这是有人问我的一个问题，当时她给的报错信息是：

Exception ignored in: <bound method TextStim.__del__ of <psychopy.visual.text.TextStim object at 0x15F76A50>>
Traceback (most recent call last):
  File "D:\PsychoPy3\lib\site-packages\psychopy\visual\text.py", line 220, in __del__
  File "D:\PsychoPy3\lib\site-packages\pyglet\gl\lib.py", line 97, in errcheck
TypeError: 'NoneType' object is not callable

我自己安装完 Psychopy3 之后得到的报错如下：

Exception ignored in: <bound method TextStim.__del__ of <psychopy.visual.text.TextStim object at 0x00000000194C4908>>
Traceback (most recent call last):
  File "D:\lx\Anaconda\envs\psypy3\lib\site-packages\psychopy\visual\text.py", line 220, in __del__
  File "D:\lx\Anaconda\envs\psypy3\lib\site-packages\pyglet\gl\lib.py", line 97, in errcheck
ModuleNotFoundError: import of pyglet halted; None in sys.modules

原来 import 库的顺序如下：

from psychopy import event, visual, gui, core

在 GitHub 上找到了解决办法，把 visual 和 event 导入顺序调换一下，即：

from psychopy import visual, event, gui, core

还有一种解决办法就是手动删除对象：

del xxx
