我一定是做了什么傻事。我正在Google App Engine上运行以下代码:
class MainHandler(webapp.RequestHandler):
def render(self, template_name, template_data):
path = os.path.join(os.path.dirname(__file__), 'static/templates/%s.html' % template_name)
self.response.out.write(template.render(path, template_data)) # error here
def get(self):
self.response.out.write("hi")
def main():
application = webapp.WSGIApplication([('/', MainHandler)],
debug=True)
util.run_wsgi_app(application)
if __name__ == '__main__':
main()
这会产生错误:
Traceback (most recent call last):
File "C:\Program Files\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3192, in _HandleRequest

我做错了什么?
