git svn 错误 Can't locate SVN/Core.pm 的解决方案

【错误场景】

组里面要把代码从svn服务器里整体迁移到git上，准备两步走。
第一步，用 git svn转换成git仓库，
第二步，把git仓库提交到git服务器上。
本来是很快乐的事情，然而勇者在买装备的时候遇到了麻烦，在git svn的时候出错了。魔王只能再等我一会了。

操作系统：

[counsellor@localhost git]$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)

git版本：

[counsellor@localhost git]$ git --version
git version 2.12.0

svn版本：

[counsellor@localhost git]$ svn --version
svn, version 1.9.4 (r1740329)
   compiled Jul 14 2016, 12:41:14 on x86_64-redhat-linux-gnu

perl版本：

[counsellor@localhost git]$ perl --version

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 29 registered patches, see perl -V for more detail)

【解决方案】

yum install subversion-perl

【问题分析】

先找到报错的第一现场：

/usr/local/share/perl5/Git/SVN/Utils.pm line 6

看代码：

package Git::SVN::Utils;

use strict; 
use warnings;

use SVN::Core;

可以看到是use SVN::Core;调用svn模块时，perl代码提示找不到svn模块。所以说明perl里没有svn相关的库，安装即可。
