在python中进行安装mysql模块，但是怎么都不能导入mysql模块，出错如下所示：
[python] view plain copy
-
[root@python ~]# python
-
Python 2.7.11 (default, Apr 5 2016, 12:24:31)
-
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
-
Type "help", "copyright", "credits" or "license" for more information.
-
>>> import MySQLdb
-
Traceback (most recent call last):
-
File "<stdin>", line 1, in <module>
-
ImportError: No module named MySQLdb
检查安装包：
[python] view plain copy
-
[root@python ~]# rpm -qa MySQL-python
-
MySQL-python-1.2.3-0.3.c1.1.el6.x86_64
发现在操作系统中已经安装了Mysql-python的包，但是依然不能导入的。。。
安装mysql-python模块：
[python] view plain copy
-
error: command 'gcc' failed with exit status 1
-
-
----------------------------------------
-
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-OcAYDJ/mysql-python/setup.py';
-
exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))"
-
install --record /tmp/pip-Urb3hW-record/install-record.txt --single-version-externally-managed --compile"
-
failed with error code 1 in /tmp/pip-build-OcAYDJ/mysql-python/
在进行pip jinstall musql-python的时候就是出错！！！报错内容如上。
出错的原因是因为必须安装mysql-python包，从而安装此包：
[python] view plain copy
-
[root@python ~]# yum -y install mysql-devel
再次进行安装mysql-python模块：
[python] view plain copy
-
[root@python ~]# pip install mysql-python
-
Collecting mysql-python
-
Using cached MySQL-python-1.2.5.zip
-
Installing collected packages: mysql-python
-
Running setup.py install for mysql-python ... done
-
Successfully installed mysql-python-1.2.5
成功安装。
在使用pip安装的模块的时候，如果需要卸载，那么只要pip uninstall packagename即可，还是蛮方便的。
此问题在2.7版本中发现，在2.6版本中仅仅需要安装mysql-python包即可导入。
