今天按照教程成功在本地可以通过blogdown::serversite()预览到写好的网页，但是在build之后将public文件夹上传到github之后然后使用netlify部署过程中出错了，并且报错再别处都没有找到。

这里面好像是说缺少模板文件，可是我是按照教程都上传到github仓库中了，不知道大家有什么解决方法，不胜感激。

    yihui 您好，使用checksite之后弹出的to do 如下
    ― Checking config.yaml
    | Checking "baseURL" setting for Hugo...
    ● [TODO] Update "baseURL" to your actual URL when ready to publish.
    | Checking "ignoreFiles" setting for Hugo...
    ○ "ignoreFiles" looks good - nothing to do here!
    | Checking setting for Hugo's Markdown renderer...
    ○ All set! Found the "unsafe" setting for goldmark.
    ― Check complete: config.yaml
    请问这个baseURl是在config.yaml的那里添加，并且具体添加什么内容，不胜感激

        g853346463 这个 baseURL 倒不是大问题。真正的问题是有个文件 layouts/shortcodes/blogdown/postref.html 你没有提交到 Github 库中。我上面说 blogdown::check_site() 应该会自动指出来这个问题，是因为我有专门的代码来检查这个常见问题：https://github.com/rstudio/blogdown/blob/00a2090/R/check.R#L142-L160 我不明白为什么在你这个网站里没能查出来。这个 postref.html 文件是否存在？理论上是应该存在的（自动生成的）。

        若你要是有基本的排错技能，你可以帮我看看为什么这个问题漏网了：

        debug(blogdown::check_gitignore)
blogdown::check_site()

        运行到 if (Sys.which('git') != '' && system2_quiet('git', 'status') == 0) { 那一行时，看为什么 x8 没有将 x7 加进去。

            yihui 您好，我看了下我的repo里面是有postref.html这个文件存在的。通过增加baseURL解决了上述问题。您提到的没有报错的我通过您提出的方法找到了源代码，初步感觉是没有将x7的值赋给x8，但是我个人编程能力很差，也有可能说错了。源码如下：
            if (Sys.which("git") != "" && system2_quiet("git", "status") ==
            0) {
            msg_next("Checking for files required by blogdown but not committed...")
            x7 = c("layouts/shortcodes/blogdown/postref.html")
            x8 = NULL
            for (i in x7) {
            if (!file_exists(i))
            next
            if (system2_quiet("git", c("ls-files", "--error-unmatch",
            i)) != 0)
            x8 = c(x8, i)
            }
            if (n <- length(x8)) {
            msg_todo("Found ", n, " file", if (n > 1)
            "s", " that should be committed in GIT:\n\n",
            indent_list(x8))
            }
            else {
            msg_okay("Great! Did not find such files.")
            }
            }
            msg_done(f)
            }

              CyrusYip 感谢，因为对netlify的工作原理不是很懂，就一股脑都上传上去了 😃
