当我忘记更新我的 requirements.txt 文件以使用 Django>=3.1.0,<3.2.0，而不是姜戈 3.0.8。我还必须在更新后 运行 docker-compose 构建。
我在尝试 运行 我的服务器上的应用程序时遇到了同样的问题。
在本地 (ubuntu-20.04) 它适用于
- Python==3.6.7
- Django==3.1.3
但是在我的服务器 (debian-stretch) 上使用相同版本的 django 和 python，我遇到了同样的问题！
我试过 django==3.0，问题依然存在
Nov 05...gunicorn[19911]: created_group = models.JSONField(default=default_created_group)
Nov 05...gunicorn[19911]: AttributeError: module 'django.db.models' has no attribute 'JSONField'
应用新 models JSONField recommendation 的唯一方法是使用 Django 3.1
我看到这个错误是因为我在我的项目中使用 pipenv 并且在 运行 应用程序之前忘记了 运行 pipenv shell 命令。
实际上我们的 wwwroot 文件夹包含错误的文件和文件夹，这些文件和文件夹可以追溯到以前的 git 推送从未清理过，其中一个旧安装的 Django v3.0.5 没有被删除。
使用 FTP ftps://...ftp.azurewebsites.windows.net/site/wwwroot 访问 wwwroot 并清除其所有内容解决了这个问题。

当我忘记更新我的 requirements.txt 文件以使用 Django>=3.1.0,<3.2.0，而不是姜戈 3.0.8。我还必须在更新后 运行 docker-compose 构建。
我在尝试 运行 我的服务器上的应用程序时遇到了同样的问题。 在本地 (ubuntu-20.04) 它适用于
- Python==3.6.7
- Django==3.1.3
但是在我的服务器 (debian-stretch) 上使用相同版本的 django 和 python，我遇到了同样的问题！ 我试过 django==3.0，问题依然存在
Nov 05...gunicorn[19911]: created_group = models.JSONField(default=default_created_group)
Nov 05...gunicorn[19911]: AttributeError: module 'django.db.models' has no attribute 'JSONField'
应用新 models JSONField recommendation 的唯一方法是使用 Django 3.1
我看到这个错误是因为我在我的项目中使用 pipenv 并且在 运行 应用程序之前忘记了 运行 pipenv shell 命令。
实际上我们的 wwwroot 文件夹包含错误的文件和文件夹，这些文件和文件夹可以追溯到以前的 git 推送从未清理过，其中一个旧安装的 Django v3.0.5 没有被删除。
使用 FTP ftps://...ftp.azurewebsites.windows.net/site/wwwroot 访问 wwwroot 并清除其所有内容解决了这个问题。
