报错原因
缺少zlib库依赖
解决报错
1 首先安装zlib库
yum install zlib-devel
2 集成zlib库到Ruby环境
进入到相关目录# cd ruby-2.3.8/ext/zlib # ruby extconf.rb checking for deflateReset() in -lz... yes checking for zlib.h... yes checking for crc32_combine() in zlib.h... yes checking for adler32_combine() in zlib.h... yes checking for z_crc_t in zlib.h... yes creating Makefile # make linking shared-object zlib.so # make install /bin/install -c -m 0755 zlib.so /usr/local/ruby/lib/ruby/site_ruby/2.3.0/x86_64-linux
