python - Why does PyAutoGUI freeze when calling `size`? -


i'm trying test single line of pyautogui gets stuck size method called.

import pyautogui print("library imported") screenwidth, screenheight = pyautogui.size() print("measurements taken") pyautogui.moveto(screenwidth / 2, screenheight / 2) print("cursor moved")

the terminal didn't print "measurements taken" , not terminate process. found error in console log:

31/03/2015 15:57:30.000 kernel[0]: process python[2574] caught causing excessive wakeups. observed wakeups rate (per sec): 822; maximum permitted wakeups rate (per sec): 150; observation period: 300 seconds; task lifetime number of wakeups: 45377

i ran tracer see getting stuck, , apparently last line process reads is:

pyautogui/__init__.py:122   line          return platformmodule._size()

the program not go past calling platformmodule._size() in library.

my environment osx yosemite , have installed pyobjc , pyobjc-core.
