Ambiguous use of user-defined command' error on specifically windows

[umutondersu]

Describe the bug

I get the error I mention at the end of the description when I use any of the commands given the Readme. I believe it is only a windows error as in my Ubuntu WSL I have not received this error.

Error executing Lua callback: vim/_editor.lua:341: nvim_exec2(): Vim:E464: Ambiguous use of user-defined command: CopilotChat Explain how it works.
stack traceback:
[C]: in function 'nvim_exec2'

Reproduction

Use the config given in the usage section on Windows. Try any command or keybindings.

When I run :verb command Copilot, there is an extra command on linux, the top one on the screenshot

I think the problem stems from this. In windows this command is not correctly created.

[Espacio-root]

I momentarily faced the same issue on arch linux upon installation. It weirdly disappeared after a while. Still don't know what caused and fixed the issue.

[jellydn]

Could you run :healthcheck command and share the output here? Thanks.

@jellydn @umutondersu
I had the same error on macOS (using packer instead of lazy). However, when I ran verb command Copilot, I had no CopilotChat command listed. So, this may be a different issue.
Here's what I did to resolve the issue, it may work for your issue as well.

First, :healthcheck showed I was missing pynvim.
I installed that with pip, and :healthcheck no longer returned any error, but the Vim:E464 error was still happening.

I then ran :UpdateRemotePlugins and got errors telling me some modules were missing: python-dotenv, chardet, and prompt-toolkit. (Obviously, I had to run it multiple times until all dependencies were met; each run only revealed one missing dependency)
Installing these with pip, running :UpdateRemotePlugins (and getting no errors), and then reopening neovim resolved this for me.

[James-Darko]

I was running into the same issue. I realized I forgot to run :UpdateRemotePlugins before restarting. So it's working for me now.

[umutondersu]

Could you run :healthcheck command and share the output here? Thanks.

This is the output

CopilotChat: require("CopilotChat.health").check()

CopilotChat.nvim health check ~
- OK Python version 3.9 is supported
- WARNING pynvim version Traceback (most recent call last):
  File "C:\Users\umuts\AppData\Local\Temp\selc.0.py", line 1, in <module>
  import pynvim; print(pynvim.__version__)
  ModuleNotFoundError: No module named 'pynvim' is not supported

Which is weird because I already have pynvim installed anu used UpdateRemotePlugins. I'm investigating the reason.

[jellydn]

Thanks @umutondersu I think you got the same issue with @nolanking90 You should install pynvim on your PC. You should find this command on readme. Could you please try again?

pip install python-dotenv requests pynvim==0.5.0 prompt-toolkit

[umutondersu]

Thanks for the fast reply. I have run this command before my installation, so I do not think this is the issue. I have tried to run it again with the force flag but the result is still the same. For reference this is my pip show pynvim output.

I have the same issue, I have python installed, neovim finds my python installation, I have pynvim installed as well.

I get a: Warning Python 3 is required from the checkHealth of this plugin but later on it says python works fine.

[jellydn]

Hi all,

There are two new commands from @ziontee113 on canary Could you take a try and let us know if any issue?

[umutondersu]

I have tried the canary branch but the problem still persists.

[Krujo]

Same for me

[jellydn]

FYI - There is a similar issue which was closed by the user due to his config. #38

Make sure that you do the following after installing the plugin.

3. Open up Neovim and run :UpdateRemotePlugins
4. Restart Neovim

[Krujo]

Should the plugin work with https://github.com/junegunn/vim-plug?

[jellydn]

Should the plugin work with https://github.com/junegunn/vim-plug?

I am not sure as I didn't use Plug but I guess it should work. You might refer to this commit to get the idea with Plug jellydn/lazy-nvim-ide@5128bc3

[jinzhongjia]

oh, this issue is not solved

It still happens on windows. I tried to write a python file for testing. It seems that: the UpdateRemotePlugins command cannot recognize the python plug-in under windows, and the python plug-in registration result is empty.

[rossjaywill]

I'm seeing this issue on linux too, I have all of the pip dependencies installed and the :UpdateRemotePlugins command returns:

remote/host: python3 host registered plugins ['copilot-plugin.py']
remote/host: generated rplugin manifest: 1

:checkhealth CopilotChat
Does not show any errors/warnings either.

I've tried this with both copilot.lua and copilot.vim.

(edit: and tried both main and canary branches, as well as reverting to a previous commit from early January)

Do you restart Neovim after run the update remote plug-in command?

[rossjaywill]

@jellydn yes, multiple times - no luck.

[jellydn]

Could you share with me the output from :healtcheck command? @rossjaywill

[rossjaywill]

Thanks for taking a look!

[jinzhongjia]

It's strange. I use UpdateRemotePlugins under both wsl and windows. wsl can be registered normally, but windows is empty.
the result for windows:

Even the python script I wrote based on the neovim documentation doesn't work. I'm trying to find out why.

[jellydn]

Hi all,

I've marked this as won't fix as I can't reproduce this on Windows. I am a Mac user and it's tricky for me to investigate the issue.

cc @gptlang How about you?

[gptlang]

I'm a Linux user. Don't have Windows available to test.

[rossjaywill]

I'm seeing this issue on linux too (red hat 9), though - so I don't believe this is windows specific.

What version of python are you all running the backend with?

