No module named pytube found

So I've already seen that I need to do something like pip install pytube and ive already done that but when I run my code, I see a "no module named "Pytube" found" error. When I use pip install pytube in my terminal, it says that the installation was complete, but I still am getting the error. Idk if this is a dumb mistake or something deeper but any help would be appreciated.
