how do i put the path in the enviroment variables?
We could tell you the answer to this question. But you're turning into a help vampire. Look, whether or not you realize this, you can't keep running back to us everytime you don't know something. Googling something takes about 5 seconds. Reading the material you get from Google takes a bit of work.
As a programmer, you need to be able to actively solve problems, Googling, reading material, reading books, etc. as needed. Get some practice now. If we say something, and you don't understand how to do what we ask, Google first, read the material, and try it.
