Question

我正在尝试设置Flask网络服务器以处理SSL认证。我正在使用Windows Bash，到目前为止，该工具一直工作良好。我在linux shell中做了'''pip install pyopenssl'''并在.py shell中添加了以下行：

if __name__ == '__main__':
    app.run(debug=True, ssl_context='adhoc')

当我尝试运行flask应用程序时，我得到了：

* Serving Flask app "wss" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on https://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 437-524-983

    raise TypeError("Using ad-hoc certificates requires the pyOpenSSL library.")
TypeError: Using ad-hoc certificates requires the pyOpenSSL library.

此错误来自于serving.py文件中的Werkzeug库：

def _get_openssl_crypto_module():
    try:
        from OpenSSL import crypto
    except ImportError:
        raise TypeError("Using ad-hoc certificates requires the pyOpenSSL library.")
    else:
        return crypto

是什么原因导致此问题，以及如何解决此错误？

在Windows Bash中使用pyOpenSSL库在Flask Web应用中尝试进行SSL认证时引发TypeError
