I'm having the same issue entering INSERT mode.

Yep, same problem here, just after entering insert mode too.

It is already known issue.
Please use https://github.com/Shougo/deoplete.nvim/pull/1070 instead.

[Shougo]

Fixed by #1070.

[lewisdiamond]

Is this really fixed by #1070 ?
I think the cause of the error (here at least) is that msgpack was upgraded to 1.0.0 before deoplete.

If anyone else comes here, just run :call dein#update()

[Shougo]

Is this really fixed by #1070 ?

Yes. I think you have not updated deoplete.

[MWers]

Echoing @Shougo's question, I received the TypeError: __init__() got an unexpected keyword argument 'encoding' error when running an old version of deoplete (sha https://github.com/Shougo/deoplete.nvim/commit/bb2b163) with msgpack 1.0.0. If anyone finds this thread by searching for the error message above and initially thinks "but I'm running the correct version of msgpack", make sure your deoplete is recent. 😄

[OJFord]

@Shougo The latest tag (5.2) is before this fix, have you intended to stop tagging releases, or just not done yet? Cheers.

[Shougo]

OK. I have released 6.0 version.

[OJFord]

Many thanks!
