Google app engine dev_appserver.py问题

Question

我只是从google app engine开始，我遵循了googleappengine上的基本hello world示例。

https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld

在helloworld文件夹中创建了两个文件。

我不想使用GUI，我更喜欢使用mac终端来处理这个应用程序。我想通过终端在本地主机local host:80上启动这个应用程序。

在本地运行我的基本helloworld应用程序

$dev_appserver.py地狱世界。但我知道这个错误。

    with open(configuration_path) as f:
IOError: [Errno 2] No such file or directory: 'helloworld'

我在helloworld目录中有两个文件。 应用程序yaml

application: your-app-id
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: helloworld.application

还有地狱世界

import webapp2

class MainPage(webapp2.RequestHandler):

    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Hello, World!')


application = webapp2.WSGIApplication([
    ('/', MainPage),
], debug=True)

我也有同样的问题。经过一番努力，在google_appengine目录中而不是在helloword目录中对我有效的命令是：

python dev_appserver.py helloworld/

也许这会有帮助。

1. 当您第一次启动Google App Engine时，会出现一个提示，询问您是否要创建“Command Symlinks”--确保单击OK，然后输入管理员密码。这使您能够使用/usr/local/bin文件夹中的符号链接来执行命令dev_appserver.py。

2. 在终端中输入以下内容（命令行）

   $: /usr/local/bin/dev_appserver.py helloworld
   

这是我的浏览器、终端和查找窗口的外观。

作为参考，here是在mac上安装/运行google app engine的O'Reilly指南。

1. 要关闭web服务器，请确保终端窗口处于活动状态，然后按Control-C

Answer 3

在安装了google cloud sdk之后，您是否运行了

gcloud components install app-engine-go

从组织的角度来说，文件有点荒谬。我刚开始的时候完全错过了
