ren*_*nat 61 python mysql macos osx-snow-leopard
试图设置一个干净的Mac OS X 10.6安装来开发python/django,我不记得在10.5上遇到这个问题.
从安装程序安装MySQL后,mysql-5.5.8-osx10.6-x86_64.dmg我跑了
$ sudo pip install MySQL-python
它似乎顺利(下面的输出)

Cleaning up...
在此之后我尝试了:
$ python -c "import MySQLdb"
它在我身上扯了一下:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Library/Python/2.6/site-packages/MySQLdb/__init__.py", line 19, in <module>
import _mysql
ImportError: dlopen(/Library/Python/2.6/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.16.dylib
Referenced from: /Library/Python/2.6/site-packages/_mysql.so
Reason: image not found
我做错了什么？/我还需要做什么？
谷歌搜索(并在此搜索)返回了很多结果,使用Ruby获取此错误消息并不太多.

只需设置DYLD_LIBRARY_PATH运行后pip install或easy_install:
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
应该做的工作假设您的MySQL安装在/usr/local/mysql.

_mysql.so是指libmysqlclient.16.dylib.也就是说,作为Python和MySQL客户端库之间桥梁的共享库_mysql.so引用了MySQL客户端库的动态库,并且由于某种原因无法加载该库.
您需要回答的问题:
libmysqlclient.16.dylib你的系统上有没有？如果没有,则需要安装MySQL客户端软件.DYLD_LIBRARY_PATH设置中包含该库的目录是什么？如果没有,请尝试添加它.libmysqlclient.16.dylib文件没有损坏.我的副本安装在/opt/local/lib/mysql5/mysql/libmysqlclient.16.dylibMacPorts的礼貌中,具有MD5签名c79ee91af08057dfc269ee212915801a,大小为1,462,376字节.你的副本是什么样的？小智 41
在easy_install之后,我创建了一个解决问题的软链接
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib
如果你的MySQL客户端比你的MySQL-python包更新,它也会出现.就我而言,我的机器上有一个libmysqlclient_r.18.dylib,但不是libmysqlclient_r.16.dylib.跑步pip search mysql透露
MySQL-python - MySQL的Python接口安装:1.2.3最新:1.2.3c1
并运行pip install --upgrade MySQL-python修复我的问题.
在最新版本的MySQL 5.7.9上,它没有得到支持MySQL-python,而是使用了PyMySQL库.我还在manage.py(在Django项目中)添加了这些行来模拟MySQL-python的API:
try:
# load MySQLdb interface emulation
import pymysql
pymysql.install_as_MySQLdb()
except ImportError:
pass

在我的设置(来自brew,pyenv的mysql 5.7.x)中,我有一个较新的lib文件libmysqlclient.20.dylib.有用的是pip uninstall MySQL-python和pip install MySQL-python.
