【中文标题】在 Visual Studio 中为其他版本的 Django 创建生成的新项目【英文标题】：Creating New Project Generated for other version of Django in Visual Studio 【发布时间】：2018-08-26 02:19:08 【问题描述】：

为什么每次我在 Visual Studio 中创建一个新项目时，它都使用 1.9.1 版本的 Django 而不是 2.0.3 版本？我必须创建项目，然后将 Django 的版本升级到 2.0.3，因为它会导致我在使用其他版本的 Django 时遇到 MIDDLEWARE 问题。

在我的 settings.py 中：

"""
Django settings for pruebadelaprueba project.

Generated by 'django-admin startproject' using Django 1.9.1.

STATIC_URL = '/static/'

STATIC_ROOT = posixpath.join(*(BASE_DIR.split(os.path.sep) + ['static']))

然后我去安装 Python 包

然后用箭头将 Django 升级到 2.0.3。但文件 settings.py 保持不变。

我的问题是为什么每次创建新项目时都必须这样做？如何使更改保持不变？

感谢您的帮助！

最简单的解决方案之一是，在具有所需 django 版本的虚拟环境中运行此命令。
