Miktex did not succeed after I updated R to version 3.5.0

问题

After I updated R to version 3.5.0, I couldn't start my MikTex from Rstudio,

---
output:
  pdf_document:
    latex_engine: xelatex 
    includes:
      in_header: header.tex
    keep_tex: yes
---

Above is the code I typed ahead of my Rmd, and after knitring,

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

Information showed in xelatex.log:

And after I tried:

Sys.which("xelatex")

                                    xelatex 
"D:\\miktex\\miktex\\bin\\x64\\xelatex.exe"

Sys.setenv("PATH" = "D:\miktex\miktex\bin\x64\xelatex.exe" )

then knitr again:

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)

Could anyone help? Thanks.

回答1:

as mentioned, you can change the default setting and let MiKTeX install the missing LaTeX packages without asking:

From the MiKTeX Console → settings → “Always install missing packages on-the-fly”.
