半年过去了，我一直在使用这个 gulpfile.js（如下所示），它运行良好。现在，在 Windows 8.1 64bit 上，我无法让它从几个小时内正常工作。我在 Firefox 中使用 LiveReload 来查看 RealTime 和 Growl 中的更改以获取它已更改的通知。

整个源代码是：

var gulp = require('gulp'),
    gutil = require('gulp-util'),
    notify = require('gulp-notify'),
    autoprefix = require('gulp-autoprefixer'),
    minifyCSS = require('gulp-minify-css'),
    exec = require('child_process').exec,
    sys = require('sys'),
    uglify = require('gulp-uglify'),
    changed = require('gulp-changed'),
    livereload = require('gulp-livereload'),
    rename = require('gulp-rename'),
    imagemin = require('gulp-imagemin'),
    cache = require('gulp-cache'),
    path = require('path'),
    watch = require('gulp-watch'),
    sass = require('gulp-sass');

// Which directory should Sass compile to?
var targetDir = 'resources/compiled';

      //  .pipe(minifyCSS())
gulp.task('scss', function () {
    gulp.src('resources/uncompiled/**/*.scss')
        .pipe(changed(targetDir))
        .pipe(sass({errLogToConsole: true}))
        .pipe(autoprefix('last 15 version'))
        .pipe(changed(targetDir))
  .on('error', gutil.log)
        .pipe(gulp.dest(targetDir));

    //! .sass files -> compile, minify, autoprefix and publish
    watch('resources/uncompiled/**/*.scss', function(files) {
        return files.pipe(changed(targetDir))
            .pipe(sass({errLogToConsole: true}))
            .pipe(autoprefix('last 15 version'))
   .on('error', gutil.log)
            .pipe(gulp.dest(targetDir))
            .pipe(notify({
                message: "File: <%= file.relative %>",
                title: "SASS compiled, minified and published."
            }));
    });

});

gulp.task('js', function() {
    gulp.src('resources/uncompiled/**/*.js')
        .pipe(changed(targetDir))
        .pipe(uglify())
        .pipe(changed(targetDir))
        .pipe(gulp.dest(targetDir))
        .pipe(notify({
            message: "File: <%= file.relative %>",
            title: "JavaScript minified and published."
        }));

    //! .js files -> compress and publish
    watch('resources/uncompiled/**/*.js', function(files) {
        return files.pipe(changed(targetDir))
            .pipe(uglify())
            .pipe(rename(function(path) {
                path.dirname = path.dirname.replace(/assets\//g, "");
            }))
            .pipe(changed(targetDir))
            .pipe(gulp.dest(targetDir))
            .pipe(notify({
                message: "File: <%= file.relative %>",
                title: "JavaScript minified and published."
            }));
    });
});

gulp.task('images', function() {
    gulp.src(['resources/uncompiled/**/*.png', 'resources/uncompiled/**/*.jpg', 'resources/uncompiled/**/*.ico', 'resources/uncompiled/**/*.gif'])
        .pipe(changed(targetDir))
        .pipe(cache(imagemin({ optimizationLevel: 5, progressive: true, interlaced: true })))
        .pipe(changed(targetDir))
        .pipe(gulp.dest(targetDir));

    //! image files -> compress and publish
    watch(['resources/uncompiled/**/*.png', 'resources/uncompiled/**/*.jpg', 'resources/uncompiled/**/*.ico', 'resources/uncompiled/**/*.gif'], function(files) {
        return files.pipe(changed(targetDir))
            .pipe(cache(imagemin({ optimizationLevel: 5, progressive: true, interlaced: true })))
            .pipe(rename(function(path) {
                path.dirname = path.dirname.replace(/assets\//g, "");
            }))
            .pipe(changed(targetDir))
            .pipe(gulp.dest(targetDir))
            .pipe(notify({
                message: "Image: <%= file.relative %>",
                title: "Image optimized and published."
            }));
    });
});


gulp.task('watch', function () {

    // Create LiveReload server
    var server = livereload();

    // Watch any files in public dir, reload on change
    gulp.watch(['resources/compiled/**']).on('change', function(file) {
        server.changed(file.path);
    });
});

// What tasks does running gulp trigger?
gulp.task('default', ['scss', 'js','images', 'watch']);

现在，我注意到我需要更改这些行

    gulp.watch(['resources/compiled/**']).on('change', function(file) {
        server.changed(file.path);
    });

至

 livereload.listen();
 gulp.watch('resources/uncompiled/**/*.scss', ['scss']);

