Mac OS 10.6.2 Snow Leopard上的Django + MySQL

django

对于这个问题已经有了一些很好的答案，但是现在它们已经过时了。

我已经能够安装模块，但是“ python manage.py runserver”失败，

 iMac:myproject drhoden$ python manage.py runserver
 Validating models...
 Unhandled exception in thread started by <function inner_run at 0x10496f0>

 django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dynamic module does not define init function (init_mysql)

 ^CiMac:segisys drhoden$

同样，从python shell：

iMac:myproject drhoden$ python
Python 2.6.4 (r264:75821M, Oct 27 2009, 19:48:32) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

>>> import MySQLdb

  File "build/bdist.macosx-10.3-fat/egg/MySQLdb/__init__.py", line 19, in <module>

  File "build/bdist.macosx-10.3-fat/egg/_mysql.py", line 7, in <module>
  File "build/bdist.macosx-10.3-fat/egg/_mysql.py", line 6, in __bootstrap__
ImportError: dynamic module does not define init function (init_mysql)
>>>

使用MySQL-python-1.2.3c1和setuptools-0.6c11-py2.6.egg

任何帮助，将不胜感激。

我最终解决了自己的问题，当然，我从许多已读过的帖子，博客和邮件日志中获得了潜意识和有意识的帮助。如果我记得的话，我会提供链接。

简而言之，我使用MacPorts重新安装了一切。

编辑〜/ .bash_profile并注释掉对$ {PATH}的所有先前修改之后，我下载了Snow Leopard的dmg并完成了安装过程。

然后打开终端并运行自我更新。

sudo port selfupdate
sudo port install python26

第二部分，安装Python 2.6，花费了很多时间。但是完成后，提示我以下内容：

To fully complete your installation and make python 2.6 the default, please run

sudo port install python_select  
sudo python_select python26

我都做了，他们很快就完成了。

我忘了提一下“端口搜索”命令有多方便。我搜索了“ mysql”，并且类似地找到了“安装”后要键入的内容。但是我着手重新安装MySQL的客户端和服务器。也许我以相反的顺序进行了操作，但是最终结果还是不错的。

sudo port install mysql5
...
--->  Installing mysql5 @5.1.41_0
The MySQL client has been installed.
If you also want a MySQL server, install the mysql5-server port.

很自然地：

sudo port install mysql5-server

我喜欢这么多的Macports安装如何为你提供有关下一步操作的反馈。在服务器安装结束时，它显示以下内容：

******************************************************
* In order to setup the database, you might want to run
* sudo -u _mysql mysql_install_db5
* if this is a new install
******************************************************

对我来说，这是一个新安装（没有任何本地模式）。为了完整起见，以供我参考，以下是运行该命令的输出：

Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql5/bin/mysqladmin -u root -h iMac.local password 'new-password'

Alternatively you can run:
/opt/local/lib/mysql5/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql5/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /opt/local/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /opt/local/lib/mysql5/bin/mysqlbug script!

快完成了在“端口搜索”的早期，我遇到了一个有趣的端口：

py26-mysql @ 1.2.2（python，devel，数据库）mysql的Python接口

非常希望这会为我提供MySQLdb软件包，我安装了它（确实做到了）。

sudo port install py26-mysql

余言之后，我加速了python解释器的尝试，以导入MySQLdb，这一直都是我的方式。

iMac:~ drhoden$ python
Python 2.6.4 (r264:75706, Dec 15 2009, 18:00:14) 
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/MySQLdb/__init__.py:34: DeprecationWarning: the sets module is deprecated from sets import ImmutableSet
>>>

警告，但是有效！！

还有一件事：

sudo port install py26-django

完成所有这些工作之后，我终于能够启动Django项目并远程连接到公司的MySQL服务器！也许没有必要使用MacPorts重新安装Django，但是我并不会冒任何麻烦。
