上周更新了10.14版本后，发现IDEA内的svn无法正常使用，后续在终端中查看svn版本，得到以下错误提示：
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Mac的svn是自带的，所以立即考虑去Apple Developer下载相应版本的工具即可：
Command_Line_Tools_macOS_10.14_for_Xcode_10.dmg

安装后svn已经可以正常使用
