gulpfile.babel.js - 使用sass而不是postcss

Question

我一般都是反应和专业工作流程的noobie，我正在尝试用下面的gulpfile.babel.js文件中的gulp-ruby-sass和gulp-autoprefixer替换postcss：

我已经安装了gulp-ruby-sass和gulp-autoprefixer，并从各自的模块中导入了sass和autoprefixer，但没有运气。

对于我需要做些什么才能让它发挥作用？

原创'postcss'gulpfile.babel.js：

import gulp from 'gulp';
import autoprefixer from 'autoprefixer';
import browserify from 'browserify';
import watchify from 'watchify';
import source from 'vinyl-source-stream';
import buffer from 'vinyl-buffer';

import babelify from 'babelify';
import uglify from 'gulp-uglify';
import rimraf from 'rimraf';
import notify from 'gulp-notify';
import browserSync, { reload } from 'browser-sync';
import sourcemaps from 'gulp-sourcemaps';
import postcss from 'gulp-postcss';
import atImport from 'postcss-import';
import rename from 'gulp-rename';
import nested from 'postcss-nested';

const paths = {

  srcLint: ['src/**/*.js', 'test/**/*.js'],
  dist: 'dist',
  distJs: 'dist/js',
  distImg: 'dist/images',
  distDeploy: './dist/**/*'
};

const customOpts = {
  entries: [paths.entry],
  debug: true,
  cache: {},
  packageCache: {}
};

const opts = Object.assign({}, watchify.args, customOpts);

gulp.task('clean', cb => {
  rimraf('dist', cb);
});

gulp.task('browserSync', () => {
  browserSync({
    server: {
      baseDir: './'
    }
  });
});

gulp.task('watchify', () => {
  const bundler = watchify(browserify(opts));

  function rebundle() {
    return bundler.bundle()
      .on('error', notify.onError())
      .pipe(source(paths.bundle))
      .pipe(buffer())
      .pipe(sourcemaps.init({ loadMaps: true }))
      .pipe(sourcemaps.write('.'))
      .pipe(gulp.dest(paths.distJs))
      .pipe(reload({ stream: true }));
  }

  bundler.transform(babelify)
  .on('update', rebundle);
  return rebundle();
});

gulp.task('browserify', () => {
  browserify(paths.entry, { debug: true })
  .transform(babelify)
  .bundle()
  .pipe(source(paths.bundle))
  .pipe(buffer())
  .pipe(sourcemaps.init({ loadMaps: true }))
  .pipe(uglify())
  .pipe(sourcemaps.write('.'))
  .pipe(gulp.dest(paths.distJs));
});

gulp.task('styles', () => {
  gulp.src(paths.srcCss)
  .pipe(rename({ extname: '.css' }))
  .pipe(sourcemaps.init())
  .pipe(postcss([atImport, vars, extend, nested, autoprefixer, cssnano]))
  .pipe(sourcemaps.write('.'))
  .pipe(gulp.dest(paths.dist))
  .pipe(reload({ stream: true }));
});

gulp.task('htmlReplace', () => {
  gulp.src('index.html')
  .pipe(htmlReplace({ css: 'styles/main.css', js: 'js/app.js' }))
  .pipe(gulp.dest(paths.dist));
});

gulp.task('images', () => {
  gulp.src(paths.srcImg)
    .pipe(imagemin({
      progressive: true,
      svgoPlugins: [{ removeViewBox: false }],
      use: [pngquant()]
    }))
    .pipe(gulp.dest(paths.distImg));
});

gulp.task('lint', () => {
  gulp.src(paths.srcLint)
  .pipe(eslint())
  .pipe(eslint.format());
});

gulp.task('watchTask', () => {
  gulp.watch(paths.srcCss, ['styles']);
  gulp.watch(paths.srcLint, ['lint']);
});

gulp.task('deploy', () => {
  gulp.src(paths.distDeploy)
    .pipe(ghPages());
});

gulp.task('watch', cb => {
  runSequence('clean', ['browserSync', 'watchTask', 'watchify', 'styles', 'lint', 'images'], cb);
});

gulp.task('build', cb => {
  process.env.NODE_ENV = 'production';
  runSequence('clean', ['browserify', 'styles', 'htmlReplace', 'images'], cb);
});

Answer 1

一些事情：

• autoprefixer()属于自己的.pipe()。它不应该像sass()那样传递给postcss()。
• gulp-ruby-sass无法在.pipe()中使用。请改用gulp-sass。
• sourcemaps.init()和sourcemaps.write()需要附上您的其他转化，否则您最终会得到一张空的源地图

以下内容应该有效：

import sass from 'gulp-sass';

gulp.task('sass', () => {
  return gulp.src(paths.srcCss)
   .pipe(sourcemaps.init())
   .pipe(sass().on('error', sass.logError))
   .pipe(autoprefixer())
   .pipe(sourcemaps.write('.'))
   .pipe(gulp.dest(paths.dist))
   .pipe(reload({ stream: true }));
});
