python - 交互运行 pyprocessing 脚本时出现 TypeError : super(type, obj)

Question

Python 2.7.3:

创建尽可能简单的pyprocessing文件并将其另存为 foo.py:

from pyprocessing import *

def setup():
    size(100,100)

def draw():
    rect(10,10,10,10)

run()

现在在Python中:

>>> execfile('foo.py')

文件按预期运行。关闭 pyprocessing 窗口返回提示符并输入:

>>> execfile('foo.py')

迎接您的是:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "foo.py", line 9, in <module>

    super (FBOWindow, self).on_resize(w,h)
TypeError: super(type, obj): obj must be an instance or subtype of type

这里发生了什么？这是一个错误吗？我使用 pyprocessing 是否错误？

这相当于 subprocess每次都会产生一个单独的进程:

from subprocess import call 
call([sys.executable, 'foo.py'])
