TemplateNotFound：将网站部署在Google App Engine上但在本地主机中运行时网站运行正常时，templates / HomePage.html错误

Question

I am trying to deploy my personal website but I am running into a big error when I run my website in local host everything runs fine.But I have deployed my website via Google App but it does not work. I keep getting this error below Here is a screenshot of the error I get

I don't know why it is doing this because that Homepage.html file is inside of the template folder. This a screenshot of my file path and the Python code I wrote . This the code I wrote

import jinja2
import os
import webapp2
import logging
from google.appengine.api import users
from google.appengine.ext import ndb
import datetime
import json
import unicodedata
from google.appengine.api import users

 # the two lines of code below makes the jinja work
jinja_environment = jinja2.Environment(loader=
    jinja2.FileSystemLoader(os.path.dirname(__file__)))

class HomePage(webapp2.RequestHandler):
    def get(self):
        template = 
jinja_environment.get_template('templates/HomePage.html')
        self.response.write(template.render())

class AboutMe(webapp2.RequestHandler):
    def get(self):
        template = jinja_environment.get_template('templates/Aboutme.html')
        self.response.write(template.render())

class Contact(webapp2.RequestHandler):
    def get(self):
        template = jinja_environment.get_template('templates/Contact.html')
        self.response.write(template.render())


class Projects(webapp2.RequestHandler):
    def get(self):
    template = 
jinja_environment.get_template('templates/Projects.html')
        self.response.write(template.render())

app = webapp2.WSGIApplication([
    ('/', HomePage), #HomePage
    ('/AboutMe.html',AboutMe),
    ('/Contact.html',Contact),
    ('/Projects.html',Projects)

], debug=True)
}

here is my app.yaml file

application: israel-ali
version: 1
runtime: python27
api_version: 1
threadsafe: yes
# order matters always have this order
handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: /resources
  static_dir: static_folder

- url: .*
  script: main.app

libraries:
- name: jinja2
  version: latest
- name: webapp2
  version: "2.5.2"

Answer 1

Filenames are case sensitive on GAE.

Your code seeks a template called HomePage.html and (what I suspect to be) the actual template is called Homepage.html . And you have a similar problem with Aboutme.html vs. AboutMe.html .

You just need to use the actual filename in .get_template() .

Answer 2

Is the operating system you're using locally one that doesn't treat case in filenames as significant? If so, those template_get lines need to specify filenames exactly as they are on the filesystem.
