有人可以帮我理解 rgdal 的问题是什么吗？
我为centos 6 64位安装了gdal 2，但没有成功安装rgdal。
我试图找出问题所在，但在互联网上没有找到任何有用的信息。
这是 Rstudio 服务器控制台：
install.packages("rgdal")

我尝试安装 gdal 的依赖项并将 libgdal.so.20 复制到 /user/lib64/ogdi 但没有成功！*
感谢您的帮助
解决方案就是这么简单！
CentOS找不到这些库，我只是将这些库复制到64文件夹中。
cp /usr/local/lib/libgdal.so.20* /usr/lib64/
一切都像魔法一样！
