私は多くのことを探していると私はこれらのエラーについては何も見つけることができません。

どうすれば解決できますか？

Answer 1

JSON 1.8.3 is not compatible with ruby 2.4.と思われます。彼らは今それを修正していると思います。それと同時に、私は同じ問題をRubyにダウングレードすることで解決しました。2.3

Answer 2

私は同じ問題を抱えていました。私は自分のサイトからCocoapodsアプリをインストールしました。これにより、私は自分のアプリに必要なココアポッドを作成できました（ファイアベースの統合）。コマンドラインツールをインストールする

https://github.com/CocoaPods/CocoaPods/issues/6299#issuecomment-269282062

は私のために働くように見えたが、これは正しく構築されるようにうまくいけば、壊れた依存関係（json1.8.3）が固定されます。

より永続的な解決策が見つかるまで、これが役立つことを望みます。

Answer 3
