Question

将R从3.1.3升级到3.2.1后，我无法从CRAN安装软件包。错误消息是无法加载共享对象internet.so。

install.packages("randomForest")

以下帖子似乎解决了类似的问题。 Error in install.packages: internet routines cannot be loaded using StatET while it works in R console

固定！谢谢@David Robinson的建议。他们让我走上正轨。

我刚刚将以下命令添加到.bash_profile，问题解决了：

export LD_LIBRARY_PATH=$TOOLS/curl-7.43.0/lib:$LD_LIBRARY_PATH

R-3.2.1无法加载共享对象internet.so.
