Question

我用

var cmq = require('gulp-combine-media-queries')

gulp.task('cmq', function () {
gulp.src('css/style.css')
.pipe(cmq({
  log: true
}))
.pipe(gulp.dest('dist'));
});

在gulp命令后输出此错误：

File css/style.css found.
buffer.js:169
throw new TypeError('must start with number, buffer, array or 
string');
  ^

节点 - 4.2.6，Gulp 3.9.1，npm - 3.5.2 我还使用了另一个npms来分组媒体并且具有相同的错误。我读了许多同样问题的文章，但没有人帮助

Answer 1

查看媒体查询代码（https://github.com/konitter/gulp-combine-media-queries/blob/master/index.js）

我可以看到您的文件“css/style.css”无法通过gulp访问，因此错误。

请重新检查路径并重试

Gulp组媒体错误＆＃34;必须以数字，缓冲区，数组或字符串＆＃34;开头。
