  请问这个问题怎么办？

  installing the source package ‘stringi’

  
  

  trying URL 'http://cran.rstudio.com/src/contrib/stringi_1.2.2.tar.gz'

  Content type 'application/x-gzip' length 7270627 bytes (6.9 MB)

  downloaded 6.9 MB

  
  

  * installing *source* package 'stringi' ...

  ** 成功将'stringi'程序包解包并MD5和检查

  Warning in system("sh ./configure.win") : 'sh' not found

  ERROR: configuration failed for package 'stringi'

  * removing 'D:/program files/R language/R-3.5.0/library/stringi'

  In R CMD INSTALL

  Warning in install.packages :

    installation of package ‘stringi’ had non-zero exit status

  
  

  The downloaded source packages are in

  ‘C:\Users\Michael\AppData\Local\Temp\RtmpQXf6bD\downloaded_packages’
