[Python] PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH? 해결방법

Python에서 pdf2image 라이브러리를 활용하여 pdf를 이미지로 변경하려는 코드를 실행하려고하니

아래와 같은 오류가 발생하였습니다.

from pdf2image import convert_from_path
pages = convert_from_path("./source/" + file_list[0], 500)

이 글에서는 위의 오류를 해결할 방법을 적어보려합니다.

 

저는 MAC OS Big Sur 환경에서 진행하였습니다.

 

 

MAC OS X 일 경우

MAC OS 에서는 brew를 활용하여 해결할 수 있습니다.

brew 설치는 아래의 링크를 참고 바랍니다.

[Mac OSX] Brew 설치하기

 

brew를 설치하였다면 poppler를 brew를 활용하여 설치합니다.

 $ brew install poppler 

 

Ubuntu 일 경우

 $ sudo apt-get install poppler-utils 

 

위의 방법을 활용한 이후에 다시 실행해보면 오류 없이 제대로 실행이 되는 것을 확인할 수 있습니다.
