我是django的初学者。我正在做基于它的项目。项目有两个阶段。我完成了第一阶段并将代码上传到amazon ec2实例。完成第二阶段后，我添加了一些包，如python-social-auth，django-cors-headers，django-easy-maps，crispyforms。但现在它显示了corsheaders的导入错误和这个追溯我检查了虚拟环境和corsheaders包是否

请提出任何建议

Answer 1

使用pip：

pip install django-cors-headers

使用pipenv：

pipenv install django-cors-headers

Answer 2

您不需要安装任何东西，只需使用runserver：

python manage.py runserver

Answer 3

通过pip安装后我遇到了同样的问题。然后我下载了源代码并在问题消失后手动安装了django-cors-headers。

希望有所帮助。

Answer 4

您的设置可能有误。

INSTALLED_APPS = [
    "corsheaders"
    
]

Answer 5

从您的回溯中，您似乎没有在虚拟环境中运行Django应用程序。你可以做两件事：

在系统范围内安装django-corsheaders，以便您的应用可以使用或不使用虚拟环境
或者您激活虚拟环境并运行django应用程序（因为您已经确认在虚拟环境中安装了django-corsheaders。）

导入错误django corsheaders
