r - R Studio 安装 stringi 失败

Question

我正在尝试调用knitwhich 告诉我它需要更新版本，rmarkdown它需要 package stringi。

安装时stringi出现以下错误：

> 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

我该如何解决这个问题，这样我才能最终knit平静.RMD下来？

编辑（解决方案）：

1. 从以下位置下载 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")

Answer 1

最简单的解决方案是从此处下载.zip或.tar.gz文件并在 RStudio Tool -> Install packages...中选择安装它，将Install from:更改为Package Archive File并选择您下载的文件。
