sourceTree 更新svn提示can't locate SVN/Core.pm

装了sourceTree一直没有怎么用,今天试着用用,竟然报错 can't locate SVN/Core.pm

详细报错以下:

Can't locate SVN/Core.pm in @INC (you may need to install the SVN::Core module) (@INC contains: 
/usr/local/git/lib/perl5/site_perl /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.2 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl/Git/SVN/Editor.pm line 5.

网上找到解决办法

 sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN /System/Library/Perl/Extras/5.18/SVN
 sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/auto/SVN/ /System/Library/Perl/Extras/5.18/auto/SVN

可是运行发现提示错误

ln: /System/Library/Perl/Extras/5.18/SVN: Operation not permitted

最后在一个国外的网友分享下找到了解决办法

sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN/ /Library/Perl/5.18/SVN
sudo mkdir /Library/Perl/5.18/auto
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/auto/SVN/ /Library/Perl/5.18/auto/SVN

完美运行了
