Windows R：grImport ghostscript错误'状态127'

Question

我已经在R（Windows，Rstudio）中安装了Ghostscript和grImport。我正在学习本教程，但我立即收到错误消息，

> library(grImport)
Loading required package: grid
Loading required package: XML
> PostScriptTrace("petal.ps")
Error in PostScriptTrace("petal.ps") : 
  status 127 in running command 'gswin32c.exe -q -dBATCH -dNOPAUSE -sDEVICE=ps2write -sOutputFile=C:\Users\UsrNm\AppData\Local\Temp\RtmpsXXlWA\file1b5c623f48de -sstdout=petal.ps.xml capturepetal.ps'
In addition: Warning message:

任何帮助，将不胜感激。

我在Windows 10下遇到同样的问题，我通过手动将路径设置为ghostscript来解决了这个问题：

Sys.setenv(R_GSCMD = normalizePath("C:/gs/gs9.20/bin/gswin32c.exe"))
