*   *  解决gem安装慢或卡住
     *  解决Failed to build gem native extension

使用Flutter打包IOS，都会有三方依赖。IOS的依赖是用CocoaPods来管理的。使用Flutter doctor会提示安装CocoaPods.

根据提示安装CocoaPods，直接安装就卡在这里一直不动了。

$sudo gem install cocoapods

在网上找到个参数，可以查看安装进度，在最后加上-V。

# 注意V是大写
    $sudo gem install cocoapods -V

看到安装过程，发现是网的问题，因为gem的源地址在国外

## 解决gem安装慢或卡住 ##

*  使用梯子直接安装。
 *  将gem的源改为国内镜像。

替换源是最简单的方法

# 替换源
    $ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
    # 查看替换后的源地址
    $ gem sources -l
    https://gems.ruby-china.com
    # 确保只有 gems.ruby-china.com

## 解决Failed to build gem native extension ##

替换gem源之后安装到最后又碰到以下问题。

Building native extensions.  This could take a while...

Google搜索发现是MacOS缺少一些头文件。因为我的是10.14。所以直接使用以下命令安装工具包。

$ open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

如果不想用命令也可以直接进入这个目录，双击安装，都会弹出安装界面。  
![macOS\_SDK\_headers\_for\_macOS\_10.14][macOS_SDK_headers_for_macOS_10.14]  
安装后，重新使用sudo gem install cocoapods就能安装成功了。

最后运行Flutter doctor,IOS显示正常。

$ flutter doctor
