我在MacOS上安装DMG打包的应用程序时遇到了一个奇怪的问题。以下是我所知道的，但我仍然不知道出了什么问题。
我尝试在MacOS(10.13.4(上安装skype或inkscape之类的东西
brew cask install skype --debug
但它挂起，输出如下。

所以我手动尝试了最后一行
/usr/bin/hdiutil attach -verbose -debug -plist -nobrowse -readonly -noidme -mountrandom /var/tmp/ /Users/hwwu/Library/Caches/Homebrew/Cask/skype--8.22.0.2.dmg
它悬挂并显示

brew doctor和brew cask doctor都没有表现出问题的迹象。我还禁用了LittleSnitch防火墙。我没有安装防病毒程序。安装其他DMG相关软件包都存在此问题。我已经有一段时间无法安装任何东西了。在我看来，这是一个hdiutil或系统问题，而不是任何自制错误。sudo没有帮助，它会以某种方式显示"未知 UID"。
但是，通过双击下载的DMG，它可以正常工作，并且安装就可以了。
请帮忙。
叹了口气...
事实证明，我使用的是过时的iTerms窗口，其中的用户ID已过时。 由于这个错误的 uid，hdiutil以静默方式失败。
敲钟的是sudo错误的 uid。希望读到这个问题的人不要遇到我的问题。
