Question

我在Google Appengine中创建了一个新项目但是当我尝试通过localhost访问它时，我收到HTTP 500错误。我的浏览器说“localhost”目前无法处理此请求。＆＃39;以下是我的新项目代码：

的app.yaml：

application: hello-world
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.2"

main.py：

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello world!')

app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)

当我在命令行上运行以下命令时：

python "C:\Program Files (x86)\Google\google_appengine\dev_appserver.py" "C:\Users\Jason\Desktop\Hello World\hello-world"

我收到错误

  import webapp2

ImportError: No module named webapp2

INFO     2016-06-18 15:29:37,092 module.py:788] default: "GET / HTTP/1.1" 500 -

更新：此问题已在SDK版本1.9.40中修复。

a GAE issue导致SDK版本1.9.37中引入此行为，请参阅"ImportError: No module named webapp2" after Linux SDK upgrade (1.9.35 -> 1.9.38)。

如果您的SDK版本是1.9.37或1.9.38降级到1.9.36，您可以找到here。至少在解决方案发布之前。
