Question

Django配置MySQL数据库，报错TypeError: 'tuple' object is not callable

settings.py改动：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME':'django_try',
        'USER':'root',
        'PASSWORD':'MySQL110927'
    }
}

init.py改动：

import pymysql

pymysql.version_info(1,3,13,"final",0)
pymysql.install_as_MySQLdb()

报错：

本答案参考通义千问

这个错误是因为在尝试调用 pymysql.version_info 时，将其作为函数调用，但实际上是作为一个元组来获取版本信息。解决这个问题，你需要将 pymysql.version_info 从括号中移除，直接使用它作为变量：

settings.py 的改动：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'django_try',
        'USER': 'root',
        'PASSWORD': 'MySQL110927'
    }
}

init.py 的改动：

import pymysql

# 不需要调用 version_info 了，因为这只是一个元组，不是函数
# pymysql.version_info(1,3,13,"final",0)

# 如果你想检查版本，你可以这样：
version_tuple = pymysql.version_info
print("MySQLdb version:", version_tuple)
pymysql.install_as_MySQLdb()

这样，你就不需要调用 version_info 作为函数，而是直接使用它作为变量。然后继续配置你的 Django 环境。
