What are some common Ruby errors and how can I fix them?
An example of an AI chatbot conversation about common Ruby errors and their fixes.
What are some common Ruby errors I might encounter?
Some common Ruby errors include NoMethodError, NameError, and SyntaxError. Would you like to know how to fix any specific one?
Yes, what does NoMethodError mean?
NoMethodError occurs when you try to call a method that doesn't exist for a particular object. It usually means there's a typo or you're calling a method on the wrong object.
How can I fix it?
To fix it, check the method name for typos and ensure that the object you're calling the method on is the correct type.
Can you give me an example?
Sure! If you have user.name but user is nil, you'll get a NoMethodError. Make sure user is initialized before calling methods on it.
