compiler version at runtime
To determine the compiler version of Ruby at runtime, you can use the RUBY_VERSION
constant. This constant returns a string representing the version of Ruby that is currently running.
Here are the steps to retrieve the compiler version at runtime:
Use the
RUBY_VERSION
constant: In your Ruby code, you can access theRUBY_VERSION
constant to get the version of the Ruby interpreter that is running the code. This constant is automatically defined by the Ruby interpreter.Print the value: To see the compiler version, you can use the
puts
method or any other appropriate output method to display the value of theRUBY_VERSION
constant. For example:
puts RUBY_VERSION
This will output the version number of the Ruby interpreter that is running the code. For instance, if you are using Ruby version 2.7.4, the output will be:
2.7.4
By following these steps, you can easily retrieve the compiler version of Ruby at runtime.
