我想在CentOs 6.3上安装Mercurial 2.2，但是我觉得centos的存储库有点过时，因为它的yum安装总是显示你的mercurial是最新的。在Centos上安装Mercurial 6
现在搜索一些论坛，发现了一些其他的资料库，通过使用下面的命令和存储库更新善变的客户：
**
rpm -Uvh http://pkgs.repoforge.org/mercurial/mercurial-2.2.2-1.el6.rfx.i686.rpm
**
但是它会导致以下错误：
hg = 1.4-3.el6 is needed by (installed) emacs-mercurial-1.4-3.el6.i686
hg = 1.4-3.el6 is needed by (installed) mercurial-hgk-1.4-3.el6.i686
我觉得由于一些软件包依赖，我无法安装。
任何帮助/指针将不胜感激。
我认为您需要卸载较旧的（1.4.3）版本的Mercurial。或者至少首先摆脱emacs-mercurial和mercurial-hgk软件包。
从博客：Install Mercurial Centos 6 VPS Mercurial 2.2.2 Centos 6.4 setup
This the only package you're able to install because other RPM packages require python 2.4 whereas Centos 6 has python 2.6 installed.
rpm -Uvh http://pkgs.repoforge.org/mercurial/mercurial-2.2.2-1.el6.rfx.x86_64.rpm
测试您的安装：

Mercurial Distributed SCM (version 2.2.2)
