Question

也许这是一个错误，但无论如何我都在这里发帖。

我在本地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

感谢您的帮助！

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。例如，如果你有这样的模板目录：

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

你的app.yaml文件是这样的：

- url: /templates
  static_dir: templates

如果您使用此名称，则无法使用jinja2呈现模板：

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

我认为那是因为static_dir选项以某种方式阻止了jinja2的这个目录，至少我是这么认为的，也许它可以帮助别人！

Answer 2

只需从您的网站包中删除文件setuptools-0.6c11-py2.7.egg。

查找您的网站套餐的位置

启动python CLI：

python

列出网站包：

>>> import site; site.getsitepackages()

Answer 3

我现在使用的是：

，而不是使用硬编码的路径变量来引用我的变量

PROJECT_DIR = os.path.dirname(__file__)

它正在发挥作用。如果问题回来，我会告诉你（我看到一些文章描述它是随机的）。

我还在http://code.google.com/p/googleappengine/issues/detail?id=4339

的评论29中应用了补丁

Answer 4

可能会迟到但也许可以帮助其他人所以，当你添加

 po [self.feed feedItems]
<FeedItem: 0x7fe95a484540> (entity: FeedItem; id: 0xd000000007f40002 <x-coredata://918D3499-5129-4D78-8F37-3D8D478FE482/FeedItem/p509> ; data: <fault>)

2016-07-10 14:17:33.176 RSFeedReader[98980:14910776] -[FeedItem allObjects]: unrecognized selector sent to instance 0x7fe95a484540

不要添加
jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__), 'templates'))
到 app.yaml 文件

Answer 5

我一直对类似问题感到困惑 - 从site-packages导入egg文件/包时出现IOError。我使用的是Ubuntu 13.10，GAE 1.8.8，virtualenv和python 2.7。

最后，我发现我无法使用easy_install导入我安装的任何东西（默认情况下将egg文件放入site_packages）。

一旦我卸下所有这些鸡蛋，并使用 pip install 命令重新安装，一切都开始正常工作。

希望这会节省一些时间，因为我永远不会浪费我的时间。

Answer 6

在某些情况下，当文件名与app.yaml中的skip_files模式匹配时，此错误是由dev_appserver.py导致打开调用失败引起的。即使在本地运行dev_appserver.py，也请检查app.yaml。
