the LSP server could not download from GitHub

[Reverier-Xu]

Version: 0e3585b

When open a file, it will produce logs:

/usr/share/nvim/runtime/lua/vim/lsp/rpc.lua:800: Spawning language server with cmd: `{ ".local/share/nvim/lazy/copilot.lua/copilot/linux-x64/copilot-language-server-1.292.0", "--stdio" }` failed. The language server is either not installed, missing from PATH, or not executable.

2025-03-27 09:54:01.602 [40] [ERROR]: LSP client failed to start (no client ID returned)
[loops]
...

I found the .local/share/nvim/lazy/copilot.lua/copilot/linux-x64/copilot-language-server-1.292.0.zip is just a txt file with one line:

Cookies must be enabled to use GitHub.

seems a download error?

[AntoineGS]

Yes the curl command to download the zip file seems to fail for some reason. I just pushed an attempt at resolving the issue, but I am really not sure if it will work so let me know if it does or not.

[Reverier-Xu]

0da7ebc11bf63fe0591f664430266dfc87d77dbf fails with the same reason, still not working

[Reverier-Xu]

the original curl command seems ok

[AntoineGS]

Very odd, until we figure it out you can just extract the zip file in that same folder and the plugin will pick it up.

Hey, I thought i was having the same issue since i also had the notification saying: [ERROR]: LSP client failed to start (no client ID returned)

But in the flood of notifications i found this one:

Stating that it could not create the linux-x64 folder. I simply did an mkdir in ~/.local/share/nvim/copilot.lua/copilot/linux-x64

Restarted neovim and everything went well this time:

So maybe the issue is more related to directory creation?

[Reverier-Xu]

@NicolasGB maybe another bug? I have this directory though.

[rosshadden]

I had this problem and manually creating the linux-x64 directory worked for me too.

[AntoineGS]

I have an idea to resolve the directory issue, but the one reported in this Issue initially is not the same from what I can see.

[Julian]

In my case the directory existed and the .zip file existed but nothing unzipped it, even if I removed it and tried having copilot.lua (presumably?) download it again.

This essentially hung my nvim as above -- but what fixed it here was basically just doing this myself for now, so unzip copilot-language-server-darwin-arm64-1.292.0.zip followed by mv copilot-language-server copilot-language-server-1.292.0 which seems to be the executable name expected.

This worked for me as well. Downloaded the zip from https://github.com/github/copilot-language-server-release/releases/download/1.292.0/copilot-language-server-linux-x64-1.292.0.zip

[AntoineGS]

For anyone having an issue with the file manipulation, could you pull the new version (just added a log), add this to your configuration:

    require("copilot").setup {
      ...
      logger = {
        file_log_level = vim.log.levels.TRACE,
      },
      ...

Then replicate the issue and post the copilot_lua.log file generated? On linux it should be in ~/.local/state/nvim/copilot-lua.log

[saljic-heijmans]

Issue also occurs on LazyVim on windows, downloading the exe renaming it and placing it in the directory fixes the issue, but that's a workaround

[AntoineGS]

Do you have logs? :) They are in ~\AppaData\Local\ on Windows

[saljic-heijmans]

When i fresh install it i get this using lazyvim package manager

'...nvim-data/lazy/lazy.nvim/lua/lazy/manage/task/plugin.lua:26: Vim:2025-03-27 16:52:59.664 [1] [ERROR]: error starting LSP client: ...les/Neovim/share/nvim/runtime/lua/vim/lsp/_transport.lua:68: Spawning language server with cmd: { "C:/Users/seal1/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/copilot-language-server-1.292.0.exe", "--stdio" } failed. The language server is either not installed, missing from PATH, or not executable.'

i can not find any file named copilot-lua.log in my appdata unfortunately

[AntoineGS]

Did you add the configuration described here?: https://github.com/zbirenbaum/copilot.lua/issues/408#issuecomment-2758411881

[saljic-heijmans]

