Mac OS 10.6.2 Snow Leopard上的Django + MySQL

Question

这个问题已经有了一些很好的答案，然而，它们现在已经过时了。

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

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

 ^CiMac:segisys drhoden$ 

同样，从python shell：

iMac:myproject drhoden$ python
Python 2.6.4 (r264:75821M, Oct 27 2009, 19:48:32)

>>> import MySQLdb

  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。

我最终解决了我自己的问题，当然，我读过的许多帖子，博客和邮件日志中的潜意识和有意识的帮助。 如果我记得，我会给出链接。

简而言之，我使用MacPorts重新安装了一切。

编辑〜/ .bash_profile并注释掉所有以前对$ {PATH}的修改后，我下载了Snow Leopard的dmg并完成了它的安装。

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，永远。 但是当它完成时它提示我以下内容：

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

sudo port install python_select  
sudo python_select python26

我做了两个，他们走得很快。

我忘了提一下方便的'端口搜索'命令。 我搜索了'mysql'，类似于在'install'之后找到要输入的东西。 但我继续为MySQL重新安装客户端和服务器。 也许我以相反的顺序做了这个，但最终的结果很好。

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安装程序如何为您提供有关下一步操作的反馈。 在服务器安装结束时，它说：

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

这对我来说是一个新的安装（没有任何本地架构）。 为了完整性，我自己参考，这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!

几乎完成了。 在我的“端口搜索”早期，我遇到了这个有趣的端口：

py26-mysql @ 1.2.2（python，devel，databases）Python接口到mysql

非常希望这能为我提供MySQLdb包，我安装了它（它确实如此）。

sudo port install py26-mysql

后来我开始使用python解释器试图导入My​​SQLdb，这是我一直以来的方式。

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

>>> 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，但它工作!!

还有一件事：

sudo port install py26-django

在完成所有这些之后，我终于能够启动我的Django项目并远程连接到我公司的MySQL服务器！ 可能没有必要使用MacPorts重新安装Django，但我不会冒险并发症。

Answer 2

几个月前，我在Snow Leopard上成功安装了MySQL之后写了一篇博文：

http://jboxer.com/2009/09/installing-mysql-on-snow-leopard/

如果你按照这些步骤，它（理论上）应该解决你的问题（这听起来像是由32位和64位软件混合引起的）。

顺便说一下，我不是想在这里自我推销; 博客文章中的文字基本上就是我在这里发布的内容，我正在尝试将DRY应用到我生活中的更多领域:)

Answer 3

当您使用32位和64位混合软件时会发生这种情况。

基本上，对于Snow Leopard，你需要安装MySQL 64bit软件包（它仍然被列为10.5，但这没有问题），之后再次轻松安装python-mysql。 一切都会奏效。
