Question

我成功安装了django-multiselectfield，但是它不起作用。这些是我运行lib的步骤：

pip3安装django-multiselectfield
INSTALLED_APPS = [
＃...，
'multiselectfield'
] 另外，我确实创建了requirements.txt文件，但错误没有消失，如何成功安装此lib

models.py

from multiselectfield import MultiSelectField
class PlayerName(models.Model):
    match = models.ForeignKey(Match, on_delete=models.CASCADE, related_name='player_name')
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name


PLAYERS = PlayerName.objects.values_list('name', 'name')


class PlayerBox(models.Model):
    player_name = models.ForeignKey(PlayerName, on_delete=models.CASCADE, related_name='player_box')
    name = MultiSelectField(choices=PLAYERS)

ModuleNotFoundError: No module named 'multiselectfield'

如何解决该问题：没有名为“ multiselectfield”的模块？
