我最近安装了 antergos，并在尝试通过 pacaur 或 yaourt（包括包管理器）安装任何包时发现此错误。在 64 位操作系统上使用 Arch linux、antergos 发行版。关于它可能是什么的任何提示吗？
pacaurt -S i3-gaps-next-git
warning: failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"

用户建议运行以下命令： XML_CATALOG_FILES="/usr/local/etc/xml/catalog" yaourt -S i3-gaps-next-git 导致不同的错误：
xmlto: /tmp/yaourt-tmp-cesard11/aur-i3-gaps-next-git/src/i3/build/man/i3.xml does not validate (status 3)

答案1
我最近也遇到了这个。
按照 arch wiki 上的说明进行操作：https://wiki.archlinux.org/index.php/Docbook#Compilation_errors
我运行了pacman -S docbook-xml docbook-xsl它而没有--needed重新安装软件包。
之后，我就能够成功构建了。
