直到最近，当 R 升级后奇怪的事情开始发生时，我一直是 Ubuntu 14.04 上 StatET 的快乐用户。任何与网络操作相关的事情都会失败。例如，我不能再从 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，它可以顺利运行：
> install.packages("Hmisc")
Installing package into ‘/usr/local/lib/R/site-library’

这里会有什么问题？我怎样才能让它再次工作？
