Centos 6.3 R安装报错

Question

我是 centos 新手，所以我尝试安装 R。它已安装，但在我编写控制台时出现此错误

Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/usr/lib64/R/library/utils/libs/utils.so':
/usr/lib64/R/library/utils/libs/utils.so: undefined symbol: libssh2_agent_disconnect In addition: Warning message: package "methods" in options("defaultPackages") was not found Error : package ‘grDevices’ does not have a namespace In addition: Warning messages: 1: package ‘utils’ in options("defaultPackages") was not found 2: package ‘grDevices’ in options("defaultPackages") was not found Error : package ‘grDevices’ does not have a namespace In addition: Warning message: package ‘graphics’ in options("defaultPackages") was not found Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/usr/lib64/R/library/methods/libs/methods.so':
/usr/lib64/R/library/methods/libs/methods.so: undefined symbol: libssh2_agent_disconnect In addition: Warning message: package ‘stats’ in options("defaultPackages") was not found During startup - Warning message: package ‘methods’ in options("defaultPackages") was not found

这个错误是怎么回事？我无法发挥任何作用。例如;

install.packages("test")

错误：找不到函数"install.packages"

谢谢

更新 libssh2 为我解决了这个问题

下面，我分享了我安装 R 的经验，因为我遇到了类似的问题，通过简单地更新 libssh2 软件包，经过相当多的鬼混后，该问题得到了解决！

安装了 R 版本 3，一旦启动，它会抛出各种关于加载共享对象失败的错误，每一个都以魔法错误 "undefined symbol: libssh2_exit" 结束，我试图找出这些对象有什么问题，并且我试图使用 ldconfig 强制加载它们，但我所有的尝试都是徒劳的！文件存在，而且它们看起来没有损坏

{
[root@Centos6-vtl-sb ~]# R

[root@Centos6-vtl-sb ~]# ls /usr/lib64/R/library/methods/libs/methods.so
/usr/lib64/R/library/methods/libs/methods.so
[root@Centos6-vtl-sb ~]#

}

最后我决定检查 libssh2 版本，发现我的版本是现代版本，更新后，那些错误就消失了
