pyinstaller によるexe化のエラーメッセージと対処方法

Posted at

はじめに:PyInstallerによるexe化

  • python 3.7で作成したモジュールをpythonと導入していない他の端末で使用するために、exe化をしたかった
  • 端末状況:
    • OS: Windows 7
    • python: 3.7
    • PyInstaller: 3.4

exe化のための実行コマンド

  • コマンドプロンプトで実行
    • 1回目:python3 -m PyInstaller ***.py --onefile --clean
    • 2回目(エラー1対応後):python3 -m PyInstaller ***.spec --onefile --clean
    • 変更点:***.py ⇒ ***.spec

エラー1:RecursionError: maximum recursion depth exceeded while calling a Python object

import sys
sys.setrecursionlimit(5000)

エラー2:WARNING: Cannot read QLibraryInfo output: raised Expecting value: line 1 column 1 (char 0) when decoding:
