IOError: [Errno 32] Broken pipe

When I do :Tandem there are no new :messages. :TandemSession prints Session ID: None and editing the buffer will crash with the following error:

error caught in async handler '/home/zaab/.config/nvim/bundle/nvim/rplugin/python/tandem_neovim.py:autocmd:TextChangedI:* ()'

:CheckHealth is perfect and I have python2, python3, nodejs and their neovim packages.

Let me know if you need more information :)

Thanks for trying Tandem @Zaab1t!

Are there any log files in your /tmp directory of the form tandem-*.log? If so, could you paste them here so we could take a look?

[carlbordum]

There are none. I tried "hosting" and connecting to another user, but it didn't spawn any log files.

[geoffxy]

Hmm, alright. What does your shell return when you run which python3? Also what version of Python 3 do you have?

[carlbordum]

/usr/bin/python3

Python 3.5.2

Also tried setting let g:python3_host_prog = $HOME . '/usr/bin/python3' before anything in my config, but that didn't help.

I have the same issue. I added

and it prints None in vim. I have python3==3.5.2, and neovim==0.2.4 and python3-neovim==0.2.4. The paths and versions reported by nvim +CheckHealth are correct. The only health warning is a missing Ruby provider (irrelevant). I have no log files in /tmp or elsewhere that I could find. I am running on Mint/Ubuntu 16.04 (and xmonad, if relevant, but I doubt it).

Would love to try this software! Let me know if there is anything that I can do to help debug this.

[carlbordum]

That is odd. I have the same health warning, os (Ubuntu, not mint) and I also run xmonad.
