Question

我无法从pynput库中导入某些内容。

在我的代码中，我想使用python库（pynput）在鼠标和键盘上执行一些操作。当我仅导入键盘或鼠标时，它可以工作，但是有时同时导入两者时，则会给我一些错误。

这是我的代码：

from pynput.mouse import Button, Controller
from pynput.keyboard import Key, Controller

from time import sleep

mouse = Controller()
keyboard = Controller()
rock1x = 691
rock1y = 466
rock2x = 548
rock2y = 350
rock3x = 687
rock3y = 234

while (1):
    drop1x = 1183
    drop1y = 325
    drop2x = 1220
    drop2y = 325
    drop3x = 1263
    drop3y = 325
    drop4x = 1303
    drop4y = 325

    for i in range(8):
        sleep(2.5)
        mouse.position = (rock2x,rock2y)
        sleep(0.3)
        mouse.press(Button.left)
        mouse.release(Button.left)
        sleep(2.1)

        mouse.position = (rock3x,rock3y)
        sleep(0.3)

        mouse.press(Button.left)
        mouse.release(Button.left)
        sleep(2.1)

        mouse.position = (rock1x,rock1y)

        sleep(0.2)
        mouse.press(Button.left)
        mouse.release(Button.left)

    for i in range(3):
        keyboard.press(Key.shift)
        for x in range(6):
            mouse.position = (drop1x,drop1y)
            sleep(0.3)
            mouse.press(Button.left)
            mouse.release(Button.left) 
            drop1y=drop1y+35
        for x in range(6):
            mouse.position = (drop2x,drop2y)
            sleep(0.3)
            mouse.press(Button.left)
            mouse.release(Button.left) 
            drop2y=drop2y+35
        for x in range(6):
            mouse.position = (drop3x,drop3y)
            sleep(0.3)
            mouse.press(Button.left)
            mouse.release(Button.left) 
            drop3y=drop3y+35
        for x in range(6):
            mouse.position = (drop4x,drop4y)
            sleep(0.3)
            mouse.press(Button.left)
            mouse.release(Button.left) 
            drop4y=drop4y+35
        keyboard.release(Key.shift)
    sleep(3)

运行此代码时，出现以下错误：

Traceback (most recent call last):
  File "mining.py", line 29, in <module>
    mouse.press(Button.left)
  File "/home/filipe/.local/lib/python2.7/site-packages/pynput/keyboard/_base.py", line 366, in press
    if resolved.is_dead:
AttributeError: 'NoneType' object has no attribute 'is_dead'

但是当我评论第二行时：

from pynput.keyboard import Key, Controller

代码将一直运行到：

keyboard.press(Key.shift)

并给我错误：

Traceback (most recent call last):
  File "mining.py", line 48, in <module>
    keyboard.press(Key.shift)
NameError: name 'Key' is not defined

我应该如何从pynput库导入以使用鼠标和键盘？

Answer 1

我认为问题在于您要导入两个不同的Controller。

第二个（pynput.keyboard.Controller）覆盖第一个，因为它是最后一个定义的。因此，变量mouse实际上是pynput.keyboard.Controller对象，而不是您期望的pynput.mouse.Controller对象。

当您调用mouse.press(Button.left)时发生错误，因为Keyboard对象试图按Button，而它不能这样做（只能按Key s）。

要解决此问题，请使用import/as“一般”导入模块，而不要使用from/import导入模块的“特定”部分：

import pynput.mouse    as ms
import pynput.keyboard as kb

这样，您可以区分两个控制器：

mouse    = ms.Controller()
keyboard = kb.Controller()

希望这会有所帮助-请提供任何反馈意见！
