Eclipse PyDev now shows all references to Tkinter as errors

问题

I've been using Eclipse with PyDev (on Windows, mind you) for my Python Tkinter project for about a month now, and up until recently I've had no complaints. I start the source for one module (my GUI) like so:

from Tkinter import *

Now, ever since I updated Eclipse to 3.6.1, it shows an error for every call to the Tkinter module(Frame(), Label(), Tk(), etc.). I thought that something might have gone wrong during the update, so I uninstalled Eclipse, re-downloaded it (Eclipse 3.6.1 Classic), and reinstalled it. Then, seeing that that gave me a bunch of errors with installing PyDev, I removed that, got Eclipse 3.6.0 Classic, installed it, and got the same problem I was trying to fix earlier.

I don't understand what's wrong here. It doesn't make any sense to me why all of a sudden Eclipse would stop recognizing that I had imported Tkinter.

Can anyone offer any suggestions/input? I really want to stick with Eclipse, I'm very happy with it, but I can't deal with it giving me about 200 bogus errors.

You really shouldn't use wild imports. Consider from Tkinter import Frame, Label or import Tkinter as tk instead.

Now to your problem: I have Eclipse Helios, too (3.6.0.v20100602). The problem you describe clearly has to do with PyDev, not with the Eclipse base project. I just tried the same import and didn't get error messages. My PyDev version also retrieves the docstring of Frame correctly, for example.

I think it boils to just installing a newer version of PyDev (this is the solution for many bugs ^^) - add "http://pydev.org/nightly" as an update site and then upgrade to the latest version. I have version 1.6.3.20100922, by the way. If that doesn't help, you should consider reporting it as a bug.

I find the answer to problems like this is usually that you have to update your pythonpath from eclipse. See my answer to a similar question. I think re-installing pydev and/or eclipse usually solves this problem because in doing so, the pythonpath is re-configured.

Which Python version do You use? If > 3.1 try (note lowercase writing):

from tkinter import *
