我最近了解了 Python 运行压缩目录的能力，并开始尝试它。这对于我测试过的小型纯 Python 程序非常有效。但是，一旦我使用基于 C 的库迁移到更大的应用程序，事情就会变得如此。我有一个使用密码学的应用程序，但我无法让它工作。以下是如何产生我看到的错误：

这是__main__文件：

# cat __main__.py 
import os
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes
from cryptography.hazmat.backends import default_backend
backend = default_backend()
key = os.urandom(32)
iv = os.urandom(16)
cipher = Cipher(algorithms.AES(key), modes.CBC(iv), backend=backend)
encryptor = cipher.encryptor()
ct = encryptor.update(b"a secret message") + encryptor.finalize()
decryptor = cipher.decryptor()
print(decryptor.update(ct) + decryptor.finalize())

这是创建压缩文件的方法：

#!/bin/bash
set -e
rm -R build/
mkdir build
cp __main__.py build/
pip2 install -v -U --no-cache-dir --target=build/ cryptography
cd build/
zip -r ../test.pyz .

现在我得到了一个test.pyz我正在尝试运行的文件，但出现以下错误：

$ python2 test.pyz
Traceback (most recent call last):
  File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

  File "/tmp/tmpZjvIXl/lib/python/cryptography/hazmat/primitives/constant_time.py", line 9, in <module>
ImportError: No module named _constant_time

有谁知道如何在 zip 文件中使用基于 C 的模块？

更新

正如建议的那样，我尝试使用 zipapp 打包应用程序并使用 Python3 运行它，但我仍然看到同样的错误。

这是我失败的完整日志：

$ pip3.5 install -v -U --no-cache-dir --target=build/ pycryptodome

    print(bla)

不知道如何在压缩目录中使用基于 C 的模块...
