我的其中一个 Hugo 博客采用了 PaperMod 主题，另一个是 hugo-coder 主题，都是通过 Netlify 部署，昨天晚上发现，Netlify 显示 paper.191000.xyz 对应的站点部署失败。

解决方案 链接到标题
问题出在访问 https://github.com/adityatelange/hugo-PaperMod/tree/ea64dacc943c5a0d3163dd75dcc11d5e791a37b4 的结果已经是 404 了，大概就是 PaperMod 主题提交记录改变之类的原因导致的，而 Netlify 还在使用这个 sha 记录，解决方案也很简单，点击 retry -> Clear cache and deploy site 即可。
对于 Git 的细节我并不清楚，这里的问题原因看看就好。
