Dek*_*eku 5 r miktex knitr r-markdown
在我将 R 更新到 3.5.0 版本后，我无法从 Rstudio 启动我的 MikTex，
---
output:
pdf_document:
latex_engine: xelatex
includes:
in_header: header.tex
keep_tex: yes

以上是我在 Rmd 之前输入的代码，在编织之后，
Sorry, but D:\miktex\miktex\bin\x64\xelatex.exe did not succeed.
The log file hopefully contains the information to get MiKTeX going again:
C:/Users/DELL/AppData/Local/MiKTeX/2.9/miktex/log/xelatex.log
xelatex.log 中显示的信息：
2018-04-29 10:06:17,482+0800 FATAL xelatex - Info:

在我尝试之后：
Sys.which("xelatex")
xelatex
"D:\\miktex\\miktex\\bin\\x64\\xelatex.exe"
Sys.setenv("PATH" = "D:\miktex\miktex\bin\x64\xelatex.exe" )
然后再次编织：
Warning messages:
1: In system2(..., stdout = FALSE, stderr = FALSE) : '"xelatex"' not found
2: In system2(...) : '"xelatex"' not found
No TeX installation detected (TeX is required to create PDF output). You should install a recommended TeX distribution for your platform:
Windows: MiKTeX (Complete) - http://miktex.org/2.9/setup
(NOTE: Be sure to download the Complete rather than Basic installation)
有人可以帮忙吗？谢谢。
