我已经通过官方网站安装了TexLive 2012，并且想安装依赖于旧版本的epydoc。但是，当我尝试安装依赖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
--skip-broken解决此问题yum downgrade更新：由于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。
