Question

gulp和我的images目录有一个奇怪的问题。我在src/img中有一系列图像，但在运行gulp之后，输出文件夹dist/img中的每个图像都是源目录中最后一个图像的精确副本，但具有正确的文件名。

这之前工作正常，最近因为没有明显原因而变得很糟糕。

这是我的gulpfile.js，改编自this blog post：

// Load plugins
var gulp = require('gulp'),
    sass = require('gulp-ruby-sass'),
    autoprefixer = require('gulp-autoprefixer'),
    minifycss = require('gulp-minify-css'),
    jshint = require('gulp-jshint'),
    uglify = require('gulp-uglify'),
    imagemin = require('gulp-imagemin'),
    rename = require('gulp-rename'),
    clean = require('gulp-clean'),
    concat = require('gulp-concat'),
    notify = require('gulp-notify'),
    cache = require('gulp-cache'),
    livereload = require('gulp-livereload'),
    lr = require('tiny-lr'),
    server = lr();

// Styles
gulp.task('styles', function() {
  return gulp.src('src/css/main.sass')
    .pipe(sass({ style: 'expanded', }))
    .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1', 'ios 6', 'android 4'))
    .pipe(gulp.dest('dist/css'))
    .pipe(rename({ suffix: '.min' }))
    .pipe(minifycss())
    .pipe(livereload(server))
    .pipe(gulp.dest('dist/css'))
    .pipe(notify({ message: 'Styles task complete' }));
});

// .pipe(jshint('.jshintrc'))
// .pipe(jshint.reporter('default'))

// Scripts
gulp.task('scripts', function() {
  return gulp.src('src/js/**/*.js')
    .pipe(concat('main.js'))
    .pipe(gulp.dest('dist/js'))
    .pipe(rename({ suffix: '.min' }))
    .pipe(uglify())
    .pipe(livereload(server))
    .pipe(gulp.dest('dist/js'))
    .pipe(notify({ message: 'Scripts task complete' }));
});

// Images
gulp.task('images', function() {
  return gulp.src('src/img/**/*')
    .pipe(cache(imagemin({ optimizationLevel: 3, progressive: true, interlaced: true })))
    .pipe(livereload(server))
    .pipe(gulp.dest('dist/img'))
    .pipe(notify({ message: 'Images task complete' }));
});

// Clean
gulp.task('clean', function() {
  return gulp.src(['dist'], {read: false})
    .pipe(clean());
});

// Default task
gulp.task('default', ['clean'], function() {
    gulp.run('styles', 'scripts', 'images');
});

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

  // Listen on port 35729
  server.listen(35729, function (err) {
    if (err) {
      return console.log(err)
    };

    // Watch .sass files
    gulp.watch('src/css/**/*.sass', function(event) {
      console.log('File ' + event.path + ' was ' + event.type + ', running tasks...');
      gulp.run('styles');
    });

    // Watch .js files
    gulp.watch('src/js/**/*.js', function(event) {
      console.log('File ' + event.path + ' was ' + event.type + ', running tasks...');
      gulp.run('scripts');
    });

    // Watch image files
    gulp.watch('src/img/**/*', function(event) {
      console.log('File ' + event.path + ' was ' + event.type + ', running tasks...');
      gulp.run('images');
    });

  });

});

我的猜测是它是gulp-cache插件。从图像任务中删除它。

缓存插件的更好替代品（在我看来，它有太多“魔力”）是gulp-newer插件，它根据文件的最后修改日期简单地过滤文件列表。它更简单，也不那么神奇。
