解决 ：
To update with Brew, run:
brew update
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies usbmuxd
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
问题2
安装 ，brew install --HEAD usbmuxd
./configure: line 16735: syntax error near unexpected token `libplist,'
./configure: line 16735: `PKG_CHECK_MODULES(libplist, libplist >= $LIBPLIST_VERSION)'
在 https://github.com/flutter/flutter/issues/24716 中找到解决方法：
I solved it running
brew doctor
And resolving this warning:
Warning: You have unlinked kegs in your Cellar
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
pkg-config
libtool
libksba
python@2
libyaml
libgpg-error
依次执行：
brew link pkg-config
。。。。
在执行 剩下的命令：
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
运行 flutter doctor
结果：
