cenos 8 安装官方源gmt失败

cenos 8 安装官方源gmt失败

主要步骤如下：

sudo yum install epel-release
sudo yum install yum-plugin-copr   （个人软件仓库集合）
sudo yum copr enable genericmappingtools/gmt   （启用GMT官方仓库）
sudo yum install gmt

但是出现依赖错误，
gmt-6.0.0-1.el8.x86_64 requires libnetcdf.so.15()(64bit), but none of the providers can be installed

以下是安装过程：

[zhao@zhaozhonghai ~]$ sudo yum install epel-release

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Error: 
 Problem: package gmt-6.0.0-1.el8.x86_64 requires libnetcdf.so.15()(64bit), but none of the providers can be installed
  - conflicting requests
  - nothing provides libsz.so.2()(64bit) needed by netcdf-4.7.0-2.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

https://centos.pkgs.org/8/centos-powertools-x86_64/libaec-1.0.2-3.el8.x86_64.rpm.html
解决方式是：在这个网址，下载了libaec-1.0.2-3.el8.x86_64.rpm，安装后，在执行之前的gmt安装命令就OK了。
