我想在当前的ArchLinux上降级我的gcc。

当我尝试通过gcc安装时 yaourt --noconfirm - 需要gcc48
有人知道它为什么不起作用。这些错误无论如何都无济于事......

在arch linux上可以使用shell命令：
降级gcc
答案 1 :(得分：2)
cd /var/cache/pacman/pkg/
pacman -U <file_name_of_the_package>
当然，你必须拥有你想要的版本。

"downgrade gcc"
你确定你使用的是Archlinux吗？
答案 2 :(得分：1)
您应指定gcc和gcc-libs。例如，如果您要将7.1.1降级为6.3.1：
方法1）
pacman -U /var/cache/pacman/pkg/gcc-6.3.1-2-x86_64.pkg.tar.xz /var/cache/pacman/pkg/gcc-libs-6.3.1-2-x86_64.pkg.tar.xz
方法2）
downgrade gcc gcc-libs
选择想要的版本。
