[파이썬] pip install beautifulsoup4 설치시 오류 해결 방법

크롤링을 하기위해서 beautifulsoup를 설치하게 됩니다.

파이참 툴을 사용중이라면 미설치된 라이브러리에 빨간줄이 생깁니다. 마우스 커서를 올리면 install package BeautifulSoup 처럼 파란색 글씨가 나타납니다.

클릭하여 설치할 수 도 있고, 단축키인 Alt+Shift+Enter 를 눌러서 설치할 수 도 있습니다.

설치할 때 다음과 같은 오류가 발생할 수 있어요.


Collecting BeautifulSoup Downloading BeautifulSoup-3.2.2.tar.gz (32 kB) 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 https://github.com/pypa/pip/issues/8333.

참고사항으로 파이썬3에서는 BeautifulSoup-3.2.2.버전을 사용할 수 없습니다.

BeautifulSoup 4를 사용해야합니다.

설치방법은 터미널창을 열거나 명령프롬프트(cmd)를 열고 pip install beautifulsoup4 명령어를 실행합니다.

또 다른 설치 방법은 os모듈을 import 후 os.system()함수를 사용하여 명령어를 실행할 수 있습니다.

>>> import os
>>>
>>> os.system("pip install beautifulsoup4")
Requirement already satisfied: beautifulsoup4 in c:\users\ilike\appdata\local\programs\python\python39\lib\site-packages (4.9.3)
Requirement already satisfied: soupsieve>1.2 in c:\users\ilike\appdata\local\programs\python\python39\lib\site-packages (from beautifulsoup4) (2.0.1)
>>>
>>>

마지막으로 import 해야하는 모듈을 변경해야 합니다.

AS-IS

import requests, BeautifulSoup

TO-BE

from bs4 import BeautifulSoup
