我得到的错误与-〉The library libcrypto could not be found中提到的错误完全相同
我理解了这个问题，但是我不能找到解决方案。我需要更新我的lambda配置还是我需要升级我的Python库？

尝试使用上面的Dockerfile执行docker build会导致失败，错误如下：

异常发生在https://github.com/wbond/oscrypto/blob/1.3.0/oscrypto/_openssl/_libcrypto_cffi.py
通过跟踪oscrypto._ffi，问题归结为使用ctypes库打开libcrypto的问题：

>>> import ctypes.util
>>> ctypes.util.find_library('crypto')
>>>

为什么？因为/usr/lib只有libcrypto.so.1.1，而没有指向它的libcrypto.so符号链接。只需在您的Dockerfile中添加一行即可轻松修复：

RUN ln -s libcrypto.so.1.1 /usr/lib/libcrypto.so

......之后Python的ctypes行为：

>>> from ctypes.util import find_library
>>> find_library('crypto')
'libcrypto.so.1.1'

......奥斯卡也是：

>>> from oscrypto import asymmetric
>>>

使用基于Alpine的Docker映像中的oscrypto库未找到libcrypto
