[Bestfeel]

这个没有写正确吧

[XuYanci]

in _posts ,if there is no file , it will cause this error .

[hansomesong]

I have encountered the same issue.

I think the cause is: incompatibility of plugins: hexo-generator-sitemap, hexo-generator-feed and hexo3.

So when I comment the two aforementioned plugins, the command "hexo g" passed!

[jzm1994]

插件 hexo-generate-feed 还有 hexo-generate-sitemap 和 hexo3 不兼容！

[HJHL]

I have encountered the same problem too. Finally I find it's because I deleted all the posts in source/_post/

[kobe-tian]

I have encountered the same problem too. But i have file in source/_posts/index.md when i start hexo s -debug, i got this error:
