• Windwos 10
• Python 2.7
• MySQL 5.5
• PyCharm

遇到的问题

1. ImportError: No module named MySQLdb
   安装MySQLdb, 注意是windows命令符下，不是python环境下

   pip install MySQLdb

2. error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27

安装MySQLdb时，报错缺少Visual C++ 9.0。解决方法：下载并安装MySQL-python 1.2.5 . https://pypi.python.org/pypi/MySQL-python/1.2.5

注意: 64位系统的，请安装64位的，否则报错

3. 安装MySQL-python时报错：Python version 2.7 required, which was not found in the registry
   原因： 这是在注册表不能识别python2.7,原因windows是64位，安装的python是32位
   解决方法：
   1.在任意盘符文件夹新建一个register.py文件， 将如下代码拷贝进去:

   
   #
   # script to register Python 2.0 or later for use with win32all
   # and other extensions that require Python registry settings
   #

import sys

from _winreg import *

tweak as necessary

version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\Python\Pythoncore\%s\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\Lib\;%s\DLLs\" % (
installpath, installpath, installpath
)

def RegisterPy():
try:
reg = OpenKey(HKEY_CURRENT_USER, regpath)
except EnvironmentError as e:
try:
reg = CreateKey(HKEY_CURRENT_USER, regpath)
SetValue(reg, installkey, REG_SZ, installpath)
SetValue(reg, pythonkey, REG_SZ, pythonpath)
CloseKey(reg)
except:
print " Unable to register!"
return
print "--- Python", version, "is now registered!"
return
if (QueryValue(reg, installkey) == installpath and
QueryValue(reg, pythonkey) == pythonpath):
CloseKey(reg)
print "=== Python", version, "is already registered!"
return
CloseKey(reg)
print "Unable to register!"
print "*** You probably have another Python installation!"

if name== "main":
RegisterPy()

2.  定位到该文件所在目录，运行python register.py 。提示 Python 2.7 is now registered! 表示成功。 继续执行MySQL-python即可。
