尝试进行与缺少SQL包相关的迁移时出现多个错误

Question

我对Django和StackOverflow都是新手，所以我提前向你道歉。我不太确定如何格式化终端文本...

当我运行"python manage.py makemigrations myappname“时：

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb

我读了其他类似的问题，所以我尝试了"pip install MySQL-python“和许多其他版本，我得到了这个错误：

Command "python setup.py egg_info" failed with error code 1 in
/private/var/folders/vr/sgvcx9_n1hq4gtcknn7ln7d00000gn/T/pip-build-ON_V7M/mysql-python/

从那里，我尝试更新setuptools，并得到以下错误：

OSError: [Errno 13] Permission denied:
'/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib/__init__.py'

我被卡住了..。有什么想法？非常感谢！

最后一个错误意味着您没有足够的权限继续执行任务，您需要使用sudo运行该命令。

缺少的包是MySQL-python。您可以使用setuptools或pip安装它：

sudo easy_install MySQL-python sudo pip install MySQL-python

我建议您安装pip并使用它来管理项目的依赖项：sudo easy_install pip。安装pip后，您可以简单地sudo pip install packagename。
