在我的Gulpfile中,我遇到一个问题,那就是控制台中总是会出现错误:
[22:33:32] The following tasks did not complete: default, watch, watch:views, watch:styles, watch:scripts
[22:33:32] Did you forget to signal async completion?
但是,据我所知,我只是定义了一些监视任务,对此没有任何怀疑。那么,gulp watch任务的错误在哪里?
gulp.task('reload', (done) => {
browserSync.reload();
done();
});
gulp.task('watch:views', () => {
gulp.watch(getPath(paths.views.watch), gulp.series('lint', gulp.parallel('views', 'assets'), 'reload'));
});
gulp.task('watch:styles', () => {
gulp.watch(getPath(paths.styles.all), gulp.series('lint', gulp.parallel('styles', 'assets'), 'reload'));
});
gulp.task('watch:scripts', () => {
gulp.watch(getPath(paths.scripts.all), gulp.series('scripts', 'reload'));
});
gulp.task('watch', gulp.parallel('watch:views', 'watch:styles', 'watch:scripts'));
gulp.task('default', gulp.series(
'clean',
'lint',
gulp.parallel(['views', 'styles', 'scripts', 'assets']),
'serve',
'watch',
));
已更新:资产,样式和脚本任务。
这些任务被定义为其他文件中的导出默认功能。在gulpfile中,它们将被加载并设置为任务。单独调用这些任务没有问题,它们将正确完成异步完成的信号。并且默认任务(包括所有这些任务)运行良好。只是当监视任务开始时它就会失败。
