如果报错缺少某个依赖文件

1
ncl: error while loading shared libraries: lib***.so.X: cannot open shared object file: No such file or directory

则安装对应的依赖库即可，推荐使用 apt-file 寻找缺失文件所在的库

安装 apt-file 之前，添加 apt 的源

1

3
sudo vim /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ bionic main universe
sudo apt-get update

安装 apt-file

1
sudo apt-get install apt-file

更新 apt-file 数据库

1
sudo apt-file update

查找缺失文件 lib***.so.X 所在的库，这里以 libgfortran.so.3 为例

1
sudo apt-file search libgfortran.so.3

安装任何一个库即可解决问题

1
sudo apt-get install libgfortran3
