无法安装 Cocoapods，一直报错

Question

我一直在尝试安装 cocoapods，但总是出现错误。我尝试了以下命令并得到了相同的结果。

sudo gem install cocoapods    
sudo gem install -n /usr/local/bin cocoapods

构建本机扩展。这可能需要一段时间... 错误：安装 cocoapods 时出错：错误：无法构建 gem 本机扩展。

mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/include/ruby.h

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1 for inspection.

经过大量搜索，我终于找到了一个我认为可行的解决方案。如果您使用 Mac OS Catalina，则需要使用 Brew。

打开 Mac 上的终端。
现在，运行

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
使用 brew 安装 cocoapods

brew 安装 cocoapods

cocoapods 现在可以使用了！
