你安装了mysqlclient吗？

Question

我已经阅读了每一篇文章，并在过去的 4 个小时里用谷歌搜索，试图找到解决这个错误的方法。

我没有运行虚拟环境，该服务器仅用于 django。
服务器：Ubuntu 16.04
蟒蛇：3.5.2

我收到此错误

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

尝试安装 mysqlclient

sudo -H pip3 install mysqlclient
Requirement already satisfied: mysqlclient in /usr/local/lib/python3.5/dist-packages (1.3.12)

使用 ubuntu

sudo apt-get install -y python3-mysqldb
Reading package lists... Done

python3-mysqldb is already the newest version (1.3.7-1build2).

任何帮助是极大的赞赏

Answer 1

MySQL 客户端未正确安装。为此，该模块没有找到。那么为什么它返回此错误消息。波纹管我的实际代码，我解决了这个问题。希望你的。

转到您的命令终端并键入 [基于操作系统（Windows、Mac Os、Linux）]

你可以升级 setuptools 包如果没有更新

pip install --upgrade setuptools

然后安装python mysql

pip install pymysql

然后编辑项目根目录中的init .py 文件（settings.py 文件所在的位置）

import pymysql
pymysql.install_as_MySQLdb()

编辑根目录下的 settings.py 文件：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'database name',
        'USER': 'username',
        'PASSWORD': 'password',
        'HOST': '127.0.0.1',  // If localhost
        'PORT': '3306',  // your database running port
    }
}

就是这样。我希望，我能帮到你。如果有任何问题，请评论我。

有时你在尝试安装 mysqlclient 时遇到此类型错误

您安装了 pymysql 但没有任何效果，请尝试以下命令

     sudo apt-get install python3-dev default-libmysqlclient-dev build-essential #for debin

安装后然后运行

 pip install mysqlclient
