CocoaPods 1.2.0 にバージョンアップしたら"LoadError - cannot load such file -- nanaimo"に遭遇した話 #iOS

まあせっかくだからQiitaに書いとけ、的な？

やったこと

cocoapodsのバージョンアップ

$ sudo gem update cocoapods

リポジトリの初期化
$ pod setup

元からPodfileはあるのでpod initは省略。

$ pod install

下記のエラーに遭遇。バグ報告用のテンプレート部分は省略。

原因と対処方法

Nanaimoというgemが複数入っているとなぜかうまくロードできない。

LoadError - cannot load such file -- nanaimo · Issue #6214 · CocoaPods/CocoaPods · GitHub

対処方法としては、古いgemを消すだけ。同じgemが複数存在する場合はどれを消すか訊いてくるので、番号を入力する。

$ sudo gem uninstall nanaimo

Select gem to uninstall:
 1. nanaimo-0.2.2
 2. nanaimo-0.2.3
 3. All versions
> 1
Successfully uninstalled nanaimo-0.2.2
