Question

在python-binance软件包中导入时，尝试运行包含OpenSSL和cryptography模块的Python 3代码失败。这是错误的部分堆栈跟踪：

  File "/usr/lib/python3/dist-packages/cryptography/x509/base.py", line 15, in <module>
    from cryptography.x509.extensions import Extension, ExtensionType
  File "/usr/lib/python3/dist-packages/cryptography/x509/extensions.py", line 19, in <module>
    from cryptography.hazmat.primitives import constant_time, serialization
  File "/usr/lib/python3/dist-packages/cryptography/hazmat/primitives/constant_time.py", line 9, in <module>
    from cryptography.hazmat.bindings._constant_time import lib
ModuleNotFoundError: No module named 'cryptography.hazmat.bindings._constant_time'

对我来说，解决方案是升级加密软件包：

pip3 install --upgrade cryptography

我还验证了所需系统软件包的安装：

sudo apt install build-essential libssl-dev libffi-dev python3-dev

密码包导入失败
