由于业务需要将svn更新到服务器centos7上面，在安装的过程中遇到了一些问题，及解决方法。
1, 先在/etc/yum.repos.d/ 添加一个源
[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/7/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0更新源
yum clean up
yum update
当开始安装svn时报错
yum install subversion
Transaction check error:

而后在网上搜索，可能是subversion-lib 的版本太低了， 因为wandisco的源里面没有svn的lib库， 而后我使用了如下的操作，解决了问题
1.yum remove subversion
2.yum erase subversion subversion-devel subversion-libs subversion-javah
3.yum install subversion
