python quits unexpectedly running pyautogui

Question

I'm running Python 2.7.12 installed with homebrew on my Mac OS X 10.11 and trying to use pyautogui. However, it keeps crashing ("Python quit unexpectedly.") when I try to run it as an imported module in another .py file. Like this:

    # gui.py

    import pyautogui

    def myfunction():
        pyautogui.click( 100 , 200 )

    if __name__ == '__main__':
        myfunction()


    # another.py

    import gui

    gui.myfunction()

It works fine when I run "python gui.py" alone. But when I try to run another.py, even without calling any function from gui.py, Python would crash every single time. After narrowing it down with line by line elimination, it seems it's the

    import pyautogui

that caused the crash. Any idea why? All I know is when included as a module, a .pyc file is created. I tried to delete it and run again, but didn't do anything.

Thank you!

I got it! This is because I'm importing pyscreenshot, and there is a conflict between it and pyautogui. Both use pillow and probably have some different reference to it that I'm not knowledgeable enough to tell. But as soon as I removed the pyscreenshot, pyautogui is running normal.
