Why is Pydev in Eclipse claiming errors on a working program? [duplicate]

Eclipse PyDev now shows all references to Tkinter as errors

I have the very simple test project:

from Tkinter import *

win = Tk()
l = Label(win, text="Hello, TKInter")
l.pack()

win.mainloop()

It runs fine, but in Eclipse, I get the following two errors:

Undefined variable: Label line 3
Undefined variable: Tk line 2

Am I doing something to generate these errors? If not, is there a way to force Eclipse to re-evalu开发者_运维百科ate those lines correctly?

Because you import *. Eclipse hence don't know that Tk and Label is imported. Use from Tkinter import Tk, Label instead.
