R安装stringi失败

Question

我试图调用knit，它告诉我它需要更新版本的rmarkdown，它需要包stringi。

在安装stringi时，我会得到以下错误：

> install.packages("stringi")

Installing package into ‘C:/Users/matan/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)

  There is a binary version available but the source version is later:
        binary source needs_compilation
stringi  1.1.5  1.1.6              TRUE

  Binaries will be installed
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.4/stringi_1.1.5.zip'
Warning in install.packages :
  cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/3.4/stringi_1.1.5.zip': HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) : 
  cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/3.4/stringi_1.1.5.zip'
Warning in install.packages :
  download of package ‘stringi’ failed

我怎样才能解决这个问题，这样我才能最终和平地knit我的.RMD？

编辑(解决方案)

1. 从stringi_1.1.6.zip下载windows二进制文件(r-release：https://cran.r-project.org/web/packages/stringi/index.html )
2. 由> install.packages(".../Downloads/stringi_1.1.6.zip", repos = NULL, type = "source")安装

最简单的解决方案是从.zip下载这里或.tar.gz文件，并选择在RStudio工具->安装包中安装.，请更改install : to packages并选择您下载的文件。
