谷歌应用引擎dev_appserver.py问题

Question

我刚开始使用谷歌应用引擎,我在谷歌应用引擎上关注了基本的hello world示例.

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

在helloworld文件夹中创建了这两个文件.

我不想使用GUI,我更喜欢使用mac终端来使用这个应用程序.我想在我的本地主机localhost:80上通过终端启动此应用程序.

我在本地运行我的基本helloworld应用程序

$ dev_appserver.py helloworld.但是我得到了这个错误.

Traceback (most recent call last):

    _run_file(__file__, globals())
  File "/usr/local/bin/dev_appserver.py", line 180, in _run_file

    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.的app.yaml

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

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

和helloworld.py

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)

Answer 1

安装google cloud sdk后，你运行了吗

gcloud components install app-engine-go

该文档在组织方面有点荒谬。我刚开始的时候完全错过了这个

Answer 2

我有同样的问题。经过一番努力，对我有用的命令（在google_appengine目录中而不是在helloword目录中）是：

python dev_appserver.py helloworld/

也许这有帮助。
