Answer 1

运行以下命令： （根据您的操作系统编写 python，以下命令适用于 windows）

1) python manage.py makemigrations

然后

2) python manage.py 迁移

大多数情况下，这将使您的命令 python manage.py runserver 工作！

Answer 2

**没有名为“crispy_forms”的模块

这就是问题

或 命令是python manage.py runserver，而不是manage.py runserver

Answer 3

从您收到的错误消息中检查有一行：

ModuleNotFoundError: No module named 'crispy_forms'

这意味着在您的 settings.py 文件中，您在已安装的应用程序中有“crispy_forms”，但这次它不包含在您的 python 环境中。要解决此问题，您必须使用

安装crispy_forms

pip install django-crispy-forms

有关 django-crispy-forms 的更多信息，请参阅文档https://django-crispy-forms.readthedocs.io/en/latest/install.html

Answer 4

在我的例子中，我在主项目的 settings.py 文件中创建该应用程序之前添加了我的应用程序的名称。创建应用程序后，请在 settings.py 文件中添加应用程序的名称。这就是你无法运行服务器的原因

Answer 5

如果您遇到此问题，请转到settings.py 文件，检查是否有逗号，以及rest_framework 是否拼写正确。

Answer 6

确保处于您之前使用过的正确虚拟环境中，因为您之前安装的所有内容（如 rest_framework、django）都将存储在该环境中，然后尝试运行该命令。

python manage.py runserver
