FileNotFoundError while using PuLP in Python

I am trying to solve Linear Programing Problem through PuLP in pyhthon. I have declared the problem (by name prob) without any error:

MAXIMIZE
20*x1 + 30*x2 + 0
SUBJECT TO
_C1: x1 + 2 x2 <= 100

_C2: 2 x1 + x2 <= 100

VARIABLES
x1 Continuous
x2 Continuous 

But now when I try to solve it, it is giving me an error

Here is what I typed:

prob.solve()

And here is the error I am getting
