Xcode升级到8.3后 用命令进行打包 提示下面这个错误
xcrun: error: unable to find utility "PackageApplication", not a developer tool or in PATH
后面根据对比发现新版的Xcode少了这个PackageApplication
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
最后附上PackageApplication下载地址：
