关于hexo标题问题

今天出于让hexo更优雅的目的，修改了一下配置，给默认模板加上了categories属性。

之前的新建文章，是用hexo new 2017-7-27这样的命令。由于默认情况下文件名=标题，因此会出现用日期命名的.md文件，再进行编辑。

本想直接在hexo的_config.yml中，把文件名改为用时间命名，这样就能用hexo new 标题的命令，简化流程。

然而在本地调试的时候出现了错误：

ValidationError: `slug` is required!

这就很尴尬了……最后把_config.yml中new_post_name的值改为:year-:i_month-:day-:title.md # File name of new posts，问题解决。

应该是hexo不允许这样做（不会自动处理重复命名。）
