This error originates from a subprocess, and is likely not a problem with pip.

您遇到的错误信息涉及多个方面，其中主要的问题是在尝试安装 Python 包时无法找到符合要求的版本，具体来说是安装 Cython 过程中出现问题。下面是错误的主要原因和解决方案：

1. 不信任的镜像源: 错误信息中提到，“WARNING: The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored.” 这意味着您配置的 mirrors.aliyun.com 源没有使用 HTTPS，或者没有正确设置为受信任的源。要解决这个问题，您可以：

   • 使用 HTTPS 协议的 URL 替代当前的 HTTP。
   • 如果您确认该源可信，可以在 pip 命令中添加 --trusted-host mirrors.aliyun.com。

2. 找不到匹配的包版本: “ERROR: Could not find a version that satisfies the requirement cython (from versions: none)” 这表明在指定的源中没有找到可用的 Cython 版本。解决办法可能包括：

   • 确认 mirrors.aliyun.com 是否包含 Cython 的有效版本。
   • 尝试使用其他的源，如 PyPI 官方源。

3. 配置项使用了过时的语法: 错误提示中提到了过时的“dash-separated”选项（如 index-url）应改为“underscore”形式（如 index_url）。这需要您检查和更新配置文件，确保使用正确的配置语法。

4. 使用旧的 setuptools 功能: 提示中提到 setuptools 的某些功能已过时，并建议使用 PEP 517 安装器。可以通过在 pip 安装命令中添加 --use-pep517 选项来尝试解决这个问题。

综上，您可以尝试以下步骤解决问题：

• 确认使用 HTTPS 协议的 URL 或将当前源设置为可信。
• 更新 pip 和 setuptools 到最新版本，以确保兼容性和安全性。
• 在 pip 命令中使用 --use-pep517 选项。
• 检查并更新配置文件中的过时语法。

例如，您可以尝试使用以下命令来安装 Cython：

pip install cython --trusted-host mirrors.aliyun.com --use-pep517 --index-url https://mirrors.aliyun.com/pypi/simple/

确保所有工具和配置都是最新的，并适当调整命令中的参数以适应您的具体环境。
