我刚刚开始使用谷歌应用引擎,并且我在谷歌应用引擎上遵循了基本的Hello World例子。谷歌应用引擎dev_appserver.py问题
https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld
中的HelloWorld文件夹中创建两个文件。
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localhost:80上启动这个应用程序。
运行我的基本的HelloWorld应用程序在本地所有我要说的是
$ dev_appserver.py的HelloWorld。但我得到这个错误。

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)
错误说没有文件或目录。 helloworld目录是否存在于您运行该命令的目录中,并且是否有app.yaml? –
事实上,我更新了我的文章,其中包含两个文件。在运行dev_appserver.py之前,我确保cd进入目录,但仍然不行。 – muhammed
如果你进入'helloworld'目录,那么这个命令应该是'dev_appserver.py .'这个参数是一个包含app.yaml的目录的路径。如果你在那个目录下,那么路径就是当前目录或'.'的完整路径 –
