坏文件描述符 - Heroku Foreman

Question

我正在尝试从这个Python Heroku教程中运行hello.py.运行此命令后我的问题开始了:.即使我安装了Heroku Toolbelt,我也收到以下错误:foreman start

工头不被视为内部或外部命令,可操作程序或批处理文件

所以我将foreman文件(版本0.63.0)的位置添加到我的路径:

C:\ Program Files(x86)\ Heroku\ruby​​-1.9.2\bin

并重新启动命令提示符并重新启动foreman start.现在,我收到了这个错误:

hello.py

import os
from flask import Flask

app = Flask(__name__)

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

Procfile

web: gunicorn hello:app

看完这个答案后,我做了以下几点:

gem uninstall foreman   
gem install foreman -v 0.61.0

但是,当我重申foreman start我现在收到这个错误

(venv) C:\Users\me\Desktop\Code\heroku_python_app>foreman start
14:13:20 web.1  | started with pid 252
14:13:20 web.1  | exited with code 1

pts\gunicorn-script.py", line 9, in <module>

(venv) C:\Users\me\Desktop\Code\heroku_python_app>

任何帮助将非常感谢.提前致谢.
