问题描述

当我使用gulp-uglify和browserify时，我得到一个错误

  events.js：72 
 throw er ; //未处理'错误'事件

这是我的脚本任务

  gulp.task（'scripts'，function（）{
 
 var bundler = browserify（{ b $ b条目：['./src/scripts/main.js']，
 debug：debug 
}）。transform（stringify（））; //即使没有这种转换，错误仍然存​​在
 
 bundler 
 .bundle（）
 .on（'error'，handleErrors）
 .pipe（source（getBundleName（ ）+'.js'））
 .pipe（jshint（））
 .pipe（jshint.reporter（'default'，{verbose：true}））
 .pipe（jshint。记者（'失败'））
 .pipe（buffer（））
 .pipe（sourcemaps.init（{loadMaps：true}））
 .pipe（uglify（））
 .pipe（sourcemaps.write（'./'））
 .pipe（gulp.dest（'./ web / js'））; 
}）; 
  

解决方案

我遇到了同样的问题， > gulp-concat-sourcemap 和 gulp-uglify 。我用 gulp-ignore 忽略地图文件解决了这个问题：

  gulp.task（uglify-src，function（）{
 gulp.src（[src / js / ** / *。js ]）
 .pipe（concat（app.js））
 .pipe（ignore.exclude（[** / *。map]））
 .pipe（uglify（ ））
 .pipe（gulp.dest（dist / js））; 
}）; 
  

When i use gulp-uglify with browserify i get a error

events.js:72
        throw er; // Unhandled 'error' event
              ^

    at expression (/home/rkmax/my-project/node_modules/gulp-uglify/node_modules/uglify-js/lib/parse.js:1410:20)

this is my scripts task

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

    var bundler = browserify({
        entries: ['./src/scripts/main.js'],
        debug: debug
    }).transform(stringify()); // the error persist even without this transformation

    bundler
        .bundle()
        .on('error', handleErrors)
        .pipe(source(getBundleName() + '.js'))
        .pipe(jshint())
        .pipe(jshint.reporter('default', { verbose: true }))
        .pipe(jshint.reporter('fail'))
        .pipe(buffer())
        .pipe(sourcemaps.init({loadMaps: true}))
        .pipe(uglify())
        .pipe(sourcemaps.write('./'))
        .pipe(gulp.dest('./web/js'));
});

解决方案

I encountered this same issue with gulp-concat-sourcemap and gulp-uglify. I solved it by ignoring map files with gulp-ignore:

gulp.task("uglify-src", function() {
    gulp.src([ "src/js/**/*.js" ])
    .pipe(concat("app.js"))
    .pipe(ignore.exclude([ "**/*.map" ]))
    .pipe(uglify())
    .pipe(gulp.dest("dist/js"));
});
