[!] Oh no, an error occurred.

... 省略 。。。

解決策:
Step 1
ターミナル(Terminal)アプリをFinderでアプリケーションディレクトリー上探します。
右クリックして、情報を見るを開きます。
「Rosettaを使用して開く」にクリックしておきます。

Step 2
ターミナルを再度開いて、以下のコメントを実施します。

sudo gem install ffi

もし、既存ffiがインストールされた場合、先に

sudo gem uninstall ffi 

を実施して、再インストールしてます。

Step 3
次に、ターミナルでPodをインストールします。

pod install

以下のように無事コンパイルされた!

Generating Pods project
Integrating client project
Pod installation complete! There are 26 dependencies from the Podfile and 47 total pods installed.

蛇の足ですが、場合によって、Macを再起動しないとコンパイルに通らないようです。
