  • 在Win7中使用Python的MySQLdb模块

    概述:

      Linux上对这一块的处理还是不错的,不过在Windows上就有一点小麻烦,麻烦的点不在于安装过程,而是在安装的过程中可能会有一些问题。


    步骤:

    1.安装MySQLdb模块

      我们在网上下载相应的MySQLdb的版本文件,例如我的就是MySQL-python-1.2.3.win-amd64-py2.7。此文件是exe文件,直接点击运行即可。


    2.解决python version 2.7 required,which was not found in the registry报错


      在我想下载完MySQL-python-1.2.3.win-amd64-py2.7.exe进行安装时,程序给我报了这样一个错误信息:



      原因分析:

      win7是64位的原因,在安装python时,如果选择只为当前用户,以上问题是不会出现的,如果选择所有用户,那就用上面的方法解决吧


      解决方法:

      1.复制下面的代码,保存至register.py:

    #
    # 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.运行register.py,搞定。


    3.解决DLL load failed: %1 不是有效的 Win32 应用程序报错


      出现上述问题的原因是因为我们的Python和MySQLdb的版本不对应造成的。我的问题是Python是32位的,而MySQLdb却是64位的。
