conda create -n example

  : example이라는 이름의 가상환경을 만듦
  : -n 대신 --name이라고 써도 됨
  : 비어있는 가상환경이 만들어지며, 아무것도 - 파이썬도 - 설치되지 않음

 

conda create -n example python

  : 가상환경 만들면서 파이썬도 같이 설치
  : 파이썬 외에도 pip, tk, sqlite 포함해서 10여 가지가 자동으로 설치됨
  : 아래는 2024년 8월 20일 기준, python 설치 시 같이 설치되는 패키지 목록임

conda create -n example python=3.12.0

  : 가상환경 만들면서 파이썬도 같이 설치하되, 파이썬 버전은 3.12.0으로 함

conda search <package_name>

  : 설치 가능한 패키지 버전을 보여줌
  : python, numpy, matplotlib 등 패키지 이름을 넣으면 됨
  : conda create로 가상환경 만들 때 패키지의 버전을 선택하지 않으면 최신 버전으로 설치

conda create -n example python numpy

  : 가상환경 만들면서 파이썬과 넘파이도 같이 설치

conda activate example

  : example이라는 이름의 가상환경을 활성화 함
  : 프롬프트가 (example)로 시작하도록 바뀜

conda list

  : 현재 가상환경에 설치된 패키지 목록을 보여줌

conda install <package_name>

  : 현재 가상환경에 패키지를 설치
  : 상기한 방법대로 버전을 지정할 수 있음

conda install <package_name> -y

  : Proceed ([y]/n)?을 스킵

conda update <package_name>

  : 패키지 업데이트

conda remove <package_name>

  : 현재 가상환경에서 패키지 삭제
  : conda uninstall이라고 써도 됨 (둘은 서로의 alias임)
  : 이때 삭제할 패키지에 depend 하는 패키지도 같이 삭제됨

 

conda info

  : 현재 가상환경의 정보를 보여줌

conda env list

  : 만들어져 있는 가상환경들을 보여줌

conda list -n example

  : example 가상환경에 설치되어 있는 패키지 목록을 보여줌

conda install -n example <package_name>

  : example 가상환경에 패키지 설치
  

conda remove -n example <package_name>

  : example 가상환경에서 패키지 삭제

conda remove -n example --all

  : example 가상환경을 삭제함

conda create --clone example -n example2

  : example을 복제해서 example2를 만듦

conda <command> -h

  : command의 도움말 보여줌
  : -h 대신 --help라고 써도 됨

위에서 만든 가상환경을 vscode에서 사용하는 방법
  : ctrl + shift + p
  : Python: Select intepreter 선택
  : 목록에서 선택하거나, 없으면 Enter interpreter path...를 눌러서 path 지정
  : 활성화된 가상환경은 창 우하단에 ('<env_name>': conda)로 표시됨