符合ver3。吞咽（或吞咽通知？），但它仍然没有解决它。

我的问题是，目前我无法让脚本像以前一样工作，注意到 main.sass 中的更改并将该文件压缩为 .css 文件，并且还注意到我是否放置了图像/js 文件并移动它们因此。图片部分并不那么重要，但 SASS 才是。它应该相应地把它放在 /compiled/css 或 /compiled/images 中。

每次我尝试更改和保存 sass 文件时，都会得到以下信息：

当然，我尝试更改路径，尝试直接在函数中使用路径而不是传递变量，但无济于事。有什么建议么？我现在已经挣扎了 4 个小时，我确实设法让它在某种程度上工作，但我不得不删除很多功能并每次都重新启动 gulp。我也无法让图像“缩小”。

好吧，几天后，我自己解决了我的问题。

首先，我必须为每种类型设置一个 gulp.watch。我将 gulp.tasks 更改为只执行一件事。

现在每个 .scss sass、.js javascript、.jpg/.png/.bmp 图像文件都会被检查更改，如果是，则调用所需的任务，然后由它自己编译/缩小/移动受尊重的文件并触发（咆哮）通知。

由于我在 Windows 8.1 上，我确实有操作系统通知，但我宁愿使用 Growl，因此使用了 growlNotifications。

我的 gulpfile.js 的完整源代码：

var gulp = require('gulp'),
    gutil = require('gulp-util'),
    notify = require('gulp-notify'),
    autoprefix = require('gulp-autoprefixer'),
    minifyCSS = require('gulp-minify-css'),
    exec = require('child_process').exec,
    sys = require('sys'),
    uglify = require('gulp-uglify'),
    changed = require('gulp-changed'),
    livereload = require('gulp-livereload'),
    rename = require('gulp-rename'),
    imagemin = require('gulp-imagemin'),
    cache = require('gulp-cache'),
    path = require('path'),
    watch = require('gulp-watch'),
    growl = require('gulp-notify-growl'),
    sass = require('gulp-sass');

// Initialize the Growl notifier  instead of the default OS notifications
// meaning, this: https://i.imgur.com/ikkINZr.png 
// changes to this: https://i.imgur.com/zz9m9k6.png
var growlNotifier = growl({
    hostname : 'localhost' // IP or Hostname to notify, default to localhost 
});

// Which directory should the files compile to?
var targetDir = 'resources/compiled';

gulp.task('scss', function () {

    gulp.src('resources/uncompiled/**/*.scss')
        .pipe(changed(targetDir))
        //.pipe(minifyCSS())  //makes it hard to debug , to be used for in-production only
        .pipe(sass({errLogToConsole: true}))
        .pipe(autoprefix('last 15 version'))
        .pipe(changed(targetDir))
    .on('error', gutil.log)
        .pipe(gulp.dest(targetDir))        
        .pipe(growlNotifier({    // change to notify if you wish to use your default OS notifications
                message: "File: <%= file.relative %>",
                title: "SASS compiled, minified and published."
            }))
        .pipe(livereload());    //this is how we notify LiveReload for changes
});

gulp.task('js', function() {

    //needs testing, but it should be OK
    gulp.src('resources/uncompiled/**/*.js')
        .pipe(changed(targetDir))
        .pipe(uglify())
        .pipe(changed(targetDir))
    .on('error', gutil.log)
        .pipe(gulp.dest(targetDir))
        .pipe(notify({
                message: "File: <%= file.relative %>",
                title: "Javascript minified and published."
            }))
        .pipe(livereload());

});

gulp.task('images', function() {

    gulp.src(['resources/uncompiled/**/*.png', 'resources/uncompiled/**/*.jpg', 'resources/uncompiled/**/*.ico', 'resources/uncompiled/**/*.gif'])
        .pipe(changed(targetDir))
        //imagemin causes errors for me: http://pastebin.com/eDF3SeS6
        //.pipe(cache(imagemin({ optimizationLevel: 5, progressive: true, interlaced: true })))
        .pipe(changed(targetDir))
    .on('error', gutil.log)
        .pipe(gulp.dest(targetDir))
        .pipe(growlNotifier({
            message: "Image: <%= file.relative %>",
            title: "Image optimized and published."
        }))
        .pipe(livereload());

});

gulp.task('watch', function() {

    livereload.listen(); //we need to tell gulp to listen for livereload notification
    //this is how we watch for changes in specific files and fire specific tasks
    gulp.watch('resources/uncompiled/**/*.scss', ['scss']); 
    gulp.watch('resources/uncompiled/**/*.js', ['js']); 
    gulp.watch(['resources/uncompiled/**/*.png', 'resources/uncompiled/**/*.jpg', 'resources/uncompiled/**/*.ico', 'resources/uncompiled/**/*.gif'], ['images']); 

});

// What tasks does running gulp trigger?
gulp.task('default', ['scss', 'js','images', 'watch']);
