iOS-Mac上进行Fluttrt的安装

1、进入网站进行Flutter 的下载，压缩包解放存放当一个目录

2、进行将Flutter添加到路径，

vim ~/.bash_profile

点击i进行编辑，添加flutter存放的路径

export PATH=/完整的路径/flutter/bin:$PATH

点击esc-输入：wq 结束编辑

进行保存

source ~/.bash_profile

3、尝试调出Flutter help命令 查看是否成功

flutter -h

4、查看flutter 运行状态，

flutter doctor

感叹号、叉号都是不可运行的

5、iOS修复

5.1查看iOS的问题

iOS toolchain - develop for iOS devices (Xcode 10.1)
    ✗ libimobiledevice and ideviceinstaller are not installed. To install with
      Brew, run:
        brew update
        brew install --HEAD usbmuxd
        brew link usbmuxd
        brew install --HEAD libimobiledevice
        brew install ideviceinstaller
    ✗ ios-deploy not installed. To install:
        brew install ios-deploy

5.2 可以直接在终端运行，执行完下边代码执行flutter doctor,查看iOS状态并执行iOS中的提示执行的命令行

 brew update
        brew install --HEAD usbmuxd
        brew link usbmuxd
        brew install --HEAD libimobiledevice
        brew install ideviceinstaller

5.3如果不能正常运行，需要运行下面命令行

git clone https://github.com/libimobiledevice/ideviceinstaller.git
cd ideviceinstaller
./autogen.sh
make
sudo make install

5.4以上执行完毕，再次 

flutter doctor

查看iOS的状态，回到5.2进行操作
