import error with Basemap

Hello,
using the basemap toolkit on Windows with Python 2.5 I get the following import
error:

In [1]: from matplotlib.toolkits.basemap import Basemap

Why does Basemap need any httplib? I am not needing any remote connection.
Any help greatly appreciated.

Thanks and kind regards,
Timmie

Timmie: Did you install basemap from source or using the binary installer?

Because it includes a module for reading remote datasets over http.

Basemap includes the httplib2 module (http://code.google.com/p/httplib2/), but if you're installing from source it will only install it if it thinks you don't already have it. The simple workaround is to grab it and install it yourself (it's a single file, pure-python module).

If you've used the binary installer, it should definitely have been installed - so if that's the case let me know and I'll investigate further.

I used the binary installer for windows that you can download from Sourceforge.net

In fact, the thing is strange: I developed a program which displays a map at the end. A simple one but it worked. I didn't use it for some time. Today I used it again and: it didn't for anymore. I only got that strange error.

May I have a module conflict?

Please tell be if you need more information.

Kind regards & thanks for your quick response.

Timmie: It's possible that the windows installer is missing the httplib2 module - I don't have access to windows right now to check. Could you try installing httplib2 and let me know if that fixes it?
