Question

我有一个包含各种任务的gulp文件。第一个任务创建一个sass文件，后面的任务是使用该文件。如果我明确地运行了两个任务（gulp sass，确保创建了sass文件然后运行gulp template-cache）它们就可以正常运行。

但是，当运行gulp任务连接这些任务时，任务失败，因为尚未创建文件template-cache所需，即使sass任务已声明已完成。这是两个任务：

gulp.task('sass', function(){
    sass(PATH.APP + '/**/*.scss', {sourcemap: true, style: 'expanded', compass: true})
    .pipe(autoprefixer({browsers:['last 4 versions']}))
    .pipe(sourcemaps.write())
    .on('error', sass.logError)
    .pipe(gulp.dest(PATH.APP))
    .pipe(livereload());
});

gulp.task('template-cache', function () {
    return gulp.src(PATH.APP + '/*/**/*.html')
    .pipe(templateCache({ filename:'templates.js', module:'app' }))
    .pipe(gulp.dest(PATH.DIST + '/scripts'));
});

这是执行构建的gulp任务：

gulp.task('default', sequence(
    ['sass', 'replace-config-local'],
    'build',
    'icons',
    'revision'
    ,'uglify'
));

这是构建任务：

gulp.task('build', sequence('clean', ['useref', 'template-cache'], 'concat', 'delete-templates'));

我得到的错误信息是：

Answer 1

正如@MadScone在评论中所建议的，返回流解决了问题。例如，将gulp.src(PATH.DIST + '/**')更改为return gulp.src(PATH.DIST + '/**')。

Gulp任务失败，因为先前的任务没有创建所需的文件
