python:: pyinstaller로 exe변환시 오류, "NoneType"

 

 

Local 실행할 때는 문제없던 앱이 pyinstaller로 변환하고 나면 에러가 발생한다.

Failed to convert files: Error converting test.docx: docx2pdf Conversion failed: 'NoneType' object has no attribute 'write'

 

 

** Pyinstaller로 Non-windowd 옵션으로 변환하면 porcess를 보여주는 라이브러리의 결과 생성을 뿌려줄 곳이 없어지면서 발생하는 오류임

import os
import docx2pdf
 
# 1. 출력 폴더가 존재하는지 확인하고 없으면 생성
output_folder = "_convert"
if not os.path.exists(output_folder):
    os.makedirs(output_folder)
 
try:
    # 2. 명시적인 경로 사용 (상대 경로 대신 절대 경로)
    input_path = os.path.abspath("test.docx")
    output_path = os.path.abspath(os.path.join(output_folder, "test.pdf"))
    
    # 3. 디버깅 정보 출력
    print(f"입력 파일: {input_path}")
    print(f"출력 파일: {output_path}")
    
    # 4. 변환 시도
    docx2pdf.convert(input_path, output_path)
    
except Exception as e:
    print(f"변환 오류 발생: {e}")
    # 오류 상세 정보 출력
    import traceback
    traceback.print_exc()

PyInstaller 관련 추가 해결책

1. --hidden-import 옵션 사용:

pyinstaller --hidden-import=win32com.client --hidden-import=docx2pdf your_script.py

2. spec 파일에 Word COM 객체 관련 설정 추가:

a = Analysis(
    ['your_script.py'],
    pathex=[...],
    binaries=[...],
    datas=[...],
    hiddenimports=['win32com.client', 'win32com', 'docx2pdf'],
    ...
)
