如何使用 pacman 强制删除 Arch 中的软件包？

Question

我如何强制删除 Arch 中的一个包，pacman而其他包仍然依赖它。

pacman -R perl-libwww                                                               
checking dependencies...

基本上 LWP 6 拆分了一大堆软件包，我需要将其删除以便重新安装它。

您应该能够使用简单的方法重新安装软件包：

# pacman -S perl-libwww

这只会删除 perl-libwww：

# pacman -Rdd perl-libwww

请注意命令中的双-d，如果您使用--nodeps，您也必须指定两次或将其与-d组合，例如：

# pacman -R --nodeps --nodeps perl-libwww
# pacman -Rd --nodeps perl-libwww

这将删除所有依赖于 perl-libwww 的包：

# pacman -Rc perl-libwww

从 pacman 的手册页：

   -d, --nodeps
       Skips dependency version checks. Package names are still
       checked. Normally, pacman will always check a package’s
       dependency fields to ensure that all dependencies are
       installed and there are no package conflicts in the
       system. Specify this option twice to skip all dependency
       checks.
   -c, --cascade
       Remove all target packages, as well as all packages that
       depend on one or more target packages. This operation is
       recursive, and must be used with care since it can remove
       many potentially needed packages.
