node.js - Gulp-Imagemin 的 EACCES 错误

Question

我正在尝试执行 gulp 任务，但收到此错误:

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)

它没有说明错误本身，所以我安装了“superstack”并得到了这个:

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)

    at writeOrBuffer (/var/www/public/node_modules/gulp-imagemin/node_modules/through2-concurrent/node_modules/through2/node_modules/readable-stream/lib/_stream_writable.js:312:5)

知道为什么我会收到此错误吗？我可以做什么来修复它？

非常感谢!

编辑:

这是我正在尝试运行的任务。

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'));
});

这是一个权限错误。确保您拥有对所有这些文件和目录的读写访问权限。
