<\/span><\/h3>\n\n\n\nOnce RubyGems is installed, you should update it to the latest version. To do this, run the following command:<\/p>\n\n\n\n
sudo gem update --system<\/code><\/pre>\n\n\n\nThis command will update RubyGems to the latest version available.<\/p>\n\n\n
\n
<\/span>Install RubyGems dependencies<\/span><\/h3>\n\n\n\nRubyGems requires some dependencies to function properly. To install these dependencies, run the following command:<\/p>\n\n\n\n
sudo apt-get install build-essential<\/code><\/pre>\n\n\n\nsudo apt install ruby-full<\/code><\/pre>\n\n\n\nThis command will install the necessary dependencies for RubyGems to function.<\/p>\n\n\n\n
<\/span>Verify the installation<\/span><\/h3>\n\n\n\nTo verify that RubyGems is installed correctly, run the following command:<\/p>\n\n\n\n
gem -v<\/code><\/pre>\n\n\n\nThis command should return the version number of RubyGems that you just installed.<\/p>\n\n\n\n
<\/span>Install a gem<\/span><\/h3>\n\n\n\nNow that RubyGems is installed and functioning properly, you can use it to install gems. To install a gem, run the following command:<\/p>\n\n\n\n
sudo gem install <gemname><\/code><\/pre>\n\n\n\nReplace <gemname><\/code> with the name of the gem you want to install. For example, to install the rails<\/code> gem, you would run the following command:<\/p>\n\n\n\nsudo gem install rails<\/code><\/pre>\n\n\n\nThis command will install the rails<\/code> gem and any necessary dependencies.<\/p>\n\n\n\n<\/span>Install the RubyGems on Linux (CentOS)<\/span><\/h3>\n\n\n\nUpdate your system<\/strong><\/p>\n\n\n\nBefore installing RubyGems, it is recommended to update your system to ensure that you have the latest software packages installed. To update your CentOS system, run the following command:<\/p>\n\n\n\n
sudo yum update<\/code><\/pre>\n\n\n\nInstall Ruby and RubyGems<\/strong> on Linux<\/p>\n\n\n\nCentOS comes with a version of Ruby installed by default, but it may not include RubyGems. To install Ruby and RubyGems on CentOS, run the following command:<\/p>\n\n\n\n
sudo yum install ruby rubygems<\/code><\/pre>\n\n\n\nThis command will install both Ruby and RubyGems on your system.<\/p>\n\n\n
\n
Verify the installation<\/strong><\/p>\n\n\n\nAfter installing Ruby and RubyGems, you can verify that they are installed correctly by running the following commands:<\/p>\n\n\n\n
[root@Virtono-Tutorials ~]# ruby -v\r\nruby 2.0.0p648 (2015-12-16) [x86_64-linux]\r\n[root@Virtono-Tutorials ~]# gem -v\r\n2.0.14.1\r\n[root@Virtono-Tutorials ~]#\r<\/code><\/pre>\n\n\n\nThese commands should return the version numbers of Ruby and RubyGems respectively.<\/p>\n\n\n\n
Install a gem<\/strong><\/p>\n\n\n\nTo install a gem using RubyGems on CentOS, you can use the same command as on other Linux distributions:<\/p>\n\n\n\n
sudo gem install <gemname><\/code><\/pre>\n\n\n\nReplace <gemname><\/code> with the name of the gem, you want to install. For example, to install the rails<\/code> gem, you would run the following command:<\/p>\n\n\n\nsudo gem install rails<\/code><\/pre>\n\n\n\nThis command will install the rails<\/code> gem and any necessary dependencies.<\/p>\n\n\n\nHow to fix the following error:<\/p>\n\n\n\n
[root@Virtono-Tutorials ~]# sudo gem install railsInstall a newer version of Ruby<\/p>\n\n\n\n
If your version of Ruby is older than 2.3, you will need to install a newer version. There are several ways to do this, but one of the most common is to use a Ruby version manager such as rvm<\/code> or rbenv<\/code>.<\/p>\n\n\n\n# sudo yum install -y git curl zlib-devel gcc-c++ patch readline readline-devel \\\nlibyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison sqlite-devel\n\n# git clone https:\/\/github.com\/rbenv\/rbenv.git ~\/.rbenv\necho 'export PATH=\"$HOME\/.rbenv\/bin:$PATH\"' >> ~\/.bashrc\necho 'eval \"$(rbenv init -)\"' >> ~\/.bashrc\nsource ~\/.bashrc\n\n# git clone https:\/\/github.com\/rbenv\/ruby-build.git ~\/.rbenv\/plugins\/ruby-build\n\n# rbenv install 2.3.8\n\n#rbenv global 2.3.8\n<\/code><\/pre>\n\n\n\nNote: Remove “#”<\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"In this article, we will discuss how to install RubyGems on Linux.
