mysql for python 2. 7 says Python v2.7 not found

Question

I have downloaded mysql-connector-python-1.0.7-py2.7.msi from MySQL site and try to install but it gives error that

Python v2.7 not found. We only support Microsoft Windows Installer(MSI) from python.org.

I am using Official Python v 2.7.3 on windows XP SP3 with MySQL esssential5.1.66

Need Help ???

Answer 1

In my case, I installed python 2.7.14 x64 only for my user. I have to look for this in my registry:

HKEY_CURRENT_USER\Software\Python

, export them, open the exported .reg file with a text editor, replace all occurrence of HKEY_CURRENT_USER with HKEY_LOCAL_MACHINE, and import it.

The result is: (remember to change the install dir to yours)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\Software\Python]

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore]

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7]

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\Help]

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\Help\Main Python Documentation]
@="D:\\Desarrollo\\entornos\\python27_x64\\Doc\\python2714.chm"

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\InstallPath]
@="D:\\Desarrollo\\entornos\\python27_x64\\"

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\InstallPath\InstallGroup]
@="Python 2.7"

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\Modules]

[HKEY_LOCAL_MACHINE\Software\Python\PythonCore\2.7\PythonPath]
@="D:\\Desarrollo\\entornos\\python27_x64\\Lib;D:\\Desarrollo\\entornos\\python27_x64\\DLLs;D:\\Desarrollo\\entornos\\python27_x64\\Lib\\lib-tk"

And the installation afterwards is smooth as a breeze. Viola!

Answer 2

You need to make sure that you download the version with the correct "bitness" (32/64 bit), matching the "bitness" of your Python installation!

I ran into the same problem (with Python 3.7.2, though).

I had Python 3.7.2 32 bit already installed, but accidentally downloaded the 64 bit version of the MySQL Connector for Python 3.7.

When I tried to install the connector, I got the same error message:

Solution: I just downloaded the 32 bit version instead, and everything worked (installing the connector and actually connecting to the database)

Answer 3

I met the similar problem under Windows 7 when installing mysql-connector-python-1.0.7-py2.7.msi and mysql-connector-python-1.0.7-py3.2.msi.

After changing from "Install only for yourself" to "Install for all users" when installing Python for windows, the "python 3.2 not found" problem disappear and mysql-connector-python-1.0.7-py3.2.msi was successfully installed.

I guess the problem is that mysql connector installer only looks for HKEY_LOCAL_MACHINE entries, and the things it looks for might be under HKEY_CURRENT_USER etc. So the solution that change the reg table directly also works.

If you're still experiencing this with x64 or other python modules, I'd recommend this website Python Extensions for x64/x32

Answer 5

The Solution I get for this problem is

I have found Adding Python to Registry, the script as follows applicable for python v 2.0 and above: Register a Python Interpreter

#
# 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
#
# source:
# http://www.pythonware.com/products/works/articles/regpy20.htm

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()

Save it with any name. Run it from python interpreter and Thats ALL!!

I solved this problem by using 32bit python
