使用gulp-jspm从Gulp调用jspm缩小

Question

我正在做一个项目，它使用gulp调用jspm来缩小所有的javascript文件。

本应运行的Gulp任务是

    gulp.task('jspm_minify', function () {
       gulp.src('./app/spa/app.js')
         .pipe(gulp_jspm ())
         .pipe(gulp.dest('./wwwroot/js/'));
});

这会产生以下错误，

但是，如果我使用下面的普通命令行代码运行缩减，它就可以工作。

jspm bundle app/spa/app  wwwroot/js/spa.min.js --minify

我们的应用程序是一个SPA。使用angular JS。使用JSPM加载和管理模块。

有没有人遇到过这个问题？

谢谢。

我认为这只是一个斜杠的问题

在错误日志的第一行中：

C://\code\Dev-Stable\src\ProjectName.Web\app\spa\app.js

也许你可以使用gulp-slash或者自己修改路径。
