我在安装我的Django Web应用程序的pythonanywhere中反复得到[NameError：名称'_mysql'未在其中定义”？

编程问答 2022-08-12

问题描述

我已经安装了requirements.txt [MysqL，django等]。创建了数据库。在pythonanywhere外壳程序上迁移并查看了MysqL（具有与设置中相同的凭据）。一切都很好。所有的表都存在，但我找不到错误的地方。请帮助解决此错误。这些是相关文件：-

（django 3.1.1 python3 3.8.0 适用于Linux（x86_64）（使用EditLine包装器）的MysqL Ver 14.14 distrib 5.7.27）

自动生成的wsgi.py 

import os
import sys

# # assuming your django settings file is at '/home/proj/mysite/mysite/settings.py'
# # and your manage.py is is at '/home/proj/mysite/manage.py'
path = '/home/proj/proj'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'project3.settings'
# # then:
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

数据库设置。py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.MysqL','NAME': 'proj$proj','USER': 'proj','PASSWORD': '*****','HOST': 'proj.MysqL.pythonanywhere-services.com',}
}
