这个错误通常是由于SSL证书验证失败导致的。这可能是因为你的Python环境没有正确配置或更新根证书。你可以尝试更新你的Python环境中的根证书，或者使用一个不需要SSL验证的镜像源来解决这个问题。你可以使用以下命令来更换镜像源：

pip install openmim -i https://pypi.org/simple/

这将使用pypi.org作为镜像源来安装openmim。如果你需要更新根证书，你可以参考这篇文章：https://stackoverflow.com/questions/50236117/scraping-ssl-certificate-verify-failed-error-for-http-en-wikipedia-org。

这个错误通常意味着您的请求被阻止了，可能是由于 SSL 证书验证问题导致的。您可以尝试以下解决方法：

1. 确保您的网络连接正常：检查您的网络连接是否稳定，并确保可以访问互联网。

2. 更新 pip 版本：运行 `pip install --upgrade pip` 来升级到最新的 pip 版本。

3. 使用其他镜像源：尝试使用其他镜像源来替代清华大学镜像源。您可以尝试使用官方源或其他可靠的源。可以通过在命令中指定镜像源地址来进行安装，例如：

   pip install -i https://pypi.python.org/simple/ protobuf==3.12.2

4. 忽略 SSL 证书验证：如果您确定您的网络是安全的，可以尝试禁用 SSL 证书验证。运行以下命令来忽略 SSL 证书验证：

   pip install --trusted-host pypi.tuna.tsinghua.edu.cn protobuf==3.12.2

请注意，在禁用 SSL 证书验证时要小心，确保您的网络环境是安全的。

As an AI language model, I do not have the capability to troubleshoot technical issues on your device. However, this error might be caused by an outdated version of OpenSSL or an issue with the SSL certificate on the server. You can try the following solutions:

1. Upgrade OpenSSL to the latest version.
2. Check the system date and time to ensure that they are correct.
3. Try to install the package using a different internet connection.
4. Disable SSL verification by adding the following line of code before the command:

export PYTHONHTTPSVERIFY=0

Note: Disabling SSL verification can compromise the security of your system, so use this solution with caution.

If none of these solutions work, you may need to seek the help of a technical expert.
