直到最近R升级后奇怪的事情才开始发生,我在Ubuntu 14.04上是一个快乐的StatET用户.与网络操作相关的任何内容都将失败 例如,我无法再从CRAN安装软件包:
> install.packages("Hmisc")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---
Error in url("http://cran.r-project.org/CRAN_mirrors.csv") :
internet routines cannot be loaded
In addition: Warning message:
In url("http://cran.r-project.org/CRAN_mirrors.csv") :
unable to load shared object '/usr/lib/R/modules//internet.so':
/usr/lib/R/modules//internet.so: symbol curl_multi_wait, version CURL_OPENSSL_3 not defined in file libcurl.so.4 with link time reference
如果我在终端中运行R,它会顺利运行:
> install.packages("Hmisc")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
trying URL 'http://cran.at.r-project.org/src/contrib/Hmisc_3.16-0.tar.gz'
Content type 'application/x-gzip' length 629536 …我在更新R后在CentOS上的R中安装软件包时遇到了一些麻烦.下面是我尝试在R中安装软件包时会发生什么的示例:
> install.packages("ggplot2")
Installing package into '/home/albers/R/x86_64-pc-linux-gnu-library/3.2'
(as 'lib' is unspecified)
--- Please select a CRAN mirror for use in this session ---
