macOS10.15にCocoaPodsをインストールできなかった...最後にはできたけど。
はじめに
ずいぶんと時間を無駄にしたので、メモしておく。
インストール
まず、セオリーに従ってインストールコマンドを実行。
sudo gem install -n /usr/local/bin cocoapods
エラー
実行すると以下のエラーが表示されます。
Building native extensions. This could take a while...

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.14.2/mkmf.log
extconf failed, exit code 1
Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2 for inspection.

ログを確認
詳しくは「/Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.14.2/mkmf.log」を見てね...って書いてあるので、確認してみる。
cat /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.14.2/mkmf.log
内容は以下のとおり。

調査
ログを見たところ、いくつかのファイルが見つからないようなことが書いてあり、ヘッダーファイルなどの置き場所が気になったので、それを確認しようとしてみると...
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin19
以下の結果が。
-bash: cd: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin19: No such file or directory
そんなファイルやディレクトリはないとのこと。
ファイルの一覧を見てみると...
ls -l /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/
エラーのとおり、

drwxr-xr-x 23 root wheel 736 12 4 07:52 ruby
-rw-r--r-- 1 root wheel 868 11 30 17:56 ruby.h
drwxr-xr-x 6 root wheel 192 11 30 21:27 universal-darwin20
「universal-darwin19」がない...
それならば、試しに以下のコマンドを実行し、universal-darwin19をuniversal-darwin20のシンボリックリンクとして作成。
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/
sudo ln -s universal-darwin20 universal-darwin19
再度インストールを実行
sudo gem install -n /usr/local/bin cocoapods
結果...
