pyinstaller 出现OSError:Cannot loa

使用阿里云储存对象OSS的SDK工具上传图片到阿里云bucket里面，用Pyinstaller打包后，运行出错，提示：

Hook for PyCryptodome library: https://pypi.python.org/pypi/pycryptodome

PyCryptodome is an almost drop-in replacement for the now unmaintained
PyCrypto library. The two are mutually exclusive as they live under
the same package ("Crypto").

PyCryptodome distributes dynamic libraries and builds them as if they were
Python C extensions (even though they are not extensions - as they can't be
imported by Python). It might sound a bit weird, but this decision is rooted
in PyPy and its partial and slow support for C extensions. However, this also
invalidates several of the existing methods used by PyInstaller to decide the
right files to pull in.

Even though this hook is meant to help with PyCryptodome only, it will be
triggered also when PyCrypto is installed, so it must be tested with both.

Tested with PyCryptodome 3.5.1, PyCrypto 2.6.1, Python 2.7 & 3.6, Fedora & Windows

# Include the modules as binaries in a subfolder named like the package.
# Cryptodome's loader expects to find them inside the package directory for

博主优化后的是：

import glob

from PyInstaller.compat import EXTENSION_SUFFIXES
from PyInstaller.utils.hooks import get_module_file_attribute

binaries = []
binary_module_names = [
    'Crypto.Math',      # First in the list
    'Crypto.Cipher',
    'Crypto.Util',
    'Crypto.Hash',
    'Crypto.Protocol',
]

try:
    for module_name in binary_module_names:
        m_dir = os.path.dirname(get_module_file_attribute(module_name))
        for ext in EXTENSION_SUFFIXES:
            module_bin = glob.glob(os.path.join(m_dir, '_*%s' % ext))
            for f in module_bin:
                binaries.append((f, module_name.replace('.', os.sep)))
except ImportError:
    # Do nothing for PyCrypto (Crypto.Math does not exist there)
    pass

保存到 C:\python27\Lib\site-packages\PyInstaller\hooks，文件名是hook-Crypto.py,之后关键的是要重启CMD控制端，如果之前有打包过的，把pyinstaller的build里面的该打包程序的文件夹删除，还有spec的一起删除，重新打包就可以
