If I start python3 and do: ------------------------------------------------------- $ python3 Python 3.4.3 (default, Oct 9 2015, 22:53:58) [GCC 4.9.3] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import tkinter >>> root = tkinter.Tk() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/gnu/store/y5x6c38fzrbfl80jxrgjd6py2k88x12a-python-3.4.3/lib/python3.4/tkinter/__init__.py", line 1851, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: Can't find a usable tk.tcl in the following directories: /gnu/store/sd4fcdk9yzh1s0230fjx1yfwk9pl71bf-tcl-8.6.4/lib/tcl8.6/tk8.6 /gnu/store/sd4fcdk9yzh1s0230fjx1yfwk9pl71bf-tcl-8.6.4/lib/tk8.6 /gnu/store/y5x6c38fzrbfl80jxrgjd6py2k88x12a-python-3.4.3/lib/tk8.6 /gnu/store/lib/tk8.6 /gnu/store/y5x6c38fzrbfl80jxrgjd6py2k88x12a-python-3.4.3/library
This probably means that tk wasn't installed properly. ------------------------------------------------------- Did you successfully test it? Regards, Fede
