Question

在下面运行gulp任务时，我从JSmin获得以下错误消息：

/var/www/html/a/node_modules/gulp-jsmin/node_modules/jsmin-sourcemap/node_modules/jsmin2/lib/jsmin.c.index.js:40
          stream.write(str);
                 ^

          // Add the error to output

        } has no method 'write'

/ ** Gulp任务** /

gulp.task('js', function() {
    gulp.src('app/assets/javascripts/**/*.js')
        .pipe(changed('public/assets/javascripts/min'))
        .pipe(jsmin())
        .pipe(rename({suffix: '.min'}))
        .pipe(gulp.dest('public/assets/javascripts/min'));

    gulp.src([  'public/assets/javascripts/min/bootstrap.min.js','public/assets/javascripts/min/jquery.flexslider.min.js','public/assets/javascripts/min/waypoints.min.min.js',
            'public/assets/javascripts/min/modernizr.custom.min.js','public/assets/javascripts/min/jquery.stapel.min.js', 'public/assets/javascripts/min/jquery.socialist.min.js',

            'public/assets/javascripts/min/jquery.masonry.min.min.js', 'public/assets/javascripts/min/functions.min.js'])
        .pipe(concat('application.js'))
        .pipe(gulp.dest('public/assets/javascripts/min/'));
});

有人可以帮我弄清楚发生了什么吗？

简短的回答是node-jsmin2模块中有一个错误，自修订版7d5f486f46b453d738057e97060e4805846bf4af以来引入。

在该修订版中，fputs已修改为调用stream.write(str)而不是stream(str)，stdout被修改为包含write和{{{的对象1}}方法 - 但writeFromIndex未进行类似修改。（该提交，BTW，意味着stderr和stdout的默认值，即stderr和console.log不再适合。{{{{ 1}}更改提交。）

这是一个快速的“修复”（我打算发送拉取请求，但决定反对）：

console.error
