[Paraview-developers] Paraview runtime tcl error: Can't find a usable init.tcl

[Prashant V]

Hi,



I am new to Paraview and developing a paraview plugin. From plugin, I am executing a python script using pqPythonManager.

        pqPythonManager *pm = pqPVApplicationCore::instance()->pythonManager();
        pm->executeScript("button.py");



>From script, I am trying to create gui button. Scripy snippet is below:



        import os
        import sys
        import Tkinter
        import tkMessageBox



        top = Tkinter.Tk()

        def helloCallBack():
           tkMessageBox.showinfo( "Hello Python", "Hello World")



        B = Tkinter.Button(top, text ="Hello", command = helloCallBack)

        B.pack()
        top.mainloop()



During run, I am getting below error (at top = Tkinter.Tk())



----------------------------------------------------

Traceback (most recent call last):
  File "<string>", line 6, in <module>
  File "<install-dir>/bin/Python/lib/python2.7/lib-tk/Tkinter.py", line 1764, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable init.tcl in the following directories:
    /opt/anaconda1anaconda2anaconda3/lib/tcl8.5 <install-dir>/paraview/lib/lib/tcl8.5 <install-dir>/paraview/lib/tcl8.5 <install-dir>/paraview/lib/library <install-dir>/paraview/library <install-dir>/paraview/tcl8.5.15/library <install-dir>/paraview/tcl8.5.15/library



This probably means that Tcl wasn't installed properly.

-----------------------------------------------



I could find init.tcl in directory <install-dir>/bin/Python/lib/python2.7/lib/tcl8.5, where system is not looking for.



Can somebody please help with this error? Do I need to set tcl path somewhere?

Thanks a lot in advance.
