20发行centos rgdal

Question

有人能帮我理解rgdal的问题吗？

我为centos 6 64位安装了gdal 2，但是我没有成功地安装rgdal。我试图弄清楚是什么问题，但我没有在网上找到任何有用的东西。

这是Rstudio-服务器控制台：

我试图安装gdal的依赖项并将libgdal.so.20复制到/user/lib64 64/ogdi，但没有成功!*

谢谢你的帮助

解决办法太简单了！CentOS找不到这些库，我只是将这些库复制到64个文件夹中。

cp /usr/local/lib/libgdal.so.20* /usr/lib64/

一切都像魔法一样运作！
