pycharm flask项目未创建sqlite文件

如何解决pycharm flask项目未创建sqlite文件

我正在使用pycharm创建一个flask项目。

问题是，如果我使用python app.py之类的命令来运行它应该执行的代码，并且我从flask中获得了以下输出：

 * Serving Flask app "app" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Restarting with stat
database C:\Users\jalco\PycharmProjects\pypi_new\db\pypi.sqlite
 * Debugger is active!
 * Debugger PIN: 192-734-348
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

但是在PyCharm中运行它却可以python.exe -m flask run 我得到以下输出：

FLASK_APP = app.py
FLASK_ENV = development
FLASK_DEBUG = 1
In folder C:/Users/jalco/PycharmProjects/pypi_new
C:\Users\jalco\PycharmProjects\pypi_new\venv\Scripts\python.exe -m flask run
 * Serving Flask app "app.py" (lazy loading)
 * Environment: development
 * Debug mode: on
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 185-154-487
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

PyCharm似乎正在跳过完全创建数据库的功能，并且仅运行任何与flask相关的功能，PyCharm中是否有我未设置的设置，或者其他人遇到过此问题吗？

初始化sqlite数据库的代码：

import sqlalchemy as sa
import sqlalchemy.orm as orm

from data.modelbase import SqlAlchemyBase

factory = None


def global_init(db_file: str):
    global factory

    if factory:
        return

    if not db_file or not db_file.strip():
        raise Exception("You must specify a db file")

    conn_str = 'sqlite:///' + db_file.strip()

    engine = sa.create_engine(conn_str,echo=False)
    factory = orm.sessionmaker(bind=engine)

    # noinspection PyUnresolvedReferences
    from data.package import Package
    SqlAlchemyBase.metadata.create_all(engine)

app.py的代码

import os
import sys
import flask
import data.db_session as db_session

folder = os.path.abspath(os.path.join(os.path.dirname(__file__),'..'))
sys.path.insert(0,folder)

app = flask.Flask(__name__)


def main():
    register_blueprints()
    db_file = setup_db()
    app.run(debug=True)


def setup_db():
    db_file = os.path.join(
        os.path.dirname(__file__),'db','pypi.sqlite')

    db_session.global_init(db_file)

    return db_file


    if __name__ == '__main__':
        main()
