使用Gulp-Imagemin的EACCES错误

Question

我试图让一项“吞食”的任务奏效，但我得到了这个错误：

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn EACCES
    at errnoException (child_process.js:988:11)
    at Process.ChildProcess._handle.onexit (child_process.js:779:34)

它对错误本身并没有太多的说明，所以我安装了“超级堆栈”，得到了以下结果：

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn EACCES
    at errnoException (child_process.js:988:11)
    at Process.ChildProcess._handle.onexit (child_process.js:779:34)

知道我为什么会犯这个错误吗？我能做些什么来解决这个问题？

非常感谢!

编辑：

这就是我想要执行的任务。

gulp.task('build-images', function(){
    return gulp.src('app/assets/src/**/*.+(png|jpg|gif|jpeg)')
        .pipe($.debug({title:'BEFORE'}))
        .pipe(imagemin({
            progressive: true,
            svgoPlugins: [{removeViewBox: false}],
            use: [pngquant()]
        }))
        .pipe($.debug({title:'AFTER'}))
        .pipe(gulp.dest('dest/images'));
});

这是权限错误。确保您对所有这些文件和目录都有读写访问权限。
