    My Centos version was 7.6 and all provided solution for nokogiri was not working. Finally i updated centos to 7.8 and it worked. i tried with centos 7.7 version in other server also, it worked on 7.7 also.

    i encountered exactly same problem.
    It seems that the real error is

    /usr/bin/ld: unrecognized option ‘–compress-debug-sections=zlib’

    The flag "–compress-debug-sections=zlib" is defined in file /usr/local/rvm/gems/ruby-2.7.0/gems/nokogiri-1.10.10/ext/nokogiri/Makefile .
    This makefile is created by a mkmf.rb, and default value of flags are in this file /usr/local/rvm/rubies/ruby-2.7.0/lib/ruby/2.7.0/x86_64-linux/rbconfig.rb

    CONFIG["DLDFLAGS"] = "-Wl,–compress-debug-sections=zlib"

    After I changed this line to be

    CONFIG["DLDFLAGS"] = ""

    gem install nokogiri works well

    But I am not sure about the exactly function of flag "–compress-debug-sections=zlib" and what would happen when i removed it

    as far as my version of centos is old and /usr/bin/ld is a part of binutils, so my suggestion

    $ sudo yum update binutils

    helped me (instead of full OS update)

    This error comes because the default linker on Centos 7.4 does not support that option --compress-debug-sections=zlib. Centos 7.8 seems to fix this issue.

    But in case you could not switch to Centos 7.8, the option is supported by the gold linker (ld.gold).

    To enable the use, you could override the linker by doing something like

    ln -s /bin/ld.gold ~/bin/ld; PATH=~/bin:$PATH

    then run the needed command
