(Error) OSError: (WinError 6) 句柄无效，当运行 python manage.py shell 时，我不明白发生了什么？

Question

models.py 文件

# Create your models here.
class Flight(models.Model):
    origin = models.CharField(max_length=64)
    destination = models.CharField(max_length=64)
    duration = models.IntegerField(null=False)

然后我在终端中运行 python manage.py shell

python manage.py shell

发生上述错误，我该如何解决这个问题，请帮忙。

Answer 1

错误的原因是 Django 5.0 与 Python 3.8 不兼容，要消除此错误只需升级到该语言的兼容版本，Django 5.0 支持 Python 3.10、3.11 和 3.12

此外，Django 4.2。 x系列是最后支持Python 3.8和3.9的，如果你确实需要在Python 3.8或3上开发你的项目。
