cocoapodsでpodsfileが作れません。どのような事が考えられますか？

Question

xcodeでcocoapodsを用いた日記アプリを作りたいです。

他のサイトで作り方が出ているのを参考にしています。

まず、xcodeで新規プロジェクトを作りました。
次に、ターミナルでcocoapodsをインストールし、projのディレクトリまで移動しpod initを入力したところ、このようなエラーメッセージが表示されました。

Operation not permitted - getcwd (Errno::EPERM)

全体としては下記のように出ています。

どんな問題が考えられるでしょうか。

MacOSのバージョンなどを教えてください

Answer 1

おそらくcocoaPodsがうまく入っていないか、フォルダ権限の問題かと思います。

cocoaPodsの入れ直しとプロジェクトフォルダある場所などの権限を確認して下さい。

入れ直しは以下の通りです。

以下のコマンドで試してみてください。

gemのアップデート
それ以前の場合

sudo gem update --system

Mac OS Catalinaの場合

sudo gem update --system -n /usr/local/bin

cocoapodsのインストール

Mac OS Catalinaの場合

sudo gem install cocoapods -n /usr/local/bin

それ以前

sudo gem install cocoapods

Answer 2

vanderlvov様　ご回答ありがとうございました。

chownとchmodについて色々調べてみましたが、対処法がわかりませんでした。

別のサイトで記載されていた方法で一度リカバリーモードにし　$ csrutil statusを入力し
$ csrutil disableを入力したところSuccessfully disabled System Integrity Protection. Please resart the machine for the changes to take effect.と出てきて再起動したらエラーがなくなりました。

Answer 3

仮説ですが、プロジェクトフォルダの権限を確認して下さい。両方: chownとchmodで
後、Podsのフォルダは存在すれば、pod installする前に削除してみて下さい。
