RHEL7.2 安装Texlive2016时出现Can't locate Digest/MD5.pm的解决方法

问题：

在将texlive2016.iso挂载到/mnt后，进入/mnt目录

$ cd /mnt

$ sudo ./install-tl

之后遇到如下错误：

Can't locate Digest/MD5.pm in @INC (you may need to install the Digest::MD5 module) (@INC contains: ./tlpkg /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at tlpkg/TeXLive/TLUtils.pm line 201.

BEGIN failed--compilation aborted at tlpkg/TeXLive/TLUtils.pm line 201.
Compilation failed in require at ./install-tl line 53.

BEGIN failed--compilation aborted at ./install-tl line 53.

解决方法：

摸索了一会，发现这样可以解决问题。

$ sudo yum install perl-Digest-MD5
