Updating Ruby can be a bit tricky, but it's important to keep your version of Ruby up to date in order to take advantage of the latest features and security fixes. In this article, we'll walk through the process of updating Ruby, including code examples and tips to help you along the way.
First, it's important to note that there are two main ways to update Ruby: using a package manager (such as rbenv or RVM) or manually installing the latest version. We'll cover both methods in this article.
Updating Ruby with a package manager:
If you're using rbenv, you can update Ruby by running the following command:
rbenv install <version>
For example, to update to the latest version of Ruby, you can run:
rbenv install 2.7.3
Alternatively, if you're using RVM, you can update Ruby by running the following command:
rvm install <version>
For example, to update to the latest version of Ruby, you can run:
rvm install 2.7.3
Manually Installing the latest version of Ruby:
To manually install the latest version of Ruby, you'll first need to download the source code from the Ruby website (https://www.ruby-lang.org/en/downloads/). Once you've downloaded the source code, you can use the following commands to install it:
tar -xzvf ruby-2.7.3.tar.gz
cd ruby-2.7.3
./configure
make
make install
Please note that you need to have the necessary permissions to run the command "make install"
Once you've successfully installed the new version of Ruby, you'll need to update your system's PATH to point to the new version. You can do this by adding the following line to your shell profile (such as .bash_profile or .zshrc):
export PATH="/usr/local/bin:$PATH"
It's also a good idea to run the following command to make sure that your system is using the correct version of Ruby:
ruby -v
This command should return the version number of the Ruby installation that you just updated to.
In conclusion, Updating Ruby is an important task that helps you take advantage of the latest features and security fixes. It can be done either by using a package manager (such as rbenv or RVM) or manually installing the latest version. The process of updating Ruby may vary depending on the method you choose, but with the help of this guide and the provided code examples, you should be able to update Ruby with ease.
RVM (Ruby Version Manager)
RVM is a command-line tool that allows you to easily install, manage, and work with multiple versions of Ruby on the same machine. It is a popular tool among Ruby developers, as it makes it easy to switch between different versions of Ruby and manage dependencies for different projects.
To install RVM, you can use the following command:
\curl -sSL https://get.rvm.io | bash -s stable
Once RVM is installed, you can use the following command to see a list of all the versions of Ruby that are available:
rvm list known
You can install a specific version of Ruby by running the following command:
rvm install 2.7.3
You can also use RVM to set a default version of Ruby for your system:
rvm --default use 2.7.3
This command will set the default version of Ruby to 2.7.3, which means that any new terminal sessions will automatically use this version.
RVM also has a feature called gemsets, which allows you to create isolated environments for different projects. This is useful if you have different projects that require different versions of gems. You can create a new gemset by running the following command:
rvm gemset create my_project
You can then use the following command to switch to the my_project gemset:
rvm gemset use my_project
rbenv
rbenv is a command-line tool similar to RVM, but it is designed to be simpler and less invasive. It allows you to easily install, manage, and work with multiple versions of Ruby on the same machine.
To install rbenv, you can use the following command:
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
Once rbenv is installed, you can use the following command to see a list of all the versions of Ruby that are available:
rbenv install -l
You can install a specific version of Ruby by running the following command:
rbenv install 2.7.3
You can also use rbenv to set a default version of Ruby for your system:
rbenv global 2.7.3
This command will set the default version of Ruby to 2.7.3, which means that any new terminal sessions will automatically use this version.
rbenv also has a plugin called ruby-build, which allows you to easily install new versions of Ruby.
In conclusion, both RVM and rbenv are popular tools among Ruby developers, and both make it easy to install, manage, and work with multiple versions of Ruby. They both have similar features such as installing different versions of Ruby, setting a default version and creating isolated environments for different projects. RVM is a bit more advanced and provides more features, while rbenv is simpler and less invasive. You can choose the one that best fits your needs and preferences.
