问题解决

1. Android licenses全部接受

flutter doctor --android-licenses

# 然后一路 y 就可以了

2. 如果提示没有安装 cocoapods

### 方式一（推荐，版本是1.10.0以上的版本）
# 安装
brew install cocoapods
# 卸载
brew uninstall cocoapods
# link
# 根据提示进行强制link就可以了，具体的那个命令忘了，但是这个步骤是必须的！！！
brew link cocoapods

### 方式二
# 安装
sudo gem install cocoapods （这个命令我会报错，ruby有问题）
sudo gem install cocoapods -v 1.8.4 （这个健康检测会提示版本较低）
# 卸载
sudo gem uninstall cocoapods

完美状态
