错误111以下WERKZEUG教程“不久”后

我遵循WERKZEUG "Shortly" here 错误111以下WERKZEUG教程“不久”后

教程，我提交有效的URL后收到此错误信息。

Traceback (most recent call last)

    raise ConnectionError(self._error_message(e)) 

    ConnectionError: Error 111 connecting localhost:6379. Connection refused.

该错误消息表示，有一些错误的本地主机：6379 代码的相关部分是在这里：

def create_app(redis_host='localhost', redis_port=6379, with_static=True): 
    app = Shortly({ 
     'redis_host':  redis_host, 
     'redis_port':  redis_port 
    }) 
    if with_static: 
     app.wsgi_app = SharedDataMiddleware(app.wsgi_app, { 
      '/static': os.path.join(os.path.dirname(__file__), 'static') 
     }) 
    return app 

if __name__ == '__main__': 
    from werkzeug.serving import run_simple 
    app = create_app() 
    run_simple('127.0.0.1', 5000, app, use_debugger=True, use_reloader=True)

这意味着，在服务器上的本地主机上运行，当然：5000。那么为什么create_app函数中有另一个端口号？这使我困惑了一下。

什么是错误信息？你怎么知道它是关于端口6379？ – tayfun

@tayfun看看回溯的底部... – MattDMo

如果你用'6379'替换'5000'，反之亦然？ – MattDMo

我不太熟悉werkzeug，但它看起来像缺少redis服务器，请使用您喜欢的软件包管理器安装一个，然后重试。

谢谢。我通过pip安装了redis和jinja2，但出于某种原因，这还不够。 'sudo apt-get install redis-server python-jinja2'帮助了我。 – Sadik

不客气。是的，redis需要作为服务器程序安装，而不是作为库，因为它似乎已经有了python连接库。 – tayfun
