Also facing this issue.

The unary + method was added in ruby 2.3.0.

https://docs.ruby-lang.org/en/2.3.0/String.html#method-i-2B-40

The string literal changes introduced in #711 make httparty compatible with ruby 2.3+.

@lacostej thanks! I didn't even notice that little change sneak in. Would "".dup fix that and work fine with 2.0.0?
