Scripts/jquery-ui.unobtrusive-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

            bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(
                        "~/Content/themes/base/jquery.ui.core.css",
                        "~/Content/themes/base/jquery.ui.resizable.css",
                        "~/Content/themes/base/jquery.ui.selectable.css",
                        "~/Content/themes/base/jquery.ui.accordion.css",
                        "~/Content/themes/base/jquery.ui.autocomplete.css",
                        "~/Content/themes/base/jquery.ui.button.css",
                        "~/Content/themes/base/jquery.ui.dialog.css",
                        "~/Content/themes/base/jquery.ui.slider.css",
                        "~/Content/themes/base/jquery.ui.tabs.css",
                        "~/Content/themes/base/jquery.ui.datepicker.css",
                        "~/Content/themes/base/jquery.ui.progressbar.css",
                        "~/Content/themes/base/jquery.ui.theme.css"));
        }

Here is my rendering code:

@Styles.Render("~/Content/css")
@Styles.Render("~/Content/themes/base/css")
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryval")
@Scripts.Render("~/bundles/jqueryui")
@Scripts.Render("~/bundles/modernizr")

Can someone explain what might be happening to my Javascript upon deployment?

Thanks, Alex.

You can also change your "new ScriptBundle" to just "new Bundle":

bundles.Add(new Bundle("~/bundles/modernizr").Include("~/Scripts/modernizr-*"));

This will bundle your assets without minification. I have run into some cases where minifying just wouldn't work with certain libraries, so this will still allow you to include them in your bundle.
