问题:如何在OSX 10.6中将MySQLdb与Python和Django一起使用?
对于OSX 10.6用户,这是一个讨论很多的问题,但是我一直找不到能够解决问题的解决方案。这是我的设置:
Python 2.6.1 64位Django 1.2.1 MySQL 5.1.47 osx10.6 64位
我使用–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,出现以下错误:
Traceback (most recent call last):

我还安装了MySQL for Python适配器,但无济于事(也许我安装不正确?)。
有人处理过吗?
This is a much discussed issue for OSX 10.6 users, but I haven’t been able to find a solution that works. Here’s my setup:
Python 2.6.1 64bit Django 1.2.1 MySQL 5.1.47 osx10.6 64bit
I create a virtualenvwrapper with –no-site-packages, then installed Django. When I activate the virtualenv and run python manage.py syncdb, I get this error:

I’ve also installed the MySQL for Python adapter, but to no avail (maybe I installed it improperly?).
Anyone dealt with this before?

我有同样的错误,pip install MySQL-python
并为我解决了。
备用安装:
- 如果您没有点子,
easy_install MySQL-python
应该可以。 - 如果您的python是由打包系统管理的,则可能必须使用该系统(例如
sudo apt-get install ...
)
下面,Soli指出如果收到以下错误:
EnvironmentError: mysql_config not found
…然后您还有另一个系统依赖性问题。解决方案因系统而异,但对于Debian衍生的系统:
sudo apt-get install python-mysqldb
I had the same error and pip install MySQL-python
solved it for me.
Alternate installs:
- If you don’t have pip,
easy_install MySQL-python
should work. - If your python is managed by a packaging system, you might have to use
that system (e.g.
sudo apt-get install ...
)
Below, Soli notes that if you receive the following error:
EnvironmentError: mysql_config not found
… then you have a further system dependency issue. Solving this will vary from system to system, but for Debian-derived systems:
sudo apt-get install python-mysqldb

如果您没有适当的权限,请不要忘记在命令开头添加“ sudo”。
Adding to other answers, the following helped me finish the installation mysql-python:
virtualenv, mysql-python, pip: anyone know how?

我如何工作的:
virtualenv -p python3.5 env/test
在采购我的环境后:
pip install pymysql
pip install django
然后,我运行了startproject并在manage.py中添加了以下内容:
+ try:
+ import pymysql
+ pymysql.install_as_MySQLdb()
+ except:
+ pass
此外,还更新了此内部设置:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'foobar_db',
'USER': 'foobaruser',
'PASSWORD': 'foobarpwd',
}
}
我也已经configparser==3.5.0
在我的virtualenv中安装了,不确定是否需要…
希望能帮助到你,
How I got it working:
virtualenv -p python3.5 env/test
After sourcing my env:
pip install pymysql
pip install django
Then, I ran the startproject and inside the manage.py, I added this:
+ try:
+ import pymysql
+ pymysql.install_as_MySQLdb()
+ except:
+ pass
Also, updated this inside settings:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'foobar_db',
'USER': 'foobaruser',
'PASSWORD': 'foobarpwd',
}
}
I also have configparser==3.5.0
installed in my virtualenv, not sure if that was required or not…
Hope it helps,

以下对我来说运行64位Ubuntu 13.10的完美工作:
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
实际上,我在另一个问题中找到了解决方案,并在下面引用了它:
如果使用–no-site-packages开关(默认设置)创建了virtualenv,则虚拟环境软件包中不包括系统范围内已安装的附加内容,例如MySQLdb。
您需要使用随virtualenv一起安装的pip命令安装MySQLdb。使用bin / activate脚本激活virtualenv,或者在virtualenv中使用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。唯一的问题是获得等效的安装命令libmysqlclient-dev
,python-dev
因为mysql-python
我猜它们是编译所必需的
。
希望这可以帮助。
The following worked perfectly for me, running Ubuntu 13.10 64-bit:
sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev
Now, navigate to your virtualenv (such as env folder) and execute the following:
sudo ./bin/pip install mysql-python
I actually found the solution in a separate question and I am quoting it below:
If you have created the virtualenv with the –no-site-packages switch (the default), then system-wide installed additions such as MySQLdb are not included in the virtual environment packages.
You need to install MySQLdb with the pip command installed with the virtualenv. Either activate the virtualenv with the bin/activate script, or use bin/pip from within the virtualenv to install the MySQLdb library locally as well.
Alternatively, create a new virtualenv with system site-packages included by using the –system-site-package switch.
I think this should also work with OSX. The only problem would be getting an equivalent command for installing libmysqlclient-dev
and python-dev
as they are needed to compile
mysql-python
I guess.
Hope this helps.

我进行了OSX Mavericks和Pycharm 3的升级,并开始出现此错误,我使用了pip并易于安装,并得到了以下错误:
命令’/ usr / bin / clang’失败,退出状态为1。
所以我需要更新到Xcode 5,然后再次尝试使用pip进行安装。
pip install mysql-python
那解决了所有问题。
I made the upgrade to OSX Mavericks and Pycharm 3 and start to get this error, i used pip and easy install and got the error:

pip install mysql-python
That fix all the problems.

此处引发的错误是在导入python模块中。可以通过将python site-packages文件夹添加到OS X上的环境变量$ PYTHONPATH来解决。因此,我们可以将以下命令添加到.bash_profile文件中:
export PYTHONPATH="$PYTHONPATH:/usr/local/lib/pythonx.x/site-packages/"
*用您正在使用的python版本替换xx
The error raised here is in importing the python module. This can be solved by adding the python site-packages folder to the environment variable $PYTHONPATH on OS X. So we can add the following command to the .bash_profile file:
export PYTHONPATH="$PYTHONPATH:/usr/local/lib/pythonx.x/site-packages/"
*replace x.x with the python version you are using

我在OSX 10.6.6上遇到了相同的问题。但是,只是一个简单easy_install mysql-python
的终端无法解决它,因为随之而来的另一个麻烦是:
error: command 'gcc-4.2' failed with exit status 1
。
显然,从XCode3(OSX 10.6附带提供)升级到XCode4后,就会出现此问题。此较新版本删除了对构建ppc拱的支持。如果相同,请尝试以下操作easy_install mysql-python
sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
rm -r build
python setup.py build
python setup.py install
非常感谢Ned Deily的解决方案。在这里检查
I had the same problem on OSX 10.6.6. But just a simple easy_install mysql-python
on terminal did not solve it as another hiccup followed:
error: command 'gcc-4.2' failed with exit status 1
.
Apparently, this issue arises after upgrading from XCode3 (which is natively shipped with OSX 10.6) to XCode4. This newer ver removes support for building ppc arch. If its the same case, try doing as follows before easy_install mysql-python
sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
rm -r build
python setup.py build
python setup.py install
Many thanks to Ned Deily for this solution. Check here

我遇到了类似的情况,例如您在Mac OS X上的virtualenv中使用python3.7和django 2.1。尝试运行命令:
pip install mysql-python
pip install pymysql
并__init__.py
在您的项目文件夹中编辑文件,并添加以下内容:
import pymysql
pymysql.install_as_MySQLdb()
然后运行:python3 manage.py runserver
或 python manage.py runserver
