AttributeError：模块“时间”在Python 3.8中没有属性“时钟”

我已经编写了生成公共和私有密钥的代码。它在Python 3.7上运行良好，但在Python 3.8中失败。我不知道在最新版本中它怎么会失败。为我提供一些解决方案。

这是代码：

from Crypto.PublicKey import RSA


def generate_keys():
    modulus_length = 1024
    key = RSA.generate(modulus_length)
    pub_key = key.publickey()
    private_key = key.exportKey()
    public_key = pub_key.exportKey()
    return private_key, public_key


a = generate_keys()
print(a)

Python 3.8版本中的错误：

Traceback (most recent call last):
  File "temp.py", line 18, in <module>
    a = generate_keys()
  File "temp.py", line 8, in generate_keys
    key = RSA.generate(modulus_length)

    value = getRandomInteger(bits, randfunc)

    S = randfunc(N>>3)

    t = time.clock()
AttributeError: module 'time' has no attribute 'clock'

从Python 3.8 doc中：

time.clock()自Python 3.3起不推荐使用此功能，该功能已被删除：根据需要使用time.perf_counter()或time.process_time()代替，以具有明确定义的行为。（由Matthias Bussonnier在bpo-36895中贡献。）

自python 3.3 time.clock（）以来，用于生成键调用的模块已弃用的方法。

您可以降级到python 3.7或更改源代码以替换它。您也应该为此打开一个问题。

AttributeError: module 'time' has no attribute 'clock' 

据说它已弃用，这意味着仅使用具有该模块的最新版本的库。例如，根据您具有的依赖性，删除并安装

Crypto == 1.4.1，或者Mako == 1.1.2或SQLAlchemy == 1.3.6 //等等

这样做的目的是您不必降级python版本，因为以后会跟上您的进度。只需将软件包更新为与Python 3.8兼容的较新的软件包
