linux完全小白一个，照着网上的步骤来的，到最后一步打包就报错了，也看不懂是什么问题，请问需要怎么解决啊？
或者能有直接安装下载下来的安装包的方法吗？

试试装base-devel

差不多这个名字

pacman -U https://mirrors.bfsu.edu.cn/archlinuxcn/x86_64/yay-11.3.2-1-x86_64.pkg.tar.zst

我记得最新版本V社好像禁掉yay 的源了，sd软件库还是用flatpak 吧

没装gcc吧

去/etc/pacman.conf添加archlinuxcn源，之后在网址下面添加
SigLevel = Optional TrustAll最后sudo pacman -Sy paru应该就可以了

居然没有stdlib.h
少见啊 gcc装了吗

缺少c语言库文件？这个试试下载gcc，但现在linux内置了rust，你可以去pacman下paru，用法和yay一样

最后两行是后加上的 ~

# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number

# - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#
# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.

其实你直接 pacman -S openssl-1.1就行了

包名都变了。。
那aur用起来很多包都会找不到...
，你自己看下wiki的PKGBUILD，把下载下来的aur的PKGBUILD中的依赖改成和steamos的仓库一样的，用makepkg自己打包安装吧。
衍生版用aur最麻烦的就是这种问题

这玩意的仓库和Arch差得太远了。除非楼主你自己去学写PKGBUILD，否则我不再推荐在这上用AUR，依赖是真的会很多找不着

yay早停更了，换paru
