What if gem install redis reports an error?

Editor to share with you how to do gem install redis error report, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

When you use the ruby script to install the Redis cluster, you need to install the Ruby locale and the redis plug-in first, but when you install the Ruby plug-in, you encounter the following error. Please note the resolution process below.

Because the Ruby locale is required to execute Ruby scripts, install the Ruby locale and Ruby's package manager Gems first.

Then use gem to install the interface between Redis and Ruby.

RubyGems is a package manager for Ruby that provides a standard format for distributing Ruby programs and libraries, as well as a tool for managing package installations.

RubyGems is designed to easily manage the tools installed by gem, as well as the servers used to distribute gem. This is similar to apt-get under Ubuntu and pip to yum,Python of Centos.
