gulp watch vesrion 4.0

Question

我想在我的项目中使用gulp-watch。 gulp-watch在我的gulpfile.js中不起作用。我在项目“ gulp”：“ ^ 4.0.0”中使用了gulp vesrion 4.0。我想在刷新页面时查看js文件中的更改。所以我用口水表，请帮帮我...谢谢

这是我在gulpfile.js中的代码

gulp.task("MainProjectLibrary", function () {
    return gulp.src([
        "./Public/DragDrop.js",
        "app.js",
        "./Constants/Errors.js",

        "./Modules/Dashboard/Controllers/DashboardController.js",
        "./Modules/Dashboard/Controllers/DepositController.js",

        "./Modules/Dashboard/Services/ChangeBrokerService.js",
        "./Modules/Dashboard/Services/DashboardService.js",
        "./Modules/Dashboard/Services/DepositService.js",
        "./Modules/Dashboard/Services/PaymentRequestService.js",
        "./Modules/Public/Services/SymbolMessageService.js",
        "./Modules/Reports/Controllers/AccountTransactionController.js"
    ])
        .pipe(concat("MainProjectLibrary.min.js"))
        .pipe(uglify())
        .pipe(gulp.dest("./Dist/"));
});

gulp.task("default", function() {
    return gulp.watch("./Dist/*.min.js", gulp.series("MainProjectLibrary"));
});

这是默认运行任务后的终端。任务未完成

仅通过将gulp的版本从4x更改为3x即可轻松解决先前的问题。
