获取"加载MySQLdb模块时出错:没有名为MySQLdb的模块" - 尝试过以前发布的解决方案

Question

对于OSX 10.6用户来说,这是一个备受争议的问题,但我找不到有效的解决方案.这是我的设置:

Python 2.6.1 64bit Django 1.2.1 MySQL 5.1.47 osx10.6 64bit

我用--no-site-packages创建了一个virtualenvwrapper,然后安装了Django.当我激活virtualenv并运行python manage.py syncdb时,我收到此错误:

Traceback (most recent call last):
File "manage.py", line 11, in <module>

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

我也安装了MySQL for Python适配器,但无济于事(也许我安装不正确？).

以前有人处理过这个吗？

Answer 1

我有同样的错误并pip install MySQL-python为我解决了.

备用安装:

• 如果你没有pip,easy_install MySQL-python应该工作.
• 如果您的python由打包系统管理,您可能必须使用该系统(例如sudo apt-get install ...)

下面,Soli指出,如果您收到以下错误:

EnvironmentError: mysql_config not found

...那么你还有一个系统依赖问题.解决这个问题因系统而异,但对于Debian派生系统:

sudo apt-get install python-mysqldb

Answer 2

运行Ubuntu,我必须这样做:

sudo apt-get install python-mysqldb

Answer 3

添加到其他答案,以下帮助我完成安装mysql-python:

virtualenv,mysql-python,pip:谁知道怎么样？

在Ubuntu上......

apt-get install libmysqlclient-dev
apt-get install python-dev
pip install mysql-python

如果您没有适当的权限,请不要忘记在命令的开头添加"sudo".

Answer 4

尝试以下命令.他们为我工作:

brew install mysql-connector-c 
pip install MySQL-python

Answer 5

mysql_config必须在路上.在Mac上,做

export PATH=$PATH:/usr/local/mysql/bin/
pip install MySQL-python

Answer 6

pip install mysql-python

提出错误:

EnvironmentError:找不到mysql_config

sudo apt-get install python-mysqldb

解决了这个问题.

Answer 7

我是如何工作的:

virtualenv -p python3.5 env/test

在采购我的环境之后:

pip install pymysql
pip install django

然后,我运行了startproject并在manage.py中,我添加了这个:

+ try:
+     import pymysql
+     pymysql.install_as_MySQLdb()
+ except:
+     pass

另外,更新了这个内部设置:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'foobar_db',
        'USER': 'foobaruser',
        'PASSWORD': 'foobarpwd',
    }
}

我也configparser==3.5.0安装在我的virtualenv中,不确定是否需要...

希望能帮助到你,

Answer 8

以下对我来说非常有效,运行Ubuntu 13.10 64位:

sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev

现在,导航到您的virtualenv(例如env文件夹)并执行以下操作:

sudo ./bin/pip install mysql-python

我实际上在一个单独的问题中找到了解决方案,我在下面引用它:

如果您使用--no-site-packages开关(默认)创建了virtualenv,则虚拟环境包中不包含系统范围的已安装添加项(如MySQLdb).

您需要使用随virtualenv安装的pip命令安装MySQLdb.使用bin/activate脚本激活virtualenv,或者使用virtualenv中的bin/pip在本地安装MySQLdb库.

或者,使用--system-site-package开关创建包含系统站点包的新virtualenv.

我认为这也适用于OSX.唯一的问题是获得一个等效的安装命令libmysqlclient-dev,python-dev因为mysql-python我需要编译它们 .

希望这可以帮助.

Answer 9

试试这个:这解决了我的问题.

pip安装MySQL-python

Answer 10

此问题是MySQL for Python适配器安装不完整/不正确的结果.具体来说,我必须编辑mysql_config文件的路径以指向/ usr/local/mysql/bin/mysql_config - 本文将对此进行更详细的讨论:http://dakrauth.com/blog/entry/python-and- Django的设置-MAC-OS-X-豹/

Answer 11

sudo apt-get install python-mysqldb 在ubuntu中完美运行

pip install mysql-python引发环境错误

Answer 12

这适用于Red Hat Enterprise Linux Server 6.4版

sudo yum install mysql-devel
sudo yum install python-devel
pip install mysql-python
