Question

我正在学习gulp，并写下我的第一个任务。我完成了这个任务：

gulp.task('js-libs', function () {
    return gulp.src([
        // Add JavaScript Files here
        './node_modules/jquery/dist/jquery.min.js'
    ])
        // Output for Angular Files
        .pipe(gulp.dest('./dist/js/'))
        .on('error', js-libs.logError);
});

当我运行它时，我在终端中收到此错误：

$ gulp js-libs
[01:02:41] Using gulpfile ~\PhpstormProjects\xxx\gulpfile.js
[01:02:41] Starting 'js-libs'...
[01:02:41] 'js-libs' errored after 7.28 ms
[01:02:41] ReferenceError: js is not defined
    at Gulp.<anonymous> (C:\Users\xxx\PhpstormProjects\xxx\gulp\javascript.js:27:22)

    at Gulp.Orchestrator._runTask (C:\Users\xxx\PhpstormProjects\xxx\node_modules\gulp\node_modules\orchestrator\index.js:273:3)

    at process._tickCallback (node.js:349:13)
    at Function.Module.runMain (module.js:443:11)
    at startup (node.js:139:18)

所以现在是个大问题......出了什么问题？该脚本工作正确...它采取js文件并将它们放在我想要的地方。但为什么我收到此错误消息？

根据您发布的剪辑，错误消息显示行和确切的错误：

js-libs.logError

这是在寻找一个名为js的变量，并试图减去libs.logError。

Gulp Error - ReferenceError：未定义js
