Google app engine 每次修改源后都会发生错误

我正在尝试在谷歌应用程序引擎中使用i18n和jinja2

我在这里找到了一个教程

除了一件事，一切都很好

每次修改导入webapp2_extras.i18n的.py文件后，我都会遇到一个错误

这是错误消息

这是“app.yaml”

application: simpletest
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: simpletest.app

libraries:
- name: jinja2
  version: latest

在我的应用程序目录中有babel和pytz库目录

第一次启动dev服务器后，一切正常。我能很好地看到我的网页

但是，如果我只是在simpletest.py中添加了额外的[enter]，则会出现错误。

这不是一个真正的答案，只是另一个解决方法。。尝试禁用：

C:\\Program Files\\Python27\\lib\\site-packages\\setuptools-0.6c11-py2.7.egg

将其重命名为：

setuptools-0.6c11-py2.7.egg_DISABLED

---

您需要重新启用它以安装本地Python软件包，但是，如果我是对的，它将解决您的问题。

谢谢！你的答案有效。我还从我不知道为什么会出现问题的地方找到了另一个解决方案。

setuptools-0.6c11-py2.7.egg_DISABLED
