Dependency problem of ipython 7.16.1-1

Dependency problem of ipython 7.16.1-1

[ggl329]

Hi all,

Recently, I upgraded python36-ipython to 7.16.1-1 and got an error shown below.
The upgraded ipython seems to depend on backcall module (https://github.com/takluyver/backcall).
But cygwin doesn't have python-backcall package.
Is there anyone who will provide python-backcall package?

$ ipython3.6
Traceback (most recent call last):
   File "/usr/bin/ipython3.6", line 5, in <module>
     from IPython import start_ipython
   File "/usr/lib/python3.6/site-packages/IPython/__init__.py", line 56, in <module>
     from .terminal.embed import embed

if you find other problems let us know.
I am aware that "iptest" requires "nose", I am working on it.
