古普夫对德尔不起作用

Question

使用此代码：

 global.release = argv.release;
    var gulp = require('gulp');
    var gulpif = require('gulp-if');
    var del = require('del');

    module.exports = gulp.task('clean', function (cb) {
        return gulpif(release, del([TMP_FOLDER, PHONEGAP_FOLDER],cb), del([TMP_FOLDER, BUILD_FOLDER],cb));
    });

我有个错误：

[14:07:35] Starting 'default'...

是虫子吗？如果不是，那是怎么回事？

两个问题：

• 你正在尝试使用乙烯基流之外的吞咽。
• 戴尔可不是个好朋友。

你不需要吞咽-如果你的例子是：

module.exports = gulp.task('clean', function(cb) {
  del(release ? [TMP_FOLDER, PHONEGAP_FOLDER] : [TMP_FOLDER, BUILD_FOLDER], cb);
});

三元吞咽插件:有条件地控制乙烯基物体的流动。
