安装cocoapods

1、安装Ruby

mac电脑，不要使用系统自带的Ruby(系统自带版本不可升级 )，因为版本旧、违反系统安全

另外，未来苹果会不再内置Ruby

1. Install Ruby with brew install ruby.

2. Update $PATH settings in the ~/.zshrc file.

   执行完brew install ruby后，terminal（终端）会显示下面一段话：

   If you need to have ruby first in your PATH, run:

   echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

   根据提示将PATH添加到zshrc就可以了。

$ open -e ~/.zshrc
然后在打开的.zshrc文件中添加
export PATH="/usr/local/opt/ruby/bin:$PATH"'
保存文件后，执行
$ source ~/.zshrc
最后验证一下
ruby -v

2、安装CocoaPods

CocoaPods官网也不建议使用系统自带的Ruby，建议使用更新版本的Ruby。

Which Ruby?

MacOS comes with a "system Ruby" pre-installed.

Use the which command to see where Ruby is installed:

$ which ruby
/usr/bin/ruby

If you see /usr/bin/ruby, it is the pre-installed macOS system Ruby.

Some developers use the system Ruby for running sysadmin scripts. That's fine, as long as you don't alter the system Ruby by attempting to update or add gems.

For developing projects with Ruby, you should Install Ruby with Homebrew or use a version manager such as asdf, chruby, rbenv, or rvm. A version manager helps if you're juggling multiple projects and can't update all at once. For a guide that compares version managers and shows the best way to install Ruby, see Install Ruby on a Mac.

Why using the macOS system Ruby is bad

Let's take a look at the reasons why it's a bad idea to use the Mac default Ruby for development.

1. Gem installation problems
2. Don't violate system security
3. Gem management
4. The Mac's old Ruby

Future versions of macOS

Apple says:

"Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won't include scripting language runtimes by default, and might require you to install additional packages."

In future versions, the system Ruby may already be gone (or hidden from you). In that case, you'll need to install Ruby with Homebrew or use a version manager.

CocoaPods Installation

CocoaPods is built with Ruby and it will be installable with the default Ruby available on macOS. However, we recommend not using the system provided Ruby and instead installing a newer Ruby version separate from the system installation. You can use a Ruby Version manager such as RVM or rbenv to manage multiple Ruby versions, or you can use Homebrew to install a newer Ruby with brew install ruby.
