已尝试无效操作 #

sudo apt-get remove python3-pip
sudo apt-get install python3-pip
sudo pip3 install pip --upgrade
sudo pip install pyopenssl --upgrade

解决方案 #

该错误源于系统pyopenssl包与底层OpenSSL库版本不兼容，或混合使用apt、pip安装包导致冲突，按以下步骤修复：

• 彻底卸载所有相关包，清理残留：

sudo apt-get purge --auto-remove python3-openssl openssl

• 更新源后重新安装系统适配版本：

sudo apt-get update
sudo apt-get install openssl python3-openssl

• 重装pip，确保使用系统包管理的兼容版本：

sudo apt-get install --reinstall python3-pip

• 验证修复：
  运行pip3 --version，无报错则问题解决。

若上述步骤无效，可通过虚拟环境隔离系统包冲突：

sudo apt-get install python3-venv
python3 -m venv myenv
source myenv/bin/activate
pip install --upgrade pip

在虚拟环境中运行目标程序即可。
