javascript - 在默认 gulp 任务中使用询问器

Question

我一直在重构现有网站，以更有效地使用 gulp 和 npm。我想将查询器合并到我的任务中来定义一些构建替代方案。现在我从简单开始。

这是我当前的 gulpfile:

//Define our required components
var gulp = require('gulp');
var inq = require('inquirer');
var plugins = require('gulp-load-plugins')({ scope: ['dependencies', 'devDependencies'] });

//Function that retrieves the file for the specifically names task
function getTask(task) {
    return require('./gulp-tasks/' + task)(gulp, plugins);
};

//Call for our tasks
gulp.task('thirdPartyComponents', getTask('ThirdPartyComponents'));
gulp.task('thirdPartyComponents.css', getTask('ThirdPartyComponentsCss'));
gulp.task('buyer.app', getTask('Buyer.App'));
gulp.task('buyer.controllers', getTask('Buyer.Controllers'));
gulp.task('buyer.directives', getTask('Buyer.Directives'));
gulp.task('buyer.filters', getTask('Buyer.Filters'));

//CODE NOTE: Dependent tasks are case-sensitive
gulp.task('default', function () {
    var questions =
        [
            {
                type: 'confirm',
                name: 'minimize',
                message: 'Do you want to minimize the files?',
                default: true
            }
        ];

    inq.prompt(questions).then(function (answers) {
        console.log(answers);
    });
});

当我运行任务时，我会在任务资源管理器的输出窗口中看到它

[16:21:21] Using gulpfile ....

我不确定为什么这么简单的事情不想启动......非常感谢任何帮助。

发现问题了，和代码没有直接关系。我在 Visual Studio 中运行，并使用任务运行程序资源管理器来调用默认任务。这就是我看到问题的地方。

在做了更多研究之后，我一时兴起，从命令窗口运行了 gulp 任务。它按预期完成。因此，使用 process.stdin 命令的任务运行程序中仍然存在问题。
