Javascript 返回流的吞咽任务会随着时间的推移而变慢

javascript gulp

Javascript 返回流的吞咽任务会随着时间的推移而变慢,javascript,gulp,Javascript,Gulp,我一直有一个奇怪的吞咽问题。首先，这是我的gulpfile： var gulp = require('gulp'), rename = require('gulp-rename'), plumber = require('gulp-plumber'), connect = require('gulp-connect'), watch = require('gulp-watch'), less = require('gulp-less'), less

我一直有一个奇怪的吞咽问题。首先，这是我的gulpfile：

var gulp = require('gulp'),
    rename = require('gulp-rename'),
    plumber = require('gulp-plumber'),
    connect = require('gulp-connect'),
    watch = require('gulp-watch'),
    less = require('gulp-less'),
    lessPluginAutoprefix = require('less-plugin-autoprefix'),
    minifyCSS = require('gulp-minify-css');

autoprefix = new lessPluginAutoprefix({browsers: ["> 0%"] });

gulp.task('webserver', function() {
    connect.server({
        port: 8000,
        livereload: true,
        root: ['src']
    });
});

gulp.task('livereload', function() {
    var watchedFiles = [
        'src/html/**/*.html',
        'src/style/**/*min.css',
        'src/javascript/**/*.js'
    ];
    gulp
        .src(watchedFiles)
        .pipe(watch(watchedFiles))
        .pipe(connect.reload());
});

gulp.task('less', function() {
    return gulp
        .src('src/style/less/main.less')
        .pipe(plumber(function(err) {
            console.log(err.toString());
            this.emit('end');
        }))
        .pipe(less({
            plugins: [autoprefix]
        }))
        .pipe(gulp.dest('src/style'));
});

gulp.task('minifyCSS', ['less'], function() {
    return gulp
        .src(['src/style/**/*.css', '!./src/style/**/*.min.*'])
        .pipe(minifyCSS({advanced: true}))
        .pipe(rename({suffix: '.min'}))
        .pipe(gulp.dest('src/style'));

});

gulp.task('watch', function() {
    gulp
        .watch('src/style/less/**/*.less', ['less', 'minifyCSS']);
});

gulp.task('default', ['less', 'minifyCSS', 'webserver', 'livereload', 'watch']);

如您所见，这是一个简单的项目，它设置了一个Web服务器，监视一些文件，并相应地执行较少的编译或重新加载Web服务器。除了返回流的任务（less和minifyCSS）随着时间的推移而变慢之外，所有任务都可以正常运行。下面让我显示修改某些监视文件后的执行时间：

而且速度越来越慢，修改任何文件都需要很长时间才能在浏览器中刷新，这可能是什么问题

致以最良好的祝愿。
我记得看到过类似的案例。尝试重写globs，这样就不会有否定了。@Heikki是的，我已经尝试完全删除minifyCSS任务，但问题仍然存在。
