我想编译一个 c 文件，但输入编译命令后发生错误。
~$ gcc helloworld.c -o helloworld
fatal error: stdio.h: No such file or directory
compilation terminated.
我根据互联网上的方法安装了libc6-dev
~$ sudo apt install libc6-dev
然后出现了这个错误

我该怎么办
我有 debian，但我认为这个解决方案可以帮助你。这是我添加到我的/etc/apt/sources.list 的新行
deb http://ftp.it.debian.org/debian bullseye-updates main contrib non-free
您可以尝试安装特定版本的libc6
sudo apt update
sudo apt upgrade
sudo apt install libc6=2.35-0ubuntu3
