在 RStudio 中使用 knitr 生成 .pdf 时出错

如何解决在 RStudio 中使用 knitr 生成 .pdf 时出错

我从 RStudio 创建了一个新文件 File / New File / R Markdown，我尝试将 .pdf 文件从 knitr / knitr 生成为 PDF，并且出现了我在下面重现的错误，我从 LaTeX 开始我不太清楚是什么牌子。感谢您的帮助。

控制台 RStudio：

! Sorry,but C:\Users\JOSCAR~1\AppData\Local\Programs\MIKTEX~1.9\miktex\bin\x64\pdflatex.exe did not succeed.

! The log file hopefully contains the information to get MiKTeX going again:

!   C:\Users\JoséCarlos\AppData\Local\MiKTeX\2.9\miktex\log\pdflatex.log

Error: LaTeX Failed to compile test.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See test.log for more info.
