为什么要安装"igraph"R中的软件包在加载时显示错误? [英] Why installed "igraph" package in R is showing error upon loading?

问题描述

我试图使用命令install.packages("igraph")在R中安装igraph软件包.安装后，在测试阶段它显示以下错误:

I was trying to install the package igraph in R using the command install.packages("igraph"). After the installation, during testing phase it showed the following error:

Warning message:

为什么会这样?有什么解决办法?

Why this is happening? What could be a solution?

推荐答案

igraph需要库文件，例如libicui18n.so.58，libicuuc.so.58，libgfortran等.这些文件未安装在正确的库文件夹中，或者作为以前的版本存在.例如，以我为例，需要在"usr/lib64"中安装libicuuc.so.58.确保正确安装了依赖项才能解决此类问题.

igraph require library files such as libicui18n.so.58, libicuuc.so.58, libgfortran etc. These were either not installed in the proper library folder or were existing as previous versions. For example, in my case, libicuuc.so.58 was required to be installed in 'usr/lib64'. Make sure that dependencies are installed correctly to solve such problems.
