Python 무설치 버전

파이썬 공식 홈페이지에 무설치 버전을 제공하고 있음.
(https://www.python.org/downloads/release/python-391/)

아래로 쭉 내리다면 Windows embeddable package (64-bit) 이걸 받는다.

무설치 버전의 최고의 장점은 폴더채로 들고 다니면 어디서든 사용가능한 장점이 있음.
또 다른 응용 프로그램에 포함시켜서 파이썬의 기능을 이용할수도 있고..

어쨌든.. zip 파일을 다운받아 압축을 풀면 바로 사용가능함.
근데 문제는 pip 가 없다? pip가 없으면 외부 모듈 설치가 난감함.

pip 설치는 다음과 같이..
get-pip.py 를 아래에서 다운받아 적절한 폴더에 넣어둔다.
https://bootstrap.pypa.io/get-pip.py

다음 아래와 같이 설치한다.

C:\python-3.9.0-embed-amd64>python get-pip.py

이제 모듈을 설치할려고하니.. 이런 에러가..

C:\python-3.9.0-embed-amd64>Scripts\pip.exe install python-pptx
Traceback (most recent call last):
  File "runpy.py", line 197, in _run_module_as_main

ModuleNotFoundError: No module named 'pip'

파이썬 폴더에 보면 python39._pth 파일이 있는데 이 파일 마지막에 아래를 추가.

lib\site-packages

다시 설치하면

C:\python-3.9.0-embed-amd64>scripts\pip install python-pptx
