How do I troubleshoot environment variables in Ruby?
To troubleshoot environment variables in Ruby, you can start by checking if they are set correctly in your terminal. Use echo $VARIABLE_NAME to see their values.
What if the variable is not set?
If the variable is not set, you can define it in your terminal session using export VARIABLE_NAME=value or add it to your shell configuration file like .bashrc or .zshrc.
How can I access these variables in my Ruby code?
You can access environment variables in Ruby using ENV['VARIABLE_NAME']. This will return the value of the variable if it's set.
Is there a way to set environment variables in a Ruby script?
Yes, you can set environment variables within a Ruby script using ENV['VARIABLE_NAME'] = 'value'. This will only affect the current script's execution.
