Question

尝试在本地计算机上构建此gitbook时遇到以下错误（试图将其用作创建自己的工作的模板）：

https://github.com/lgatto/IntroMachineLearningWithR

错误：

Error in x[i] <- sprintf("<a href=\"%s#%s\"", filenames[which.max(lines[lines <= : replacement has length zero

Calls: <Anonymous> ... <Anonymous> -> split_chapters -> restore_links -> lapply -> FUN

还会出现以下警告，但这对修复任务的重要性可能较小：

In addition: Warning message: In split_chapters(output, gitbook_page, number_sections, split_by, : You have 6 Rmd input file(s) but only 5 first-level heading(s). Did you forget first-level headings in certain Rmd files?

我对此游戏很晚，但是请确保您要编织的.rmd文件中的第一级标题为headers.Select((name, index) => new { name, index }) .AsParallel() .ForAll ( header => { switch (header.name) { case "First": firstColumn = header.index; break; case "Second": secondColumn = header.index; break; } } );，而不是#或{{1 }} 等等。我遇到了同样的错误，这为我解决了。
