Rtools安装过程中下载检验包报错

Question

R、Rstudio、Rtools均安装在D盘上

输入Sys.which("make")可以得到"D:\rtools43\usr\bin\make.exe"
但是当试图下载试验包时出现

> install.packages("jsonlite", type = "source")

Warning in install.packages :
  安装程序包‘jsonlite’时退出狀態的值不是0

下载的程序包在
    ‘C:\Users\XXX\AppData\Local\Temp\RtmpA1gMd4\downloaded_packages’里

实在是找不到解决办法，求指点QAQ

犯了一个很愚蠢的错误，Rtool、R、Rstudio版本不匹配
