pyproject.toml: line 7: using '[tool.sip.metadata]' to specify the project metadata is deprecated and will be removed in SIP v7.0.0, use '[project]' instead

在使用Python时，当遇到"pyproject.toml: line 7: using '[tool.sip.metadata]' to specify the project metadata is deprecated and will be removed in SIP v7.0.0, use '[project]' instead"错误时，这意味着您在项目的pyproject.toml文件中使用了过时的配置方式。根据错误提示，建议您使用新的配置方式来指定项目元数据。

1、错误提示：

2、解决方法：

    1、打开项目的pyproject.toml文件，定位到第7行。

    2、将"[tool.sip.metadata]"替换为"[project]"。

    3、保存并关闭文件。

    PS：pyproject.toml 文件通常位于您的 Python 项目的根目录下。如果您无法找到 pyproject.toml 文件，可以尝试使用文件管理器或者命令行工具在项目目录中搜索这个文件。

通过使用"[project]"来指定项目元数据，您将使用最新的配置方式，以适应SIP v7.0.0及更高版本的要求。希望以上方法能够帮助您解决问题！
