最近有同學(xué)反應(yīng)不能為flutter正確配置iOS開發(fā)環(huán)境靶擦，當(dāng)執(zhí)行brew install --HEAD libimobiledevice時會遇到一個問題：
brew install --HEAD libimobiledevice
==> Cloning [https://git.libimobiledevice.org/libimobiledevice.git](https://git.libimobiledevice.org/libimobiledevice.git) Updating /Users/rjoiner/Library/Caches/Homebrew/libimobiledevice--git
==> Checking out branch master Already on 'master' Your branch is up to date with 'origin/master'. HEAD is now at b34e343 tools: Remove length check on device UDID arguments to support newer devices
==> ./autogen.sh Last 15 lines from /Users/rjoiner/Library/Logs/Homebrew/libimobiledevice/01.autogen.sh: checking dynamic linker characteristics... darwin16.7.0 dyld checking how to hardcode library paths into programs... immediate checking for pkg-config... /usr/local/opt/pkg-config/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes checking for libusbmuxd >= 1.1.0... no configure: error: Package requirements (libusbmuxd >= 1.1.0) were not met:
Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10
簡直是黑人問號啊腮考，輸出這么一大堆信息。但我們仔細(xì)看最后一行玄捕，我們會發(fā)現(xiàn)異常所在Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10踩蔚，很顯然是由于系統(tǒng)要求的*libusbmuxd *版本和所要安裝的版本不一致。
經(jīng)過一番搜索終于找到了問題所在:
A recent change to
libimobiledevicebumped the constraint on libusbmuxd to >= version 1.1.0. The currentusbmuxdhomebrew package is version 1.0.10.
As a result, homebrew--HEADinstalls of libimobiledevice no longer build without a--HEADinstall ofusbmuxd.
Until theusbmuxdhomebrew formula is updated, a workaround is to install it at HEAD:
總之就是libimobiledevice更新了桩盲，我們可以通過下面的方式安裝libimobiledevice:
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
