Centos 6.3 R安装错误

Posted 2021-04-04

我是新手centos所以我试图安装R.它已安装但在我编写控制台时出现此错误

R

dyn.load中的错误（文件，DLLpath = DLLpath，...）：无法加载共享对象'/usr/lib64/R/library/utils/libs/utils.so'： /usr/lib64/R/library/utils/libs/utils.so:undefined symbol：libssh2_agent_disconnect另外：警告消息：找不到选项中的“方法”包（“defaultPackages”）错误：包'grDevices'没有命名空间另外：警告消息：1：未找到选项中的包'utils'（“defaultPackages”）2：未找到选项中的包'grDevices'（“defaultPackages”）错误：包'grDevices'没有命名空间另外：警告消息：未找到选项中的“图形”包（“defaultPackages”）dyn.load中的错误（文件，DLLpath = DLLpath，...）：无法加载共享对象'/ usr / lib64 / R /library/methods/libs/methods.so“： /usr/lib64/R/library/methods/libs/methods.so:undefined symbol：libssh2_agent_disconnect另外：警告消息：未找到选项中的包'stats'（“defaultPackages”）启动期间 - 警告消息：包'方法未找到'in options（“defaultPackages”）

这个错误是什么？我没有任何功能。例如;

install.packages("test")

错误：找不到函数“install.packages”

谢谢

答案

更新libssh2为我解决了这个问题

下面，我分享我安装R的经验，因为我有一个类似的问题，这是通过简单地更新libssh2包后解决了一些！

安装R版本3，一旦启动它会抛出有关未能加载共享对象的各种错误，每个错误都以魔术错误“未定义符号：libssh2_exit”结束，我试图找出这些对象有什么问题，我试图强制使用ldconfig加载它们，但我所有的尝试都是徒劳的！文件存在，无论如何它们看起来都不会被破坏

/usr/lib64/R/library/methods/libs/methods.so

}

最后我决定检查libssh2版本，发现我的版本是现代版本，一旦我更新它，那些错误就消失了
