我正在关注django教程，很多人都提出了这个问题，但我认为我的情况有点独特，因为在安装python-mysql后，当我尝试做python manage.py syncdb时，我仍然会收到此错误，
我在virtualenv，因为我使用macports来管理我的python安装我创建了我的virtualenv
virtualenv code/vdjango --no-site-packages --python=/opt/local/bin/python
在使用macports之前我安装了django py27-django，但在创建了virtualenv之后，我认为将django安装到virtualenv上更好，所以我使用了pip install django==1.5
根据django教程，我编辑了我的settings.py文件，然后执行python manage.py syncdb，最后出现以下错误：
[~/code/vdjango/newsite]$python manage.py syncdb
Traceback (most recent call last):

为了确认我已经安装了python-mysql包，我再次运行了pip install，
(vdjango)mac-pro@localhost:[~/code/vdjango/newsite]$pip install python-mysqldb
Downloading/unpacking python-mysqldb
Could not find any downloads that satisfy the requirement python-mysqldb
No distributions at all found for python-mysqldb
Storing complete log in /Users/mac-pro/.pip/pip.log
所以这里发生了什么？看起来我已经拥有了我需要进一步完成教程的所有内容，但有些python / django抱怨没有mysqldb。
答案 0 :(得分：18)
我的libmysqlclient.18.dylib位于/ usr / local / mysql / lib /中，但我的系统在/ usr / lib /中查找它。我最终在/ usr / lib中创建了libmysqlclient.18.dylib的符号链接来修复问题。
打开你的shell。
sudo -s
ls /usr/local/mysql/lib/ | grep libmysqlclient.18.dylib
你应该看到文件：
libmysqlclient.18.dylib
如果没有，请在系统中搜索文件的位置：
find / -name libmysqlclient.18.dylib
在shell中输入以下命令：
ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
如果您的libmysqlclient.18.dylib文件不在/ usr / local / mysql / lib中，请使用libmysqlclient.18.dylib的正确路径替换第一个路径。
希望这有帮助。
