Linux fedora安装yum以及换源
<p>下载rpm包：http://rpmfind.net/linux/rpm2html/search.php?query=yum</p><p>最近手贱，卸载了fedora下的yum，装了半天装不上去，一直报错：error: Failed dependencies</p>
<p>如何解决？</p>
<p> rpm -ivh 包名 --nodeps --force</p>

<p> </p>
<p> 加上这两个参数，就可以安装成功了。</p>
<p>加上那两个参数的意义就在于，<br>安装时不再分析包之间的依赖关系而直接安装，<br>也就不会再提示error: Failed dependencies:这样的错误了。</p>
<h2>fedora换源</h2>
<p>在使用yum install gcc命令时，报错：</p>
<p>Error: Failed to download metadata for repo 'fedora'</p>
<p>上网差了许多资料，说是要换源，但是换了之后还是不行，依旧报错。</p>
<p>终于，找到一篇文章，才解决了问题，成功运行yum install gcc。</p>
