M1芯片：cocoapods安装后kernel_require.rb:54:in `require‘报错

设备：MacBook2023款 M2Pro芯片

cocoapods版本：1.9.3

1. mac上安装cocoapods的相关命令

（我的电脑需要安装到1.9.3版本）

//升级cocoapods至最新版本
$ sudo gem install cocoapods -n /usr/local/bin

//升级cocoapods到指定版本  (我的电脑安装到1.9.3版本)
$ sudo gem install cocoapods -v 1.9.3

//卸载之前的旧版本
$ sudo gem uninstall cocoapods -v1.2.1

2. 安装完成后，执行`pod --version`检查是否安装成功，结果报错：

~ pod --version
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle, 0x0009): tried: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')), '/System/Volumes/Preboot/Cryptexes/OS/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (no such file), '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')) - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle (LoadError)

3. 从报错来看，需要包含arm64版本的ffi，于是执行如下命令：

$ arch -arm64 sudo gem install ffi

4. 再次执行pod命令，搞定。
