我的Pyramid应用程序在粘贴httpserver中运行时工作正常，但在Google应用引擎中引发异常。
/ hello / {name} url在粘贴服务器和app引擎
中都能正常工作/ test url在粘贴服务器中工作正常，但在app引擎中我得到了Traceback。
有什么想法吗？
from pyramid.config import Configurator
from pyramid.response import Response
def hello_world(request):
return Response('Hello %(name)s!' % request.matchdict)
def test(request):
return dict()
settings = {'mako.directories':'mako_templates'}
config = Configurator(settings=settings)
config.add_route('hello', '/hello/{name}')
config.add_route('test', '/test', view=test, renderer='test.mako')
config.add_view(hello_world, route_name='hello')
wsgi_app = config.make_wsgi_app()
来自谷歌应用引擎的回溯：

我对这些东西的背景很浅，所以这可能是错误的。
这是我的看法：要在金字塔中使用mako，您需要为Configurator提供一个设置字典，其中包含一个名为“mako.directories”的键，该键指向您的mako模板目录。该键可以是相对路径或绝对路径。
pyramid / mako_templating.py文件将相对路径转换为此行中的绝对路径：
directories = [ abspath_from_asset_spec(d) for d in directories ]
此转换在gae中无效（请参阅堆栈跟踪）。为了解决这个问题，我使用了Pyramid AssetResolver，如下所示：
from pyramid.path import AssetResolver
r = AssetResolver('appname')
full_mako_path = r.resolve('http/mako_templates').abspath()
然后，当您创建Pyramid Configurator时，您可以：
settings = {'mako.directories':full_mako_path}
config = Configurator(settings=settings)
在这种情况下，我的目录结构是：
/serve.py (contains wsgi app)
/app.yaml
/appname
/appname/http/mako_templates
...

试试这个：
将 Pyramid 和 Mako 文件夹放在app目录中名为framework的目录中。然后将这些代码行添加到导入下的主.py文件中：
import sys, os
framework_dir = "framework"
framework_dir_path = os.path.join(os.path.dirname(__file__), framework_dir)
sys.path.insert(0, framework_dir_path)