❯ python -V
Python 3.8.8

[jellydn]

Just FYI

CopilotChat: require("CopilotChat.health").check()

CopilotChat.nvim health check ~
- OK Python version 3.11 is supported
- OK pynvim version 0.5.0 is supported

[jinzhongjia]

I don’t know if it can be modified to a plugin like leaderf that does not require rplugin.

[jinzhongjia]

python : 3.12.1 (I have also tested on 3.10, nothing changes)
pynvim: 0.5.0

[jellydn]

A user faced a similar issue; here is how he fixed it. #43 (comment) I think this is a common issue so I've added to readme the usage, installation, etc but might be not enough. Any suggestions?

Has no effect on windows

[rossjaywill]

No effect on my linux instance either

[jellydn]

Wow, how about this? #45 (comment)

[waynebowie99]

I'm also running into this. I had a couple things run with my install

1. I had Python 3.9 installed through choco and Python 3.11 installed through another means
   • Neovim was only recognizing 3.9 and was thinking pynvim was not installed
2. Python 3.11 did not include a python3.exe which the plugin was expecting
   • I fixed this by creating a sym link using New-Item -Path 'C:\Program Files\Python311\python3.exe' -ItemType SymbolicLink -Value 'C:\Program Files\Python311\python.exe'

With these changes, my checkhealth is all green (exactly the same as #25 (comment)) but I am still getting an ambiguous error.

I'm willing to provide help in any way I can

[gptlang]

btw from the initial error message: E464

https://superuser.com/questions/1322471/vim-e464-ambiguous-use-of-user-defined-command

Are there multiple commands being registered for the same thing?

[waynebowie99]

For me, CopilotChat is not registered at all. Here is everything in my command list related to copilot

!   Copilot           ?            <Lua function> <Lua 130: ~/AppData/Local/nvim-data/lazy/copilot.lua/plugin/copilot.lua:8>

[gptlang]

@waynebowie99 Looks like the Python script didn't get loaded.

This is what mine looks like:

    CopilotChat       1                        call remote#define#CommandBootstrap("python3", "/var/home/acheong/.local/sha 
    CopilotChatAutocmd *                       call remote#define#CommandBootstrap("python3", "/var/home/acheong/.local/sha 
    CopilotChatExplain *   .                   <Lua 7: ~/.local/share/nvim/lazy/CopilotChat.nvim/lua/CopilotChat/init.lua:33

Did you :UpdateRemotePlugins? Check ~/.local/share/nvim/rplugin.vim

It should look something like this:

" python3 plugins
call remote#host#RegisterPlugin('python3', '~/.local/share/nvim/lazy/CopilotChat.nvim/rplugin/python3/copilot-agent.py', [
      \ {'sync': v:false, 'name': 'CopilotChatVsplit', 'type': 'command', 'opts': {'nargs': '1'}},
      \ {'sync': v:false, 'name': 'CopilotChatVsplitVisual', 'type': 'command', 'opts': {'nargs': '1', 'range': ''}},
      \ {'sync': v:false, 'name': 'CopilotChatInPlace', 'type': 'command', 'opts': {'nargs': '*', 'range': ''}},

     \ ])

     \ ])

I have been trying to get this working on osx for the past 2 hours, tried everything :UpdateRemotePlugins, :checkhealth, ~/.local/share/nvim/rplugin.vim, all good

restarted neovim / OS multiple times

but still getting "Ambiguous use of user-defined command error"

[edward-s]

ok I think I have the same issue with @waynebowie99 of CopilotChat not registered in command

this is my ~/.local/share/nvim/rplugin.vim

" python3 plugins
call remote#host#RegisterPlugin('python3', '/Users/edward/.local/share/nvim/lazy/CopilotChat.nvim/rplugin/python3/copilot-agent.py', [
      \ {'sync': v:false, 'name': 'CopilotChatVsplit', 'type': 'command', 'opts': {'nargs': '1'}},
      \ {'sync': v:false, 'name': 'CopilotChatVsplitVisual', 'type': 'command', 'opts': {'nargs': '1', 'range': ''}},
      \ {'sync': v:false, 'name': 'CopilotChatInPlace', 'type': 'command', 'opts': {'nargs': '*', 'range': ''}},
      \ {'sync': v:false, 'name': 'CopilotChatAutocmd', 'type': 'command', 'opts': {'nargs': '*'}},
      \ {'sync': v:false, 'name': 'CopilotChatMapping', 'type': 'command', 'opts': {'nargs': '*'}},
     \ ])
call remote#host#RegisterPlugin('python3', '/Users/edward/.local/share/nvim/lazy/CopilotChat.nvim/rplugin/python3/copilot-plugin.py', [
      \ {'sync': v:false, 'name': 'CopilotChat', 'type': 'command', 'opts': {'nargs': '1'}},
     \ ])

Update: still no go, I guess I'll stop for now and try again in the future, still, thanks for the plugin

[edward-s]

omg it's working now, turns out my rplugin is disabled in lazy config
apparently, it is also disabled in a few neovim distros, i.e: nvchad https://github.com/NvChad/NvChad/blob/8214d4e8589aa6625c6db077b8eb199e7ebc1929/lua/plugins/configs/lazy_nvim.lua#L37

hope this helps someone else!

That's why I pinned 2 other issues. NVChad maintainer also left comment there. #38 (comment)

[edward-s]

i completely missed out that other pinned thread, thanks anyways! great plugin!
