zlib not detected by `gem install redis`












0















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.
