我正在尝试在我的 windows 10 64 位 pc 上设置一个新项目

这样做时，python manage.py makemigrations我不断收到ModuleNotFoundError: No module named 'qrcode.settings'

我已经成功安装了所有依赖项，在 venv 中运行了 cmd。

我寻找这个特定的问题，但找不到解决方案。我正在使用 Python 3.9。

依赖项是（点冻结）

请注意，我已经完成了

pip install qrcode

pip install qrcode[pil]

pip install PyQRCode

来自 qr app 的 models.py 代码如下

 from django.db import models
from django import forms
from user.models import User
import datetime

# Class name starts with capital letter
class QR(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    description = models.CharField(max_length=255, blank=True)
    qr_identifier = models.CharField(max_length=255, blank=True)
    size = models.FloatField(default=0.0, blank=True)
    active = models.BooleanField(default=True, help_text='Active / Inacitve.')
    # TODO: Remove the default=1 parameter
    created_by_user = models.ForeignKey(User, on_delete=models.CASCADE, default=1)
    created_at = models.DateTimeField(editable=False, auto_now_add=True)
    

class QRFile(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    location = models.FileField(upload_to='documents/')
    size = models.CharField(max_length=200, null=True, blank=True)
    media_type = models.CharField(max_length=200, null=True, blank=True)
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)

class QRURL(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    URL = models.CharField(max_length=200, null=True, blank=True, default="Product Link")
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)
    
class QRScan(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)
    scanned_at = models.DateTimeField(editable=False, default=datetime.datetime.now)
    comment = models.CharField(max_length=255, null=True, blank=True)

您的项目被调用qrcode，因为 Django 的设置模块的默认路径是

<project name>.settings

在你的情况下转化为

qrcode.settings

Django 正在从qrcode库中导入设置。要解决此问题，请将您的项目重命名为与库名称不冲突的名称。

manage.py手动重命名项目后，您必须对wsgi.py文件进行适当的更改。
