我很感谢任何建议。
那是我的python脚本：
from pynput.mouse import Button, Controller
import time
time = time.localtime()
hourMinSec = (str(time.tm_hour) +":"+ str(time.tm_min) +":"+ str(time.tm_sec))
mouse = Controller()
print (mouse.position)
print (hourMinSec)
with open('/home/panda/desktop/mouseProg.log', 'a') as f:
f.write(str(mouse.position) + "\n")
f.write(str(hourMinSec) + "\n")
这显然给了我鼠标的位置和时间。
（1234,234）

在linux终端中运行得很好。
但是当我尝试通过crontab运行它时，我得到了：

问题似乎与
有关from pynput.mouse import Button, Controller
当我注释掉它（以及相关行）时，它甚至可以通过crontab正常运行。
