我对 gulp 和我的图像目录有一个奇怪的问题。我有一系列图像src/img，但是在运行 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，但文件名正确。
这以前工作得很好，最近无缘无故地变得很糟糕。
这是我的 gulpfile.js，改编自这篇博文：
// 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');
});
});
});
