我正在使用 Ubuntu Server 13.10 和 Python 2.7。

我想要两个版本的 App Engine 应用程序：管理员版本和默认版本。我已经定义了这两个版本。目前，这是我的app.yaml文件：

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

handlers:
- url: /css
  static_dir: css
- url: /js
  static_dir: js
- url: /
  script: python.MainPage.application
- url: /test.*
  script: gaeunit.application

libraries:
- name: webapp2
  version: latest
- name: jinja2
  version: latest


version: admin
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /css
  static_dir: css
- url: /js
  static_dir: js
- url: /.*
  script: python.MainPage.application
  login: admin
  auth_fail_action: unauthorized
- url: /test.*
  script: python.MainPage.appication

libraries:
- name: webapp2
  version: latest
- name: jinja2
  version: latest

当我将此代码部署到 App Engine 时，它​​按预期工作。但是，如果我尝试使用dev_appserver.py在 Google Cloud SDK 中找到的运行它，它会因以下回溯而失败：

您可以在两个不同的端口上启动两个不同的开发应用程序服务器，只需使用--port=参数覆盖默认端口，但是您需要将两个app.yaml文件分开，而不是使用与您相同的文件。运行时dev_appserver.py，使用配置文件作为最终参数，而不是目录（默认为app.yaml）。

例如：

dev_appserver.py --port=8888 app_one.yaml
dev_appserver.py --port=9999 app_two.yaml

在测试之后和部署之前，请确保将最终文件保留为名称app.yaml；否则，您将无法完成该过程。
