今天我新写了一篇文章，在生成静态页面的时候会出错。如果我把这篇文章，从(_posts)目录删除，却可以正常执行hexo g。
请求指导我该如何解决这个问题！

I found the problem. I think this is a bug but we can avoid it.

For example...

``` (tab character)
Hello world
```

If you write a tab character instead of language name, The same error will occur.
The characters these meet all of below three conditions will cause this.

• It is not white space (" ").
• It is not line break.
• But it matches \s of regular expression.

Tab character matches these conditions.

When you remove unnecessary characters, that error will be solved... I think.

很感谢你的帮助。

问题果然如你所说是在（``` (tab character))这个地方多了一个空格键，删除之后再次（hexo g）没有错误提示了。

I appreciate your help.
The problem really is, as you say in (`` `(tab character)) this place more than a spacebar, then removed again (hexo g) no error prompted.
