mysql for python 2. 7说没有找到Python v2.7

Question

我从MySQL站点下载了mysql-connector-python-1.0.7-py2.7.msi并尝试安装,但它给出了错误

找不到Python v2.7.我们只支持python.org上的Microsoft Windows Installer(MSI).

我使用MySQL esssential5.1.66在Windows XP SP3上使用官方Python v 2.7.3

需要帮忙 ？？？

Answer 1

我安装时,在Windows 7下遇到了类似的问题mysql-connector-python-1.0.7-py2.7.msi和mysql-connector-python-1.0.7-py3.2.msi.

从更改"Install only for yourself"为"Install for all users"安装Python for Windows时,"python 3.2 not found"问题消失并mysql-connector-python-1.0.7-py3.2.msi成功安装.

我想问题是mysql连接器安装程序只查找HKEY_LOCAL_MACHINE条目,它查找的东西可能在HKEY_CURRENT_USER等等.所以直接更改reg表的解决方案也可以.

我遇到这个问题的解决方案是

我发现将Python添加到Registry,适用于python v 2.0及更高版本的脚本如下:注册Python解释器

#
# script to register Python 2.0 or later for use with win32all 
# and other extensions that require Python registry settings
#
# written by Joakim Low for Secret Labs AB / PythonWare

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_LOCAL_MACHINE, regpath)
    except EnvironmentError:
        try:
            reg = CreateKey(HKEY_LOCAL_MACHINE, 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()

用任何名字保存.从python解释器运行它,并且全部!

这个问题主要是64位窗口.在此链接http://www.codegood.com/archives/129下载MySQL for python 64位并下载 MySQL-python-1.2.3.win-amd64-py2.7.exe(1.0 MiB) 这将安装MySQL for蟒蛇.

Windows 10(64位):
确实,我遇到了类似的问题,无法为MySQL安装python 2.7连接器.

在此之前我安装Python 2.7.15了Windows x86-64 MSI installer,
这是我Python 3在我的机器上安装的时候.

该Windows x86 MSI installer做的伎俩,我已经安装了它覆盖的Python 2.7.15之前的版本,然后安装在连接器(这一次没有给出错误消息).

然后重新检查MySQL安装程序中的状态并发表声明:
