r - 在 R 中安装 RSelenium 时出错

Question

当我尝试安装 RSelenium 时出现以下错误包裹。

install.packages("RSelenium")  
Installing package into ‘C:/Users/nshukla/Documents/R/win-library/3.2’
(as ‘lib’ is unspecified)  
Warning in install.packages :  
  dependency ‘binman’ is not available  
also installing the dependencies ‘subprocess’, ‘semver’, ‘wdman’

There is a binary version available but the source version is later:
             binary source needs_compilation  
  RSelenium  1.6.2  1.7.1             FALSE    

Packages which are only available in source form, and may need compilation of C/C++/Fortran:  
  ‘subprocess’ ‘semver’  
  These will not be installed
installing the source packages ‘wdman’, ‘RSelenium’

binman包进口semver解析语义版本字符串。这取决于 C++11。安装它需要 R >= 3.3.0 的版本。您需要升级您的 R 版本。
