mac 部署python环境
Python中最连接Mysql常用的驱动是
mysql-python ：mysql的C语言的驱动
mysql-connector：msql官方的驱动
pymysql：python语言的驱动我这里安装的是 mysql-python
终端中执行
pip install mysql-python运气好的的话，直接就成功了，我遇到了一下问题，最终找到了解决方案，原因及解决方案如下，供参考
问题1：mysql_config not found
终端打印出：
Collecting mysql-python
Downloading MySQL-python-1.2.5.zip (108kB)
100% |████████████████████████████████| 110kB 30kB/s
Complete output from command python setup.py egg_info:
sh: mysql_config: command not found
Traceback (most recent call last): File "<string>", line 20, in <module> File "/private/tmp/pip-build-NP8J3v/mysql-python/ setup.py", line 17, in <module>
metadata, options = get_config() File "setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r") File "setup_posix.py", line 25, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found----------------------------------------Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-NP8J3v/mysql-python解决方法，执行：
ln -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config原因 找不到mysql_config一般是由于通过lnmp.org或者其他方式安装mysql以后mysql_config是在/usr/local/mysql/bin/里面，这里面的文件不是在任意位置都可以访问的，而指令是
将mysql_config链接到/usr/local/bin目录下
参考一条命令解决mysql_config not found
问题2：p_w_picpath not found python
出错信息为：
Traceback (most recent call last): File "manage.py", line 4, in <module> from models import User
File "/Users/tengfei/PycharmProjects/mysql/models.py", line 1, in <module> import MySQLdb File "/Library/Python/2.7/site-packages/MySQLdb/__init__.py", line 19, in <module> import _mysql
ImportError: dlopen(/Library/Python/2.7/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib Referenced from: /Library/Python/2.7/site-packages/_mysql.so
Reason: p_w_picpath not found解决：
pip install --upgrade pip修改 OS X 环境变量：打开终端，在终端中使用 vim 打开 “~/.bash_profile”，如果没有安装 vim，那就显示隐藏文件用文本编辑器打开，具体操作这里就不复述了。在 .bash_profile 中添加以下内容
PATH="/usr/local/mysql/bin:${PATH}"export PATHexport DYLD_LIBRARY_PATH=/usr/local/mysql/lib/export VERSIONER_PYTHON_PREFER_64_BIT=noexport VERSIONER_PYTHON_PREFER_32_BIT=yes其中 VERSIONER_PYTHON_PREFER_64_BIT 和 VERSIONER_PYTHON_PREFER_64_BIT 根据自己安装的 MySQL 进行选择。
参考：

Mac OS + MySQL-python-1.2.3: ImportError | Library not loaded | libmysqlclient.16.dylib
问题3：command 'x86_64-linux-gnu-gcc' failed with exit status 1 异常解决
执行pip install mysql-python后的出错信息如下： 这是在虚拟环境中见到的 ^ compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
----------------------------------------
Command "/home/tengfei/api01/test/TestTo/TODO-orm/venv/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-w6mp1W/mysql-python/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-jG7EKf-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/tengfei/api01/test/TestTo/TODO-orm/venv/include/site/python2.7/mysql-python" failed with error code 1 in /tmp/pip-build-w6mp1W/mysql-python/原因是：一些依赖包没有安装，注意这也是很多实用pip执行安装扩展的时候，常见的错误
apt-get build-dep python-lxml
sudo pip install lxml --upgradepip install mysql-python参考：[Ubuntu/pip] 解决 pip 安装 lxml 出现 x86_64-linux-gnu-gcc 异常
Mac下安装第三方模块报错：‘sqlfront.h‘ file not found的解决办法
1.软件环境：
mac环境：10.11.6（15G31）
python: 3.6
2.问题：
sudo pip install pymssql 后出现下面问题：
fatal error: ‘sqlfront.h‘ file not found
3.解决方案：
终端执行 brew install freetds@0.91
终端执行 brew link --force freetds@0.91
终端执行 sudo pip install pymssql（或则 pycharm直接安装）
