Django python manage.py runserver 给出异常数据文件未找到，数据文件生成失败
Django python manage.py runserver giving exception Datafile not found, datafile generation failed
升级我的一个包（django-registration）后，我在尝试 运行 python manage.py runserver
时收到此错误
输出如下所示。
我以为
python3.5/site-packages/confusable_homoglyphs/categories.py
可能丢失了，我重新安装了软件包 confusable_homoglyphs，但没有用。它抛出了同样的错误
还有之后，
在我的项目文件夹中创建了一个文件名 =3.0.0.txt，它写在下面
Requirement already satisfied: confusable_homoglyphs in ./myvenv/lib/python3.5/site-packages
我试图删除该包并添加该包（即使在我的虚拟环境之外的 n 内）。但它抛出了与下面相同的错误。

您正试图在 Django 中访问 categories.json 此文件您无法直接访问该文件。由于发生异常。
使用以下解决方案访问 categories.json
from project_name.settings import BASE_DIR
import os
file_path = os.path.join(BASE_DIR, 'categories.json')
categories_data = load(file_path)
BASE_DIR 给你你的项目目录路径，然后你想使用 os.path.join()
加入你的文件路径
希望对您有所帮助
此问题已在
之前提出
https://github.com/vhf/confusable_homoglyphs/issues/7
我现在可以通过 manage.py 运行 我的服务器了，似乎包有问题
confusable_homoglyphs
它会在加载时下载文件。当依赖项经常被下载时，它会产生问题，这会导致
ConnectionResetError: [Errno 104] Connection reset by peer
感谢评论中提供的link，补丁已经应用并且可以很好地与confusable_homoglyphs>=3.0.0.
一起使用
运行 带有选项 --no-site-packages 的 virtualenv 将不包括全局安装的包。它可能有助于保持包列表干净，以防以后需要访问它
为了保持环境一致，我“冻结”了环境包的当前状态
