click.echo() and click.secho() failed under ipython notebook

[berniey]

I am using ipython notebook to run some of the terminal based code I wrote and found click.echo() and click.secho() will failed...

Any suggestion for a quick fix?

import click
click.echo('hello')

Any suggestions? I'm hitting the same issue.

This is a bug that was fixed in ipython. A workaround is on click master.

I'm having the same problem... I'm using Jupyter-notebook, python 3.5.

 258     if message:
 259         file.write(message)
 260     file.flush()

I believe this is causing issues ielsewhere:

Last "click" release according to https://github.com/pallets/click/releases was before fixing this issue
When do you plan next release with this fix so that installing with python pip will download release with this problem resolved?

In the meantime, the workaround is: pip install git+https://github.com/pallets/click. Be sure to do this in a virtualenv.
