Caddy tkinter error

Have just got Caddy installed on a new Raspian Pi4 (running version 10, buster), and a Caddyfile configured. This is via a SSH connection using Putty to an IPv6 address.

So far so good. But when I run /etc/caddy/caddy, I get a strange error message from tkinter.

Traceback (most recent call last):
File “/usr/local/bin/caddy”, line 10, in
File “/usr/local/lib/python3.7/dist-packages/caddy/”, line 9, in main
root = tk.Tk()
File “/usr/lib/python3.7/tkinter/”, line 2023, in init = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

Maybe it’s a conflict with the Putty SSH?

But if Caddy is designed to be used from the command line, I’m wondering why a dependency on the Tk GUI toolkit has been included?

Has anyone else seen this behaviour? And found a way round it?

Thanks in advance

Caddy is not a Python tool. It’s written in Go.

Do you have something else installed also called Caddy, written in Python?

yes, my mistake was running this

pip install caddy

what I got from that was not the Caddy webserver!
