python - Google 应用引擎 dev_appserver.py 问题

Question

我刚开始使用 google app engine，我遵循了 google app engine 上的基本 hello world 示例。

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

在 helloworld 文件夹中创建了这两个文件。

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

要在本地运行我的基本 helloworld 应用程序，我所说的就是

$ dev_appserver.py helloworld .但我得到了这个错误。

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。应用.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)

安装google cloud sdk后，你运行了吗

gcloud components install app-engine-go

文档在组织方面有点荒谬。我刚开始的时候完全错过了这一点
