python - 如何修复树莓派中的 IOError？

Question

Traceback (most recent call last):
  File "RoomCheck.py", line 4, in <module>
    from grove_rgb_lcd import *
  File "build/bdist.linux-armv7l/egg/grove_rgb_lcd.py", line 33, in <module>
...skip

会生成这些错误。

我还附上了错误捕获：

代码：

from flask import Flask
from flask import render_template
from grovepi import *
from grove_rgb_lcd import *
