[Rapiz1]

Found the same issue here: https://github.com/hexojs/hexo/issues/1913
Why should I set auto_detect to false?

[NoahDragon]

The auto_detect is set for detecting language automatically, https://github.com/hexojs/hexo-util#highlightstr-options

I assume the issue is caused by when the highlight.js tries to detect the code language.

[dreambo8563]

got the same issue, after change the
```scala xx ```
to
```js xxx ```
hexo is back

[jongio]

Setting auto_detect: false in _config.yml resolved this for me:

_config.yml

highlight: 
  enable: true
  line_number: false
  auto_detect: false
  tab_replace:

[marcofranssen]

The solution provided here just gives me another error. See my ticket #3486 with some more details and ideas to finally find a real solution to this issue.

[MrConfused]

这是因为在你的博客中，在用代码段`````时没有指明语言，这时候如果你的auto_detect: true，就会产生这个错误。
解决的话：

1. 找到那篇文章没有指明语言，随便加上一个就行。
2. 如果找不到哪篇博客，
   2.1 可以在\myBlognode_modules\hexo\lib\hexorender.js中的第51、52行加上
   console.log(data.path);
   console.log(data.text);
   查看在哪篇博客之后出现的问题。
   2.2 然后，设置auto_detect: false，运行hexo g，查看生成文章的顺序，在2.1找到的文章之后的那篇文章，基本就是你没有指明语言的文章了。
   2.3 此时给他随便指明一个语言，然后可以吧render.js中加的两行删掉，设置auto_detect: true，运行hexo clean，hexo g即可解决
