djang中出现“No module name mysqldb”错误

Question

我已经用mysql数据库引擎在ubantu14.04上安装了django1.7（python2.7.6），但是运行命令-

python manage.py migrate

我正处于错误之下

我试过用命令安装mysqldb

pip install MySQL-python

那我就要低于错误了

^{pr2}$

我的设置.py文件是

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

Answer 1

您有两个选项，如下所述：

分发包为-：

sudo apt-get install python-mysqldb

在这种情况下，您不能使用virtualenv no site packages（默认选项），但必须使用：

virtualenv system-site-packages myenv

使用clean virtualenv并构建自己的pythonmysql包。在

首先创建virtualenv：

virtualenv myvirtualenv

source myvirtualenv/bin/activate

然后安装生成依赖项：

sudo apt-get build-dep python-mysqldb

现在可以安装python mysql了

pip install mysql-python

注意Ubuntu包是python mysqldb，python pypi包是python mysql（不带db）

Answer 2

在上面的例子中，答案可能在正确的日志文件pip.log或/tmp/pip-build-rHe_Sb/MySQL-python中的某个地方。在

1）使用PIP安装MySQL模块时，请确保您在系统中安装了mysql-devel（yum）或libmysqlclient-dev（apt get）包。在

2）顺便说一句，我建议使用mysqlclient（$ pip install mysqlclient），而不是{}，因为它同时支持python2和3.x
