㈠ sourceTree 过期了怎么办
sourceTree 过期了解决方法如下：
如果是单独安装的，执行如下命令：
1. sudo ln -s /Library/Developer/CommandLineTools/Library/Perl/5.16/darwin-thread-multi-2level/auto/SVN /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl/5.16.2/darwin-thread-multi-2level/auto/
2. sudo ln -s /Library/Developer/CommandLineTools/Library/Perl/5.16/darwin-thread-multi-2level/SVN /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl/5.16.2/darwin-thread-multi-2level/
如果是通过Xcode安装的，执行：
1. ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.16/darwin-thread-multi-2level/SVN /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl/5.16.2/darwin-thread-multi-2level/
2. ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.16/darw。