I did, but i'm also using the environment variable for windows which makes the config directory change to ~/.config instead of AppData I'm not sure whether that also influences the log files directory, because the nvim-data directory is still in AppData

[AntoineGS]

What shell are you using on Windows? I am starting to think it may have something to do with this

[saljic-heijmans]

I've tried with Powershell and Nushell, the folder 'nvim-data/lazy/copilot.lua/copilot' which should contain the 'win32-x64' folder and the binary only contains a '.gitignore' and 'package.json' file, I saw in the repo that you use curl to download the binary, so I tried installing that on windows to see if it will make a difference but it did not still no .exe

[AntoineGS]

I just pushed another change to use the built-in vim.fn.mkdir which should be better at handling varieties in shells and OSes.

I use Nushell on Windows and it is working OK. Let's manually enter the commands and see which one fails in this case. You will need to replace ~ with your user path as curl does not seem to like ~ to download the zip file:

curl -v -s -L -c "~/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/cookies.txt" -b "~/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/cookies.txt" -o "~/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/copilot-language-server-win32-x64-1.292.0.zip" "https://github.com/github/copilot-language-server-release/releases/download/1.292.0/copilot-language-server-win32-x64-1.292.0.zip"

And finally unzip it:

powershell -Command "Expand-Archive -Path ~/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/copilot-language-server-win32-x64-1.292.0.zip -DestinationPath ~/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64"

[saljic-heijmans]

After your change the win32-x64 folder get created successfully, the curl command works fine if I use full path, but doesn't work if i use - and the powershell extract command works fine, but the extracted file does not, it is called copilot-language-server.exe and the plugin expects copilot-language-server-1.292.0.exe, otherwise it doesn't start up

[AntoineGS]

If the folder is created automatically, what is the error in NeoVim? Since the commands work I would expect it to download fine through NeoVim.

[saljic-heijmans]

when i delete the nvim data of copilot-lua, it reinstalls it I briefly see on the bottom downloading but very quickly after that I get the error

'...nvim-data/lazy/lazy.nvim/lua/lazy/manage/task/plugin.lua:26: Vim:2025-03-27 16:52:59.664 [1] [ERROR]: error starting LSP client: ...les/Neovim/share/nvim/runtime/lua/vim/lsp/_transport.lua:68: Spawning language server with cmd: { "C:/Users/seal1/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/copilot-language-server-1.292.0.exe", "--stdio" } failed. The language server is either not installed, missing from PATH, or not executable.'

so I have no clue, what happened with the downloading, is there somewhere I can find the logs for that part?

[saljic-heijmans]

Okay I managed to get the logs

2025-03-27 18:09:22.514 [10] [ERROR]: Error downloading file: Error: [31mnu::shell::file_not_found[0m

[AntoineGS]

Can you post what comes before? It should log the command it is about to run if you set your config to trace.

[saljic-heijmans]

[AntoineGS]

hmm that looks normal to me, if you add -v after curl and run that command, does it work?

[saljic-heijmans]

I'm going to drive now for an hour, so I won't be able to give you quick feedback, but when I get home I will continue monitoring this conversation.

[saljic-heijmans]

-v did not make any difference quickly tried it out!

[AntoineGS]

-v only means verbose so it should output a log, so if you run the follow you should be able to get a log which you can post back here:

curl -v -s -L -c "C:/Users/seal1/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/cookies.txt" -b "C:/Users/seal1/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/cookies.txt" -o "C:/Users/seal1/AppData/Local/nvim-data/lazy/copilot.lua/copilot/win32-x64/copilot-language-server-win32-x64-1.292.0.zip" "https://github.com/github/copilot-language-server-release/releases/download/1.292.0/copilot-language-server-win32-x64-1.292.0.zip"

Just hit this myself.

For those trying to get over this error and continue working, and using lazy.nvim, you can pin it to a previous / unbroken commit, e.g.:

  { "zbirenbaum/copilot.lua", commit = "99654fe9ad6cb2500c66b178a03326f75c95f176" },
