pyinstaller に関するメモ

Last updated at Posted at 2021-06-02

#pyinstaller 起動オプション

pyinstaller xxxx.py --onedir --onefile --noconsole --clean
  • --onedir or -D
    出力を1ディレクトリにまとめる
  • --onefile or -F
    出力を1ファイルにまとめる
  • --noconsole or -w
    コンソールを表示しない
  • --clean
    ビルド前に前回のキャッシュと出力ディレクトリを削除

#pyinstallerで作ったモジュールでUnicodeEncodeErrorが出る対策
###標準出力の場合

import io, sys, logging
# 標準出力をUTF-8に設定
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')

###loggingの場合、ファイルハンドラに「encoding='utf-8'」を追加する。

# ファイル出力用ハンドラ
handler = FileHandler(filename=filename, encoding='utf-8')
handler.setLevel(_logging_level)
handler.setFormatter(Formatter(formatter))
logger.addHandler(handler)
