我正在尝试使用 jinja2 构建我的第一个 GAE 应用程序。在克服了十几个小错误之后,现在我陷入了困境:
回溯(最近一次通话最后):
File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1536, in __call__
rv = self.handle_exception(request, response, e)

File "C:\Program Files (x86)\Google\google_appengine\lib\jinja2\jinja2\loaders.py", line 180, in get_source
raise TemplateNotFound(template)
TemplateNotFound: index.html
这是我的yaml文件:
application: himother
version: 1
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
- url: .*
script: main.app
libraries:
- name: webapp2
version: "2.5.1"
- name: jinja2
version: "2.6"
这是我的代码:
import os
import webapp2
import jinja2
jinja_environment = jinja2.Environment(autoescape=True,
loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__), 'templates')))
class MainPage(webapp2.RequestHandler):
def get(self):
template_values = {
'name': 'Serendipo',
'verb': 'extremely happy'
}
template = jinja_environment.get_template('index.html')
self.response.out.write(template.render(template_values))
app = webapp2.WSGIApplication([('/', MainPage)],
debug=True)
这是我的 .html 模板:
<!DOCTYPE html>
<html>
<head>
<title>Look Ma, I'm using Jinja!</title>
</head>
<body>
Hi there - I'm {{ name }}, and I {{ verb }} programming!
</body>
</html>
尽管出现错误消息,但我有一个名为“templates”的文件夹,并在其中创建了 index.html 文件:
我也安装了jinja2。
现在有没有人知道这个错误的原因?
