That is because there was an explosion of possibilities with web development and a lot of different solutions where created at the same time. These days things have settled more and most technology stacks have one preferred package manager (almost always npm) and one build chain (webpack being the most popular). Yes, there have been confusion but there is a reason why and it has brought along web development that is so much better than it used to be and it is usually not very complicated these days. If you pick a stack you will usually have a cli that handles everything for you.
