无法让吞咽和吞咽图像正常工作

Question

半年来，我一直在使用这个gulpfile.js (如下所示)，它工作得天衣无缝。现在，在Windows8.1 64位上，我无法让它正常工作几个小时。我在火狐中使用LiveReload来查看RealTime中的更改，并使用Growl来获取更改的通知。

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']);

遵守ver3。吞咽(或吞咽-通知？)但它仍然没有解决这个问题。

我的问题是，目前我不能让脚本像以前一样工作，无法注意到图像中的变化，无法将文件压缩为.css文件，也无法注意到我是否放置了main.sass /js文件并相应地移动了它们。图像部分并不那么重要，但SASS却很重要。它应该相应地把它放在/编译/css或/编译/图像中。

每次我尝试更改和保存sass文件时，我都会得到这样的结果：

当然，我尝试更改路径，尝试在函数中直接使用路径，而不是传递变量，但都无济于事。有什么建议吗？我已经挣扎了4个小时，我确实设法让它在某种程度上工作，但我不得不删除许多功能，并重新启动每一次。我也不能让图像“缩小”。

Answer 1

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。我更改了gulp.tasks，只执行一件事。

因为我使用的是Windows8.1，所以我有操作系统通知，但我更喜欢使用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']);
