Vpython localhost opens but keeps forever blank

Question

I have installed vpython from the terminal using pip install vpython , and it installed successfully. I am using python 3.10.2. When I write from vpython import * nothing happened. Then I write vp.box() or vp.sphere() .a Microsoft Edge window opens called localhost:53184 but it keeps blank forever. I tried to reinstall the package but it still not work.

I'm even tried this:

from vpython import *

box()
while True:
  pass

and it still the same

here is the package:

Answer 1

It's possible that the problem is with your infinite loop which, depending on what launcher you use, could completely lock up the browser and prevent any display. Either delete the last two lines, or change "pass" to "rate(100)".
