R Studio安裝stringi失敗

Question

我正在嘗試調用knit ，告訴我它需要更新版本的rmarkdown ，需要包stringi 。

安裝stringi出現以下錯誤：

> 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

我該如何解決這個問題，以便最終能夠和平地knit我的.RMD ？

編輯（解決方案） ：

1. 從https://cran.r-project.org/web/packages/stringi/index.html下載windows binary（r-release：stringi_1.1.6.zip）
2. 安裝> install.packages(".../Downloads/stringi_1.1.6.zip", repos = NULL, type = "source")
