[macOS] macOS에 cocoapods 설치하기

cocoapods는 Xcode를 통해 맥에서 개발을 할 때 꼭 필요한, 혹은 필요성을 언젠가는 느끼게 될 라이브러리 관리 도구이다.

설치하기 위해서는, node.js가 설치되어 있어야 하며 설치 방법은 아래 포스팅을 참고하기 바란다.

그리고 간혹 바로 cocoapods이 설치가 안되는 경우가 있는데, 그 경우를 대비해서 Homebrew도 설치하기를 권한다. Homebrew는 한번쯤은 사용하게 될 패키지 관리자이며, 설치 방법은 아래 포스팅을 참고하면 된다.

💻 설치

cocoapods의 설치를 위해, terminal에 들어가준 뒤 아래의 명령어를 입력한다.

$ sudo gem install cocoapods

자신의 맥 암호를 입력해주면, 설치가 될 것이다.

그런데, 나의 경우에도 그랬고 간혹 아래와 같이 에러가 발생하며 설치가 안되는 경우가 있다.

이 경우에는, Homebrew를 사용하여 설치를 해주면 된다.

Homebrew가 설치되지 않은 사람들을 위해, 다시 한 번 설치 방법 포스팅 링크를 올린다.

macOS에 Homebrew 설치하기

Homebrew가 설치가 되었다면, 아래의 명령어를 terminal에 순서대로 입력하자.

$ brew cleanup -d -v
$ brew install cocoapods

설치가 된 후, 아래의 명령어를 통해 설치가 잘 되었음을 확인할 수 있다.

$ pod --version

📌 끝

맥에서 라이브러리 사용을 위한 준비까지 모두 끝났다.

이제 SwiftUI의 Alamofire 라이브러리를 통한 HTTP 통신 관련 포스팅을 올려볼까 한다.
