这个错误通常是由于 SSL 模块未正确安装或配置导致的。你可以尝试以下步骤来解决这个问题：

1. 确认你的 Python 版本是否正确安装了 OpenSSL 支持模块。
2. 确认你的 Python 版本是否正确安装了 pip 包管理器。
3. 尝试使用非安全连接（HTTP）来安装 opencv-python 包，使用以下命令：`pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org opencv-python==4.3.0.38 --user`。
4. 如果上述方法无效，可以尝试更新 pip 版本并重新安装 opencv-python 包，使用以下命令：`python -m pip install --user --upgrade pip` 和 `pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org opencv-python==4.3.0.38 --user`。

希望这些步骤可以帮助你解决问题。
