Question

我已经尝试了很多来解决这个问题，但我没有解决它。我在谷歌和stackoverflow上搜索了很多，没有选项对我有用。请帮我。提前致谢。我使用的是django 1.10，python 3.4。我试过了：

pip install mysqldb。
pip install mysql。
pip install mysql-python。
pip install MySQL-python。
easy_install mysql-python。
easy_install MySQL-python。

还剩下什么？

Answer 1

MySQLdb是MySQL数据库的接口。正如其他帖子所提到的，MySQLdb不支持Python 3.x.我使用PyMySQL作为替代品。您需要先安装它：

pip install PyMySQL

下一步是在所有代码中用'pymysql'替换'MySQLdb'，这是令人生畏的。幸运的是，PyMySQL可以作为MySQLdb动态加载。为了在Django中实现它，你需要在项目的默认应用程序的目录下的__init__.py文件中添加以下行（如果你有一个名为'myproject'的项目，添加到myproject / myproject / init.py的行）：

import pymysql
pymysql.install_as_MySQLdb()

运行Django项目时会执行__init__.py，MySQLdb将被替换。然后你的问题就解决了。

Answer 2

MySQLdb仅适用于Python 2.x.您无法在Python 3.x版本中安装。现在从你的问题我可以看到你正在使用Django。在这种情况下，您有三种选择，来自Django mysql notes：

mysqldb
的mysqlclient
的MySQL-CONNECT-蟒

这给你两个选择，mysqlclient和mysql-connect-python，第一个需要从插件的扩展编译，在Windows中，这意味着VStudio库和编译原生扩展的专有技术。

没有编译mysql-connect-python（我不建议将其用于生产，也许只适用于开发），因此您需要安装它。

您可以尝试：

<p id="instructions">Click and drag either div to see automatic arrow adjustments.</p>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.0/jquery-ui.min.js"></script>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%">
  <defs>
    <marker id="arrowhead" viewBox="0 0 10 10" refX="3" refY="5"
        markerWidth="6" markerHeight="6" orient="auto">
      <path d="M 0 0 L 10 5 L 0 10 z" />
    </marker>
  </defs>
  <g fill="none" stroke="black" stroke-width="2" marker-end="url(#arrowhead)">
    <path id="arrowLeft"/>
    <path id="arrowRight"/>
  </g>
</svg>
<div id="a">Div 1</div>
<div id="b">Div 2</div>

或

pip3 install mysql-connect-python

如果第一个失败。

Answer 3

您可以使用 mysqlclient 代替MySQLdb。 MySqLdb与Python 3不兼容。

pip install mysqlclient

Answer 4

MySQLdb与Python 3不兼容。使用mysql-client或mysql-connect。

Answer 5

您也可以尝试直接从源代码安装 mysqlclient-python ：

通过git clone或zipfile下载源代码（网址 - https://github.com/PyMySQL/mysqlclient-python.git）。
自定义site.cfg（您可以提供 mysql_config 的路径）
python setup.py install

Answer 6

在Windows上将此软件包用于python 2.7 http://www.codegood.com/archives/129

Answer 7

MySQLdb不适用于Python 3.x

我有CentOS服务器

这对我有用

python3 -m pip install --user https://github.com/davispuh/MySQL-for-Python-3/archive/1.0.tar.gz

.AddCommand()

加载MySQLdb模块时出错：没有名为＆＃39; MySQLdb＆＃39;
