R：无法安装 igraph 包

Question

I've been trying installing R package igraph but during installation I keep receiving the following error:

** libs
gfortran -fno-optimize-sibling-calls  -fpic  -g -O2  -c AMD/Source/amd.f -o AMD/Source/amd.o
make: gfortran: No such file or directory
make: *** [/usr/lib64/R/etc/Makeconf:191: AMD/Source/amd.o] Error 127

I've tried both installing from CRAN and from github repository with the same result. It seems that during installation there is an error on level of compiling C igraph library. I've also tried pre-compiling it but it doesn't work. File AMD/Source/amd.f is present in igraph repository.

Here is my sessionInfo :

I'd be grateful for any suggestion.

正如@r2evans 在他的评论中所建议的那样，答案很简单：我需要安装gfortran ，我误解了错误消息......这就是所有人！
