报错: xcrun: error: unable to find utility "PackageApplication", not a developer tool or in PATH
先去找个旧版的Xcode里面copy一份过来
放到下面这个目录:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/
然后执行命令
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/
chmod +x /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/PackageApplication
