Question

我在尝试从终端启动 jupyter 笔记本时看到此错误。

    ImportError: urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'OpenSSL 1.1.0h  27 Mar 2018'. See: https://github.com/urllib3/urllib3/issues/2168

我尝试升级并安装以下版本：

requests==2.31.0

urllib3==2.0.7

如何解决这个问题？我需要升级我的系统 OpenSSL 吗？

Answer 1

urllib3 v2.0 迁移指南指出他们有

删除了对 1.1.1 之前的 OpenSSL 版本的支持。

解决问题的最佳方法是升级到 >= python 3.8，然后运行

python -m pip install urllib3

。这是因为 urllib3 的稳定版本需要：Python >=3.8。

否则，请查看上面包含的迁移指南，以找到可能解决您问题的方法。
