  • 解决方法：

    1
    2
    pip uninstall -y certifi
    pip install certifi

  • 推测可能是本地证书过期了，所以ssl验证失败导致的；

  • 深挖一下发现certifi库也是requests项目组维护的，并且从requests项目中独立出来了，原文如下：
    Certifi CA Bundle
    Certifi is a carefully curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. It has been extracted from the Requests project.原文链接
