如何修复 gcc 导入错误问题

我有一个 ubuntu 19，我试图将我的 gcc 版本从 7.8 更改为 4.8.5（我猜）。在我尝试使用此命令后

link in ${@:1}; do sudo ln -s -f "/usr/bin/${link}-${0}" "/usr/bin/${link}"; done' 4.8

如何选择默认的gcc和g++版本？

在我尝试使用 gcc -v 或 gcc --version 甚至尝试使用 gcc 编译任何东西后，我得到了错误

Original exception was:

我该怎么做才能解决这个问题并获得新版本的 gcc 4.8

我建议您重新安装，只保留您需要/想要的 gcc 版本。卸载所有 g++ 和 gcc，然后重新安装。如有必要，请清除它们。
