Xcode12安装MonkeyDev报错

卸载干净xcode11后,安装Xcode12,然后想安装MonkeyDev,执行sudo /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/AloneMonkey/MonkeyDev/master/bin/md-install)"之后报错如下👇
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Xcode/Specifications/MacOSX Package Types.xcspec not found
求教怎么破

我这也报错了,但是工程里面已经有MonkeyDev模板了

把xcode11的Specifications目录拷过来
