javascript - Autoprefixer在Gulpfile.js中不起作用

伙计们，我在gulp文件中添加了Autoprefixer插件，一切正常，但CSS不会吐出自动前缀的CSS。我很乐意获得帮助。以下是我的gulpfile.js：

// require gulp
var gulp = require('gulp');

// require other packages
var concat = require('gulp-concat'),
    cssmin = require('gulp-minify-css'),
    rename = require("gulp-rename"),
    sass = require('gulp-sass'),
    browserSync = require('browser-sync'),
    uglify = require('gulp-uglify'),
    changed = require('gulp-changed'),
    imagemin = require('gulp-imagemin'),
    autoprefix = require('gulp-autoprefixer');

// scripts task
gulp.task('scripts', function() {
  return gulp.src('./src/js/*.js')
    .pipe(concat('app.js'))
    .pipe(gulp.dest('./dist/js/'))
    .pipe(uglify())
    .pipe(rename({
      suffix: '.min'
    }))
    .pipe(gulp.dest('./dist/js/'));
});

// styles task
gulp.task('styles', function() {
  return gulp.src('./src/sass/*.scss')
    .pipe(autoprefix('last 2 versions'))
    .pipe(sass())
    .pipe(gulp.dest('./dist/css/'))
    .pipe(cssmin())
    .pipe(rename({
      suffix: '.min'
    }))
    .pipe(gulp.dest('./dist/css/'));
});

// browser sync
gulp.task('browser-sync', ['styles'], function() {
    browserSync({
        server: {
            baseDir: ''
        },
        notify: false
    });
    gulp.watch("./src/sass/*.scss", ['scss']);
    gulp.watch("*.html").on('change', browserSync.reload);
});

// watch task
gulp.task('watch', function() {
  gulp.watch('./src/js/*.js', ['scripts']);
  gulp.watch('./src/sass/*.scss', ['styles']);
});

// image minification
gulp.task('imagemin', function() {
  var imgSrc = './src/img/**/*',
      imgDst = './dist/img';

  gulp.src(imgSrc)
    .pipe(changed(imgDst))
    .pipe(imagemin())
    .pipe(gulp.dest(imgDst));
});

gulp.task('default', ['scripts', 'styles', 'browser-sync', 'imagemin', 'watch']);

我希望你们能通过这个帮助我:)

最佳答案

传递给config的autoprefixer是错误的。它应该是

.pipe(autoprefix({
        browsers: ['last 2 versions']
    }))

参考：gulp-autoprefixer
