Run this command to list what are the available versions: rvm list known Now, we can use the RVM command to install and manage Ruby versions on our Debian Linux. If you have any issues while using RVM live in the server environment feel free to reach out to live support.After the installation, to let the system properly integrate the RVM home path to the system environment variable, either close the terminal app and open it again or simply reload the shell session using the given command: source ~/.bashrc However, you may encounter an error during the compilation phase. If you need to change the default server version of Ruby available in shared hosting it is possible to install RVM. In most cases, you will be able to manage a local Ruby application using RVM and upload it to your server. You will see an output similar this one: ruby 2.5.0p0 ( revision 61468) For example, if you want to use version 2.5.0 you can run the following command: rvm use 2.5.0Īnd you can check your version to make sure that you have successfully made the switch: ruby -v To switch from the system Ruby version to your desired version, you can run the use command. You can install any version of Ruby necessary to run your application. For example, to install version 2.5.0 you can run the following: rvm install 2.5.0 Once you have installed RVM, you can install multiple versions of Ruby by simply typing the version number. Install Multiple Ruby Versions In One System The dedicated Ubuntu setup will likely work well for any Debian-based Linux distribution. Some users may need to update their bash profile to include RVM command support.įor Mac and Windows, the standard installation should be sufficient. But basically, installation involves the running of a remote installation script. Installation of RVM may vary slightly depending on your operating system. These are instances in which the Ruby Version Manager can save you. Do you think you can easily switch back to the previous version until the bugs are worked out? Likely not. Likewise, imagine a routine system upgrade switches you to the newest version of Ruby, and this breaks a piece of software you use for work every day. A piece of software needs to be tested on the new version before comitting to it. But often, particularly for developers, upgrades can be costly. Or, why is this important, why does it matter? In general, it’s always best to run the latest and greatest versions of any mission-critical software. What’s The Point Of Having Multiple Ruby Versions? If you need to manage a different version of Ruby than the one installed on your system, you can use RVM to install and execute multiple versions. You can have multiple Ruby executables in different places. This means the Ruby executable file need not be only present at the system level. It uses an executable file to interpret your code and produce the proper output. Install Multiple Ruby Versions In One SystemĪs you may be aware, Ruby is an “interpreted” language. What’s The Point Of Having Multiple Ruby Versions?.RVM, the Ruby Version Manager, is a separate application you can install to easily switch between different versions of Ruby. And changing the default system version can be very difficult, so what are your options. This can be a big problem if your application depends on a specific version to run properly. Different workstations might have different versions of Ruby installed. Installing, using, or developing Ruby applications can vary from system to system.
