List of Eror Messages

I wanted to know if there is someplace where I can get a list of all
the error messages generated by Ruby as well as explanations.

The QuickRef has the list of exceptions:

I know of no list of error messages that exceptions can contain
outside of reading the source.

Not really – for a variety of reasons.

  1. Error messages come from an indefinite number of sources – from
    the Ruby interpreter itself, from built-in library classes, from
    standard library classes, from add-on libraries, etc.

  2. The majority of error messages come from classes derived from
    Exception. New Exception subclasses can derived by any developer.
    Another reason there can be no fixed list of error messages.

  3. Any Ruby code that creates a new Exception object by executing
    ‘raise’ can customize the error message of that particular exception
    object. Another source of indefinitely many error messages.

OTOH, if you are really asking “where can a list of the standard
Exception subclasses be found?”, the Pickaxe book is a good place to
look.
