a normal update pod command
sudo gem install -n /usr/local/bin cocoapods
under normal circumstances, execute the above command can directly upgrade success, upgrade success everything is fine,
conversely will encounter the following upgrade failure!
➜ Ruby: sudo gem install -n /usr/local/bin cocoapods Building native extensions. This could take a while... ERROR: Error installing cocoapods: ERROR: Failed to build gem native extension. current directory: /Library/Ruby/Gems/2.3.0/gems/ffi-1.12.2/ext/ffi_c /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby -r ./siteconf20200313-24412-3logr3.rb extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/include/ruby.h extconf failed, exit code 1 Gem files will remain installed in /Library/Ruby/Gems/2.3.0/gems/ffi-1.12.2 for inspection.

this upgrade problem has been bothering for many days. Maybe there is a compatibility problem between the ruby version and the latest pod version, so ruby must be upgraded before pod can be successfully upgraded. See below :
method is found on stackoverflow, but of course there are some other exception problems to be solved during installation (by default you have xcode-select installed)
1. Install RVM p>
curl -L https://get.rvm.io | bash -s stable
if the installation is successful and the following prompts appear, you can proceed directly to step 2
Upgrade of RVM in /Users/mengshun/.rvm/ is complete. Thanks for installing RVM 🙏 Please consider donating to our open collective to help us maintain RVM. 👉 Donate: https://opencollective.com/rvm/donate
if it fails, appeared at the bottom of the error (error content curl: (7) Failed to connect to port 443 raw.githubusercontent.com: Operation timed out) p>

executes the following instruction
sudo gem install redis
then proceed with the RVM installation command (curl -L https://get.rvm.io | basket-s stable)
if error 443 is still reported, wait for a while, retries are always successful (I tried 3 times myself)
2. Install ruby 2.6
