How to install python-tk in my docker image

问题

I get this error when I run my python script in my docker image

ImportError: No module named _tkinter, please install the python-tk package

So I tried 'pip install python-tk'

root@43d2222b15c8:/tf_files# pip install python-tk
Collecting python-tk
  Could not find a version that satisfies the requirement python-tk (from versions: )
No matching distribution found for python-tk

But that does not fix my issue.

Can you please tell me how can I fix my issue?

Thank you.

回答1:

Use import Tkinter. It should not be required via pip. It's built into python2.7 (Assuming you are using python2.7 since this post is tagged with it. If you are using 3 then it's a different solution and what the people in comments are referencing.)

https://docs.python.org/2/library/tkinter.html#module-Tkinter

It is probably not a problem with the package not being installed but rather not running because of lack of display.

For convenience I'm pasting the code how to do that:

docker run -ti -e DISPLAY=$DISPLAY blah-image blah-command
