yum 需要旧版本的软件包作为依赖项

Question

我已经通过官方网站安装了 TexLive 2012，并想安装依赖于旧版本的 epydoc。但是，当我尝试安装依赖于 texlive 的 epydoc 时，出现以下错误。

我怎样才能解决这个问题？

; sudo yum install epydoc

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

1. 您可以尝试使用--skip-broken来解决该问题
2. 联系 TEX-Developers 并将其报告为错误
3. 如果你真的想，你可以试试 yum downgrade

更新：因为yum --skip-broken在这里不起作用：

yumdonwloader epydoc-3.0.1-9.fc15.noarch
rpm -i --nodeps epydoc-3.0.1-9.fc15.noarch.rpm

应该管用。
