每当我使用vagrant在虚拟机上运行Flask应用程序时，都会显示错误“ OSError：[Errno 8] Exec format error”

Question

我是不熟悉烧瓶的人，正在尝试使用虚拟机在流浪汉中运行我的基本烧瓶代码。以下是我的代码：

from flask import Flask

app = Flask(__name__)


@app.route('/')
@app.route('/hello')
def HelloWorld():
    return "Hello World"


if __name__ == '__main__':
    app.debug = True
    app.run(host='0.0.0.0', port=5000)

每当我尝试在终端中以python file-name.py 的身份运行代码时，都会收到以下错误消息：

 * Serving Flask app "project" (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

我有一台Windows计算机，并在无业游民的VM上运行以下代码。

有人可以帮助我吗？非常感谢您的帮助。

这是针对流浪者上的VM的。我试图更改端口和主机地址，我同时在python解释器（2.7和3.6）上运行，但最终都没有解析。 它在主机（在我的情况下是Windows）中可以正常运行，但在无业游民中则无法使用。
