Unkown function: SemshiBufWipeout when closing windows

[AucaCoyan]

Sorry, I ran :UpdateRemotePlugins and I received this, is this ok?

function remote#host#UpdateRemotePlugins[6]..<SNR>92_RegistrationCommands[15]..remote#host#Require[10]..provider#pythonx#Require[13]..provider#Poll, line 4

Failed to load python3 host. You can try to see what happened by starting nvim with
$NVIM_PYTHON_LOG_FILE set and opening the generated log file. Also, the host stderr
is available in messages.

In Neovim you need to run :UpdateRemotePlugins to update the plugin manifest and register remote plugin commands and functions. Could you check if you did that?

If you see such errors

Failed to load python3 host. You can try to see what happened by starting nvim with

You need to configure g:python3_host_prog properly in your init.vim config and install pynvim there:

python3 -m pip install --upgrade --force-reinstall pynvim

and make sure python3 host works OK:

:echo py3eval("sys.version_info")

and then :UpdateRemotePlugins again.

After using :UpdateRemotePlugins, it seems that the issue is gone. This is a little weird because I have set up the post-update hooks for this plugin. The :UpdateRemotePlugins command should be run automatically on each installation or update.

FYI, my vim-plug statement for semshi:

Plug 'numirias/semshi', { 'do': ':UpdateRemotePlugins', 'for': 'python' }

[jdhao]

Maybe it is because I have added the 'for': 'python' part so that the :UpdateRemotePlugins command will not be run automatically?

[numirias]

@jdhao TBH, I never got automatic UpdateRemotePlugins to work myself. I don't think it's due to something within this plugin, though.

[jdhao]

I also use deoplete and set up the post-update hook, and it works great:

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

Maybe I should file an issue in vim-plug repo. Thanks for your answer!

[jdhao]

It seems that for option should not be used. Otherwise, command provided by semshi seems not to be loaded. Ref: junegunn/vim-plug#593 (comment)

[numirias]

Weird, in my config I'm not using for:.

[jdhao]

My minimal working init.vim is as follows:

if has('win32')
    let s:PLUGIN_HOME=expand('~/AppData/Local/nvim/plugged')
else
    let s:PLUGIN_HOME=expand('~/.local/share/nvim/plugged')
endif

call plug#begin(s:PLUGIN_HOME)
Plug 'numirias/semshi', { 'do': ':UpdateRemotePlugins' }
call plug#end()

[numirias]

Thanks, not sure why it doesn't work for me. Closing the issue now since it doesn't seem related to Semshi

[intramuros]

Hi, I have the same issue and this error:

E117: Unknown function: SemshiBufWipeout

appears even after deleting semshi plugin.

[numirias]

@intramuros You need to run :UpdateRemotePlugins.

Thank you @wookayin !
