ZODB 3用于64位窗口

Question

I tried to install ZODB3 for 64 bit Python 2.7 with pip. This installation requires a local compiler to compile the BTrees extension. As I do not have the needed MS compiler installed:

• Is there a binary 64 bit Windows installer for ZODB on Python 2.7 ? I used Google but did not succeed
• Is BTrees really required or can I install ZODB3 without BTrees ?

Cherrs, Uwe.

Answer 1

The ZODB3 package comes with pre-compiled eggs for Windows, see the PyPI page for ZODB3 .

You need to tell pip explicitly that it needs to install an egg; it normally does not support installing from an egg:

pip install --egg ZODB3

Alternatively, you could use easy_install instead.

Answer 2

Struggling with ZODB3 easy_install/pip/compiler woes on Windows? Try Christoph Gohlke's "Unofficial Windows Binaries for Python Extension Packages" download page:

• 64 and 32 bit ZODB3 binaries packaged as .exe installers are available for python 2.5/2.6/2.7: http://www.lfd.uci.edu/~gohlke/pythonlibs/#zodb3

• You will need to run the appropriate zope.interface installer from the same source first: http://www.lfd.uci.edu/~gohlke/pythonlibs/#Zope.interface
