IOError:使用Google AppEngine 1.6.1无法访问[Errno 13]文件

Question

也许这是一个错误,但无论如何我都在这里发帖.

我在我的本地AppEngine测试服务器上遇到以下问题:

我可能错了,但似乎这是我以前没有遇到过的问题.自Google App Engine于2011年12月13日发布以来; 我想知道它是否可以来自这个版本.

我正在使用pythonbrew,virtualenv,Mac Os X 10.6.8

谢谢你的帮助!

Answer 1

我对他的问题有另一个答案,我自己也经历过这个问题.如果你有一个像这样的模板目录:

templates
|-- css
|-- img
|-- js
|-- html

你的app.yaml文件是这样的:

- url: /templates
  static_dir: templates

如果使用此名称,则无法使用jinja2呈现模板:

JINJA_ENVIRONMENT.get_template('html/index.html')

我认为这是因为static_dir选项以某种方式阻止了jinja2的这个目录,至少我是这么想的,也许它可以帮到某人!

Answer 2

只需setuptools-0.6c11-py2.7.egg从您的网站包中删除该文件即可.

找到您的网站包的位置

启动python CLI:

python

列出网站包:

>>> import site; site.getsitepackages()

Answer 3

我现在使用的不是使用硬编码路径变量引用我的变量：

PROJECT_DIR = os.path.dirname(__file__)

它正在发挥作用。如果问题再次出现，我会通知您（我看到一些文章将其描述为随机复发）。

我还在http://code.google.com/p/googleappengine/issues/detail?id=4339上的评论 29 中应用了补丁
