当通过docker-compose运行时，Flask CLI抛出'OSError: [Errno 8] Exec format error'的错误。

我正在运行一个带有自定义脚本的Flask应用程序。无论如何，我正在尝试这样做。

我使用Windows 10，并且该应用程序应该在linux Docker容器中运行，命令如下：

docker-compose up api

Docker-compose的版本是1.23.2。在dockerfile中，api服务通过以下命令运行：

command: python manage.py run --host "0.0.0.0" --with-threads

在尝试启动时，我看到了以下异常：

OSError: [Errno 8] Exec format error: '/api/manage.py'

起初我认为这可能是可怕的Windows行尾符问题，但是在所有源文件上运行dos2unix并没有解决这个问题。

我该如何避免这个错误？

manage.py

    import click
    from flask.cli import FlaskGroup
    from my_app_api import create_app
    def create_my_app(info):
        return create_app()
    @click.group(cls=FlaskGroup, create_app=create_my_app)
    def cli():
        pass
    if __name__ == "__main__":
        cli()
