If someone, reasonably-knowledgeable about the subject but reading only your post, cannot immediately determine what you did, in order to then deduce what you did wrong, then you’re probably not going to get the answer you are looking for.   For instance, exactly which package(s) did you install, and when you say that you are “not able to access this module,” which module are you talking about and exactly what (message(s)) are you seeing which cause you to conclude that “you are not able to access” it?

This site is fairly famous for providing excellent answers quickly ... but the questions have to be “answerable.”   Please read the suggested topics about “asking effectively,” and ask again (on this same thread).
