It failed in the same way when run on one of our other testing servers. On testing the failing command, it also failed with the same message and backtrace when run manually on the server. new( 4) #=> arr.During a routine deploy (a log message was being changed) to one of our testing environment servers, the deploy failed with the message NoMethodError: undefined method gsub’ for nil:NilClass whenbundle install` was run. This method is safe to use with mutable objects such as hashes, strings or other arrays: Array. To create an array with separate objects a block can be passed instead. Therefore, it is only recommended in cases when you need to instantiate arrays with natively immutable objects such as Symbols, numbers, true or false. Note that the second argument populates the array with references to the same object. For example, the array below contains an Integer, a String and a Float: ary = #=> Īn array can also be created by explicitly calling Array.new with zero, one (the initial size of the Array) or two arguments (the initial size and a default object).

Arrays can contain different types of objects. Creating Arrays ¶ ↑Ī new array can be created by using the literal constructor. A negative index is assumed to be relative to the end of the array-that is, an index of -1 indicates the last element of the array, -2 is the next to last element in the array, and so on.

Arrays are ordered, integer-indexed collections of any object.Īrray indexing starts at 0, as in C or Java.
