Error on startup

[bitterjug]

When I install I get the following on startup:

Error detected while processing VimEnter Auto commands for "*":
E117: Unknown function: NeotagsInit
Press ENTER or type command to continue

And this when I try and run :NeotagsToggle

E117: Unknown function: NeotagsToggle

Did you run :UpdateRemotePlugins ?

[trentjones21]

@c0r73x Had the same error. Running :UpdateRemotePlugins fixed it for me

[bitterjug]

I didn't even know :UpdateRemotePlugins was a thing!! Tried it today:

function remote#host#UpdateRemotePlugins[6]..<SNR>152_RegistrationCommands[15]..remote#host#Require[10]..provider#pythonx#Require, line 15
Vim(if):E475: Invalid argument: Channel id must be a positive integer
function remote#host#UpdateRemotePlugins[6]..<SNR>152_RegistrationCommands[15]..remote#host#Require[10]..provider#pythonx#Require, line 27
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.
remote/host: generated rplugin manifest: /home/skipperm/.local/share/nvim/rplugin.vim

Tried

NVIM_PYTHON_LOG_FILE=/tmp/log nvim

but /tmp/log doesn't exist.

Uh, wait! This is my work machine and itsays 0 to :echo has("python3"). :(

Humm it's strange that pip3 says that you have the neovim package. Not sure how I can help you other than this https://github.com/neovim/neovim/wiki/Installing-Neovim where they explain how to get python2/3 support in neovim.
