我在Linux机器（AWS中）的Django项目中使用：
- Python 3.5.1
- Django 1.11.7
我为我的项目创建了虚拟环境，并且所有依赖项都已经完美地安装在那里。关于数据库，我使用sqlite3。版本详情如下。
>>>import sqlite3
>>>sqlite3.version
'2.6.0'
>>>sqlite3.sqlite_version_info
(3, 7, 17)
在 settings.py 文件中，DATABASES 部分如下：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
当我运行runserver时，出现了一个异常，sqlite3.NotSupportedError: URIs not supported ，这导致了一个错误django.db.utils.NotSupportedError: URIs not supported，我无法修复它。
我已经阅读了像djangoproject.com和google.forum这样的文章，但仍然无法理解此错误的原因。 我还尝试执行python manage.py makemigrations，但同样的错误也出现了。
注意：在Windows机器上，我的项目可以正常运行。
请参见下面的跟踪：
# python manage.py runserver

The above exception was the direct cause of the following exception:

请帮助理解并修复此错误。在堆栈中没有与此问题相关的帖子，也没有在谷歌上找到任何相关信息。
django.db.backends.sqlite3.base大约在第 194 行设置了uri为True。如果我将其注释掉，它就可以工作了。 - leech
