我设置了一个 gulp 文件，并且我已经正确缩小了我的所有脚本和 css 文件，除了 mybundle.js和 my homeBundle.js. 我的uglify()每个任务都在运行该功能，但是当我尝试吞咽时收到以下错误。

events.js:141 抛出错误；// 未处理的“错误”事件 ^ 错误：/Users/Documents/RTVS360/bundle.js：不支持流式传输

当 gulp 尝试 uglify 时是否存在问题，因为它每次运行 gulp 时都会重新创建文件？

下面你可以看到我的 gulpfile。任何帮助将不胜感激。

var gulp = require('gulp');
var reactify = require('reactify');
var browserify = require('browserify');
var watchify = require('watchify');
var source = require('vinyl-source-stream');
var uglify = require('gulp-uglify');
var uglifycss = require('gulp-uglifycss');
var glob = require('glob');
var streamify = require('gulp-streamify');

gulp.task('watchify', function () {
    var bundler = browserify({
        entries: ['./client/main.jsx'],
        transform: [reactify],
        debug: true,
        cache: {},
        packageCache: {},
        fullPaths: true
    });

    var watcher = watchify(bundler);

    return watcher
        .on('update', function () {
            watcher.bundle()
                .on('error', function (err) {
                    console.log('There was an error compiling the components.', err.message);
                })
                .pipe(source('bundle.js'))
                .pipe(gulp.dest('./dest/'));
        })
        .bundle()
        .on('error', function (err) {
            console.log('There was an error compiling the components.', err.message);
        })
        .pipe(source('bundle.js'))
        .pipe(gulp.dest('./dest/'));
});

gulp.task('browserify', function () {
    var testFiles = glob.sync('./client/main.jsx');
    var bundler = browserify({
        entries: testFiles,
        transform: [reactify],
        debug: true,
        cache: {},
        packageCache: {},
        fullPaths: true
    });

    function rebundle() {
        bundler
        .bundle()
        .on('error', function(err) {
            console.log('There was an error compiling the components.', err.message);
        })
        .pipe(source('bundle.js'))
        .pipe(uglify())
        .pipe(gulp.dest('./dest/'));
    }
    return rebundle();
});

gulp.task('home', function () {

    var testFiles = glob.sync('./client/homepage.jsx');
    var bundler = browserify({
        entries: testFiles,
        transform: [reactify],
        debug: true,
        cache: {},
        packageCache: {},
        fullPaths: true
    });

    function rebundle() {
        bundler
        .bundle()
        .on('error', function(err) {
            console.log('There was an error compiling the components.', err.message);
        })
        .pipe(source('homeBundle.js'))
        .pipe(uglify())
        .pipe(gulp.dest('./dest/'));
    }

    return rebundle();
});


// Uglify Scripts
gulp.task('scripts', function() {
    gulp.src('assets/js/*.js')
    .pipe(uglify())
    .pipe(gulp.dest('dist/js'))
});

// Minify Styles
gulp.task('styles', function() {
  gulp.src('./assets/css/**/*.css')
    .pipe(uglifycss({
      "max-line-len": 80
    }))
    .pipe(gulp.dest('./dist/css'));
});


gulp.task('default', ['browserify', 'home','scripts', 'styles']);

您需要将 streamify 与 gulp-uglify 一起使用。

似乎您正在导入 streamify 插件，但您没有使用它。您应该使用 streamify 函数包装您的 uglify 调用。例子：

var gulp = require('gulp');
var reactify = require('reactify');
var browserify = require('browserify');
var watchify = require('watchify');
var source = require('vinyl-source-stream');
var uglify = require('gulp-uglify');
var streamify = require('gulp-streamify');

gulp.task('watchify', function () {
    var bundler = browserify({
        entries: ['main.jsx'],
        transform: [reactify],

        // You probably would like to change these two flags to false for
        // production since they increase the size of your output file
        debug: true,
        fullPaths: true,

        cache: {},
        packageCache: {}
    });

    var watcher = watchify(bundler);

    return watcher
        .on('update', function () {
            watcher.bundle()
                .on('error', function (err) {
                    console.log('There was an error compiling the components.', err.message);
                })
                .pipe(source('bundle.js'))
                .pipe(streamify(uglify()))
                .pipe(gulp.dest('./dest/'));
        })
        .bundle()
        .on('error', function (err) {
            console.log('There was an error compiling the components.', err.message);
        })
        .pipe(source('bundle.js'))
        .pipe(streamify(uglify())) // wrap uglify with the streamify plugin
        .pipe(gulp.dest('./dest/'));
});

gulp.task('default', ['watchify']);

Gulp-uglify 本身不支持流式传输乙烯基文件对象，因此您需要使用 streamify 插件使其支持流式传输。
