使用easy_install安装
sudo easy_install MySQL-python
报错信息中有这两行,没有mysql_config命令
sh: mysql_config: command not found
EnvironmentError: mysql_config not found
先找下这个命令在哪里,查到是mysql/bin下命令。难道mysql没有添加到我的环境变量path中。
检查下path,可能是没有配置这个命令
$ echo $PATH
/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/bin:
/usr/local/bin:
/usr/bin:
/bin:
/usr/sbin:
/sbin:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc:
/Users/chopin/apache-maven-3.3.9/bin:
确实没有配置,知道了这个问题解决起来就好办了。
解决方法
添加一个软链接,将命令放到环境变量/usr/local/bin下
ln -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config
然后再执行安装命令
$sudo easy_install MySQL-python

看到安装提示有16个警告,安装的版本是1.2.5
检测安装是否成功
使用help()方法来检测模块是否安装。
$ python

>>> help()
//输入模块名
help> MySQLdb
problem in MySQLdb - <type 'exceptions.ImportError'>: dlopen(/Users/chopin/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.10-intel.egg-tmp/_mysql.so, 2):

Referenced from: /Users/chopin/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.10-intel.egg-tmp/_mysql.so
Reason: image not found
又发现了错误,Library not loaded: libmysqlclient.18.dylib
找不到libmysqlclient.18.dylib这个库文件。
实际上这个文件在/usr/local/mysql/lib下的,所以又是文件路径引用错误。
再次做个软链接
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib
再次在help下输入模块名MySQLdb,会输出说明文档,帮组熟悉模块内容。
help> MySQLdb

好了,大功告成,可以尽情的开发了。
