zlib not detected by `gem install redis`

Having issue with making gem install to detect zlib.

I'm trying to install redis api for ruby. This needs zlib. Installed zlib through yum - sudo yum install zlib. Installation is successful (as below).

[~]$ sudo yum install zlib
Loaded plugins: fastestmirror, langpacks, versionlock
Loading mirror speeds from cached hostfile
 * base: server>.com
 * epel: server>.com
 * extras: <server>.com
 * hp: server>.com
 * updates: server>.com
Package zlib-1.2.7-17.el7.x86_64 already installed and latest version
Nothing to do

But, gem install redis couldn't detect zlib. I get below error when installing redis api.

[~]$ sudo gem install redis
ERROR:  Loading command: install (LoadError)
    cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

Any reason why gem install couldn't detect the zlib?

I suspect you're missing the devel package for zlib. rpm -qa | grep zlib should produce output like the following:

# rpm -qa | grep zlib
zlib-devel-1.2.7-15.el7.x86_64
zlib-1.2.7-15.el7.x86_64

You'll want to include zlib-devel and then try re-installing the redis gem. If this doesn't solve your issue, please include the output of gem install redis --verbose in your question.
