Я пытаюсь поместить простой сервер flask в исполняемый файл с помощью pyinstaller -F server.py command

При запуске exe-файла я получаю следующую ошибку:

 Traceback (most recent call last):

код server.py

 from flask import Flask, request, jsonify

from transform import transform_text

server = Flask(__name__);

@server.route('/send', methods=['POST'])
def send():
    print("POST /send request")

    # obtaining passed args
    fname = request.json['fname']
    text = request.json['text']

    # updating the text
    text = f"{transform_text(text, 'Masc', fname)}"

    # sending back updated text
    return jsonify({'text': text})

if __name__ == '__main__':
    server.run(host='0.0.0.0', port='8080', debug=True)
 

tranform_text() функция использует pymorphy для изменения предложений с формы от 1-го лица («Я играю») на форму от 3-го лица («Он / она играет»)

Итак, есть ли какой-нибудь способ заставить исполняемый файл работать?

Это проблема пакета;pymorphy2_dicts_ru;. Файлы из каталога данных не копируются в пакет.

Чтобы решить проблему, вам необходимо выполнить два шага:

1. Добавьте каталог данных в файл спецификации pyinstaller:

    ...
   # pymorph data
   import pymorphy2_dicts_ru
   pymorph_data = pymorphy2_dicts_ru.get_path()
   
   a = Analysis(['main.py'],
            pathex=['.'],
            binaries=[],
            datas=[(pymorph_data, 'pymorphy2_dicts_ru/data')],
            hiddenimports=[],
            hookspath=[],
   ...
    

2. Задайте путь к каталогу данных в коде перед импортом модуля pymorphy2 (в main.py например):

    ... 
   if getattr(sys, 'frozen', False) and hasattr(sys, '_MEIPASS'):
       os.environ["PYMORPHY2_DICT_PATH"] = str(pathlib.Path(sys._MEIPASS).joinpath('pymorphy2_dicts_ru/data'))
   ...
