上文：iOS flutter研究（一）- 安裝

flutter_app打開(kāi)后，找不到設(shè)備（模擬器、真機(jī)）

一、配置環(huán)境變量

$ export PATH=$PATH:/Library/flutter/bin

二、運(yùn)行run flutter doctor

$ flutter doctor

運(yùn)行結(jié)果：

        CocoaPods is used to retrieve the iOS platform side's plugin code that
        responds to your plugin usage on the Dart side.
        Without resolving iOS dependencies with CocoaPods, plugins will not work
        on iOS.
        For more info, see https://flutter.io/platform-plugins
      To upgrade:
        brew upgrade cocoapods
        pod setup

三、問(wèn)題解決

從運(yùn)行結(jié)果可以看出有[!]標(biāo)識(shí)的都是有問(wèn)題的選項(xiàng)。
1、更新command-line

2、執(zhí)行以下命令

 $ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

3、查看Android Studio工具，現(xiàn)在已經(jīng)可以找到iPhone模擬器了，使用模擬器已經(jīng)可以正常運(yùn)行
4、安裝homebrew
5、確保homebrew是最新版本

 $ brew update

6、執(zhí)行以下命令

 $ brew install --HEAD usbmuxd

 $ brew link usbmuxd

 $ brew install --HEAD libimobiledevice

 $ brew install ideviceinstaller ios-deploy cocoapods

 $ pod setup

7、打開(kāi)Android Studio設(shè)備切換為真機(jī)，運(yùn)行成功
