Why do I get easy_install error “'NoneType' object has no attribute 'clone'”?

Question

I'm trying to run the command:

easy_install MySQLdb

But, I'm getting the error:

'NoneType' object has no attribute 'clone'

I'm using Windows 7 x64 with Python 2.6 x86 (I've tried Python x64, but I get the same error). I'm also using setuptools 0.6c11 (only available in 32-bit).

Please see the full error on Pastebin.

Answer 1

There seems to only be an egg for Python 2.5 on Windows. Try with Python 2.5 on Windows for now, and it should work, yet I agree having two versions of Python can really put you in a horrible situation sometimes. Also, the package is MySQL-python and not MySQLdb.

See this other answered SU question for a workaround to get it on Python 2.6

Answer 2

The package is called MySQL-python. Before barfing up the Traceback, python output:

Creating /Users/fideli/py2.6/lib/python2.6/site-packages/site.py
Searching for MySQLdb
Reading http://pypi.python.org/simple/MySQLdb/
Couldn't find index page for 'MySQLdb' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading http://pypi.python.org/simple/
No local packages or download links found for MySQLdb
Best match: None

Try easy_install MySQL-python instead.

Ah, looks like the error is caused because MySQLdb does not exist. They need a better error message I think. Furthermore, to use setup.py install on windows, we need to install the "Developer Components" during the MySQL server setup, and I think we must use MySQL 5.0 but I'm not sure.
