Jinja2的问题：TemplateNotFound：index.html [英] Problems with Jinja2: TemplateNotFound: index.html
问题描述
我试图用jinja2构建我的第一个GAE应用程序。在克服了十几个小错误后，现在我坚持了这一点：
I'm trying to build my first GAE app with jinja2. After overcoming a dozen small errors, now I'm stuck with this:
Traceback (most recent call last):

TemplateNotFound: index.html
这里是我的yaml文件：
Here my yaml file:
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"
这里是我的代码：
Here my code:
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)
这里是我的.html模板：
Here my .html template:
<!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>
尽管有错误信息，但我有一个名为templates的文件夹，并在其中创建索引.html文件：
Despite the error message, I have a folder called "templates" and, within it, created the index.html file:
我也安装了jinja2。
I also have installed jinja2.
现在有谁知道这个错误的原因吗？
Does anyone have any idea of the cause of this error now?
推荐答案
好吧，我的错误简单而愚蠢。
我以错误的方式创建了文件index.html（这里是正确的方式）。所以，我的index.html文件确实是一个.text文件（因为我只是将它重命名为index.html而不是另存为index.html）。
感谢您的帮助，各位！
Well, my error was simple and silly. I have create the file "index.html" the wrong way (here the right way). So, my "index.html" file was indeed a ".text" file (because I just rename it to "index.html" instead of "save as" index.html"). Thanks for the help, guys!
