启动Jupyter Notebook遇urllib3与OpenSSL版本兼容问题求助

启动Jupyter Notebook时出现如下错误：

        "urllib3 v2.0 only supports OpenSSL 1.1.1+, currently "
    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

已尝试安装的版本：

• requests==2.31.0
• urllib3==2.0.7

请问如何解决该问题？是否需要升级系统的OpenSSL？

有两种可行方案，优先推荐第一种（无需修改系统环境）：

方案1：降级urllib3到兼容版本 #

urllib3 v2.0+要求OpenSSL 1.1.1+，而当前系统是1.1.0h，直接降级urllib3到支持OpenSSL 1.1.0的版本即可：

1. 激活虚拟环境：source /Users/kevalshah/myvenv/bin/activate
2. 执行降级命令：pip install urllib3==1.26.18
3. 重新启动Jupyter Notebook：jupyter notebook

该版本的urllib3兼容OpenSSL 1.1.0，同时能和requests 2.31.0正常配合。

方案2：升级系统OpenSSL并重新编译Python（适合长期使用高版本依赖的场景） #

如果确实需要使用urllib3 v2.0+，则需要升级系统OpenSSL并重新编译Python，让Python的ssl模块链接到新的OpenSSL版本：

1. 升级系统OpenSSL到1.1.1+（macOS可通过Homebrew安装：brew install openssl@1.1）
2. 重新编译Python 3.7，编译时指定链接新安装的OpenSSL：

   ./configure --with-openssl=$(brew --prefix openssl@1.1)
   make && make install
   

3. 重新创建虚拟环境并安装依赖，再启动Jupyter Notebook
