gulp-include和gulp-uglify不起作用

Question

我有一个使用gulp.task 'scripts' gulp-uglify gulp.task 'scripts' 。 然后，我还添加了gulp-import ，它没有用。 如果我只做uglify工作。 如果我只import它可以工作。 但是，如果我同时做两个都行不通。 这是函数：

gulp.task('scripts', function(){
    gulp.src([
            'testgulp/**/*.js', '!testgulp/**/_*.js', '!testgulp/**/*.min.js'
        ])
        .pipe(include()) //if I comment only this line, uglify works
            .on('error', console.log)
        .pipe(uglify()) //if I comment only this line, include works
        .pipe(rename({ suffix: '.min' }))
        .pipe(gulp.dest(function(file) { return file.base; }));

});

然后在终端上尝试同时执行以下操作时，我得到此响应：

/Applications/MAMP/htdocs/git/personal-sandrina-p/_main/v3/node_modules/map-stream/index.js:103
        throw err
        ^

我离开了Koala App，添加/添加功能很棒，所以我想对Gulp做同样的事情。 我尝试了gulp-include和gulp-import，两者都有相同的问题。 我做错了什么？ 谢谢 ：）

-编辑-我也尝试了gulp -sync并在minifyit任务上对timeout（）进行了硬编码，但无法解决问题...

好吧，我想我找到了问题。 首先，我需要安装gulp-util才能更好地找出错误所在。

gulp.task('scripts', function(){
    gulp.src([
            'assets/scripts/**/*.js',
            '!assets/scripts/**/_*.js',
            '!assets/scripts/**/*.min.js'
        ])
        .pipe(include())
            .on('error', console.log)
        .pipe(uglify().on('error', gutil.log)) //gulp-util
        .pipe(rename({ suffix: '.min' }))
        .pipe(gulp.dest(function(file) { return file.base; }));
});

然后是ES5速记uglify引发的错误。 我还必须安装gulp-babel，以及最终代码：

gulp.task('scripts', function(){
    gulp.src([
            'assets/scripts/**/*.js',
            '!assets/scripts/**/_*.js',
            '!assets/scripts/**/*.min.js'
        ])
        .pipe(include())
            .on('error', console.log)
        .pipe(babel({
            presets: ['es2015'], //this fixed a shorthand javascript error
            compact: true
        }))
        .pipe(uglify().on('error', gutil.log)) // gulp-util
        .pipe(rename({ suffix: '.min' }))
});

这解决了我的问题。 希望能帮助别人:)

您应该使用泵模块。

   var pump = require('pump');

   gulp.task('scripts', function(){
       pump([
          gulp.src([...]),
          ugilfy(),
          rename({ suffix: '.min' }),
          gulp.dest(...)
       ]);
   });

您会看到为什么使用泵

只需将它们作为单独的函数，并在丑陋的函数之前运行包含函数：

 gulp.task('include,function({
       // include code here
 });

 gulp.task('uglify',['include'],function({
          // uglify code here
 });

当您运行uglify函数时，[]之间的include函数将在uglify函数之前运行
