[Python] 파이썬 BeautifulSoup 설치 오류시 해결 방법 : os.system(), pip install beautifulsoup4

import 문에 빨간줄이 표시가되어 마우스를 올렸다.

BeautifulSoup 모듈을 사용하기위해서는 패키지를 설치해야한다.  클릭하여 자동설치를 시작하였으나 바로 오류가 터졌다.

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at

You should consider upgrading via the 'C:UsersilikeAppDataLocalProgramsPythonPython39python.exe -m pip install --upgrade pip' command.

[해결방법] 명령프롬프트(cmd) 창을 열고  pip 업그레이드 명령을 쳐서 업그레이드를 먼저 진행했다.

하지만 안타깝게도 파이썬3에서는 BeautifulSoup-3.2.2.버전을 사용할 수 없다. BeautifulSoup 4를 사용해야한다. 

설치방법은 터미널창을 열거나 명령프롬프트를 열고 pip install beautifulsoup4 명령어를 실행하면 된다.

또다른 설치 방법은 os모듈을 import 후 os.system()함수를 사용하여 명령어를 실행할 수 있다.

>>> import os
>>> os.system("pip install beautifulsoup4")

Requirement already satisfied: soupsieve>1.2 in c:usersilikeappdatalocalprogramspythonpython39libsite-packages (from beautifulsoup4) (2.0.1)

마지막으로 import 해야하는 모듈이 변경되었다.


import requests, BeautifulSoup


from bs4 import BeautifulSoup
