Python： 將TXT文件寫入MySQL

當前環境：

• Windwos 10
• Python 2.7
• MySQL 5.5
• PyCharm

遇到的問題

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

   pip install MySQLdb

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

安裝MySQLdb時，報錯缺乏Visual C++ 9.0。解決方法：下載並安裝MySQL-python 1.2.5 . https://pypi.python.org/pypi/MySQL-python/1.2.5

注意: 64位系統的，請安裝64位的，不然報錯

3. 安裝MySQL-python時報錯：Python version 2.7 required, which was not found in the registry
   緣由： 這是在註冊表不能識別python2.7,緣由windows是64位，安裝的python是32位
   解決方法：
   1.在任意盤符文件夾新建一個register.py文件， 將以下代碼拷貝進去:

   #
   # 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.  定位到該文件所在目錄，運行python register.py 。提示 Python 2.7 is now registered! 表示成功。 繼續執行MySQL-python便可。
