Python 2.7 需要'packaging'包；通常这是与这个包捆绑在一起的

Question

我想这与密码模块有关，但我不确定。

Traceback (most recent call last):
  File "<string>", line 11, in <module>
  File "c:\python27\lib\site-packages\PyInstaller-2.1-py2.7.egg\PyInstaller\load
er\pyi_importers.py", line 270, in load_module

ImportError: The 'packaging' package is required; normally this is bundled with
this package so if you get this warning, consult the packager of your distributi
on.

和来源：

import os, sys, getpass, time
from cryptography.fernet import Fernet
from tqdm import tqdm
from time import gmtime, strftime
import subprocess
name = getpass.getuser()
print strftime("%Y-%m-%d %I:%M:%S")

print "-------------------------------------------------------------------------------"

   cmd='echo '+txt.strip()+'|clip'
   return subprocess.check_call(cmd, shell=True)
def delete():
    try:
        os.remove("key.txt")
        os.remove("Encryption.txt")
    except:
        print "Error, files not deleted."
def encrypt():
    input = raw_input("Please enter what you want to be encrypted: ")
    for i in tqdm(range(100)):
        time.sleep(0.01)
    key = Fernet.generate_key()
    cipher_suite = Fernet(key)
    cipher_text = cipher_suite.encrypt(input)
    plain_text = cipher_suite.decrypt(cipher_text)
    time.sleep(1)
    print "Encryption completed..."
    #save

    f = open("encryption.txt", "w")
    f.write(cipher_text)
    f.close()
    time.sleep(1)
    print "Encryption data saved to encryption.txt and copied to clipboard..."
    copy2clip(cipher_text)

    d = open("key.txt", "w")
    d.write(key + "\n\n")
    d.close()
    time.sleep(1)
    print "Key data saved to key.txt..."
    time.sleep(5)
while True:
    encrypt()
    os.system('cls')
    print strftime("%Y-%m-%d %I:%M:%S")
    print "NOTE: Encrypting will delete all data in either .txt, so please save the data."
    print "-------------------------------------------------------------------------------"

time.sleep(5)

我注意到一个名为 cryptography.hazmat.bindings._padding.pyd 的文件，我看到有人在使用它时遇到问题。我需要编辑钩子什么的吗？

Answer 1

已更新最新版本的 pyinstaller，现在可以使用了。
