NotImplementedError:无法针对未注册的加载器类型执行此操作 [英] NotImplementedError: Can't perform this operation for unregistered loader type

问题描述

我正在制作一个小的脚本来生成HTML文件.为此，我正在使用jinja2.

I'm making a small script to generate an HTML file. For this purpose, I'm using jinja2.

这是我的脚本(在jinja2文档中找到):

This is my script (found in the jinja2 documentation):

# -*- coding: utf-8 -*-

from jinja2 import Environment, PackageLoader

env = Environment(loader = PackageLoader('monapplication', 'templates'))
template = env.get_template('index.html')
print(template.render(message = "Bienvenue sur mon site !"))

"monapplication"软件包包含index.html文件所在的文件夹"templates".

The package "monapplication" contains the folder "templates" where my index.html file is located.

但是当我运行脚本时，出现此错误:

But when I run the script, I get this error:

"NotImplementedError；无法对未注册的用户执行此操作 加载程序类型."

"NotImplementedError; Can't perform this operation for unregistered loader type."

我做了一些研究，但没有找到解决我问题的方法.

I did some research, but I didn't find any solution for my problem.

我的操作系统是Windows 10.

推荐答案

我遇到了同样的问题.问题在于"monaaplication"被称为目录，而不是python软件包.

I had the same issue. The problem was that 'monaaplication' was known as a directory and not a python package.

尝试将 __ init __.py 文件添加到目录"monaaplication". (这就是告诉Python将这个目录视为一个包的原因.)

Try to add an __init__.py file to the directory 'monaaplication'. (This is what tells Python to treat this directory as a package.)
