问题 I am extremely new to ruby as well as gem making. I made a simple gem that webscrapes some information depending on the input. However, to use my gem I need to go into the interpreter (irb) and require my gem and then call the method with some parameters. Suppose the gem is called foo .

Thanks in advance!
