Django 警告和错误

Question

我正在做一个小宠物项目。在我将所有工作提交到 git 存储库并将其克隆到新位置之前，一切似乎都很好。

我已经用我正在使用的所有模块设置了一个新的虚拟环境，但令我惊讶的是：我无法运行任何东西。例如，当我尝试运行测试用例时，我收到了弃用警告和错误（请参阅下面的输出）。

有人有想法吗？

Answer 1

根据 Django 的版本，如果是 1.7 或更低版本，我建议执行同步数据库和假迁移。

python manage.py syncdb --all
python manage.py migrate --fake

如果它大于 1.7，请确保在添加或更改模型时创建迁移，然后应用它。

python manage.py makemigrations app_name
python manage.py migrate app_name

更多信息请参考https://docs.djangoproject.com/en/1.8/topics/migrations/

另一种选择是，您在第一个 virtualenv 上使用的某些软件包与第二个不同。如果你还有原来的工作版本，我建议你做一个 pip freeze，然后在新的 virtualenv 上安装要求。

正在运行 virtualenv（确保您在项目目录中）

pip freeze > requirements.txt

在新的 virtualenv 上

pip install -r requirements.txt

希望对您有所帮助！
