Tcl wasn't installed properly

[Steve]

I'm a frequent user of matplotlib on my Windows XP machine. I
recently attempted to install a program that modified my Tcl
installation, and I now get an error message when I attempt to plot
anything in matplotlib. Here is the error message:
---
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python25\lib\lib-tk\Tkinter.py", line 3758, in _test
root = Tk()
File "C:\Python25\lib\lib-tk\Tkinter.py", line 1647, in __init__
self.tk = _tkinter.create(screenName, baseName, className,
interactive, want
objects, useTk, sync, use)
_tkinter.TclError: Can't find a usable init.tcl in the following
directories:
{C:\Program Files\Tcl\lib\tcl8.3} {C:\Program Files\Tcl\lib
\tcl8.3} {C:/Prog
ram Files/Tcl/lib/tcl8.4} C:/Python25/lib/tcl8.4 C:/lib/tcl8.4 C:/
library



This probably means that Tcl wasn't installed properly.

I attempted a complete reinstall of python (hoping it would reinstall
Tcl with correct file paths), but I get the same error. Any
suggestions would be appreciated.
Thanks!

In my installation Tcl is in "C:\Python25\tcl", if that helps.

In my installation Tcl is in "C:\Python25\tcl", if that helps.

That is where my installation is located too. Why is it insisting on
looking in "C:\Python25\lib\tcl8.4"? Can I change where it is looking?

I figured out the solution. The program I installed must have changed
my windows path names. I changed TCL_LIBRARY and TK_LIBRARY to the
location of my tcl installation, and it works fine now.

Please i have similar problem with my cywing, how did you change your TCL_LIBRARY and TK_LIBRARY.

 

[gdalben]

os.environ['TCL_LIBRARY'] = 'C:\Python26\tcl\tcl8.5'
os.environ['TK_LIBRARY'] = 'C:\Python26\tcl\tk8.5'

I faced the same problem during my last installation of ns2.35 in ubuntu 11.04.
After I install ns2.35, got message of successful installation of ns. Then I set path in /.bashrc. Then I gave ns command which gave me same error which you got.

The problem is because, ns executable is also at /usr which is conflicting.

Solution:
1. Go to location root-usr-local-bin by giving following command in terminal
cd /usr/local/bin
2. There you would find the ns file. We just need to remove it by giving following command
rm ns
3. Thats it, you are done. Now your ns starts running successfully.

Happy Learning.....

Than change the order in your $PATH, or better yet, do as below, because
the $PATH is normally ordered to find locally installed stuff first.

Solution:
1. Go to location root-usr-local-bin by giving following command in
terminal cd /usr/local/bin
2. There you would find the ns file. We just need to remove it by giving
following command rm ns
3. Thats it, you are done. Now your ns starts running successfully.
