Virtualenv(venv) 로 python 다른 버젼 가상환경 설정

 

 

python 3.6 버전의 패키지가 필요하다.

 

하지만 로컬 pc에 설치되어 사용중인 python은 3.9이다.

바로 venv를 실행하면, 3.9버전으로 생성이된다.

PS C:\workspace\api> python --version
Python 3.9.10
PS C:\workspace\api> mkdir setup  

    디렉터리: C:\workspace\api

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
d-----      2022-12-09   오후 1:58                setup

PS C:\workspace\api> python -m venv .venv
PS C:\workspace\api> .\.venv\Scripts\activate
(.venv) PS C:\workspace\api> python  --version
Python 3.9.10
(.venv) PS C:\workspace\api>

 

 

 

나는 3.6버전이 필요하다.

 

버전을 명시하고 venv 생성을 시도하는데,

내 pc에는 3.6이 깔려있지 않다.

PS C:\workspace\api\setup36> py -3.6 -m venv .venv
Python 3.6 not found!
Installed Pythons found by C:\WINDOWS\py.exe Launcher for Windows
 -3.9-64 *
 -3.8-64

Requested Python version (3.6) not installed, use -0 for available pythons
PS C:\workspace\api\setup36>

 

 

내 로컬 pc에 python 3.6을 설치하고,

 

버전명시 후 venv 생성을 시도한다.

성공.

PS C:\workspace\api\setup36> py -3.6 -m venv .venv
PS C:\workspace\api\setup36>  .\.venv\Scripts\activate
(.venv) PS C:\workspace\api\setup36> python --version
Python 3.6.6
(.venv) PS C:\workspace\api\setup36>

 

 

이제 venv 환경에서 필요한 python 3.6 모듈을 egg로 말아본다.
