我设置了一个gulp文件,并且除我的bundle.js和homeBundle.js之外,我已经适当缩小了所有脚本和CSS文件.我在每个任务中都运行了uglify()函数,但是当我尝试吞咽时会收到以下错误.
events.js:141
throw er; // Unhandled ‘error’ event
^ Error: /Users/Documents/RTVS360/bundle.js: Streaming not supported
当gulp每次运行时都会重新创建文件时,gulp尝试进行丑化时是否存在问题?
在下面您可以看到我的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({

// 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({

}))
.pipe(gulp.dest('./dist/css'));
});
gulp.task('default', ['browserify', 'home','scripts', 'styles']);
解决方法:
您需要将streamify与gulp-uglify一起使用.
似乎您正在导入streamify插件,但未使用它.
您应该使用streamify函数包装uglify调用.例:
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本身不支持流式处理乙烯基文件对象,因此您需要使用streamify插件使其支持流.
