R Studio安装stringi失败

Question

我正在尝试调用knit,它告诉我它需要一个rmarkdown需要包的更新版本stringi.

安装时stringi我收到以下错误:

> 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,所以我终于可以knit我的.RMD平安？

编辑(解决方案):

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

最简单的解决方案是从这里下载.zip或.tar.gz文件并在RStudio 工具中选择安装它- > 安装包...,将安装从:更改为包存档文件并选择下载的文件.
