我正在尝试使用命令安装 pycares
pip3 install pycares
但是产生了以下巨大的错误。
我确定在安装 pycares 之前我可能需要安装一些其他工具，但我找不到任何可以解决该问题的在线资源。
我该怎么办？请帮忙。

我需要 pycares，因为我想在我的 ubuntu 机器上运行 theHarvester。 但是在我从 github git clone theHarvester 存储库并运行 pip install -r requirements.txt 命令之后，除了 pycares 再次生成了这个巨大的错误之外，每个库都被安装了。

您需要 Python 开发文件。
sudo apt install python3-dev
