Hi @k-martynov, based on your log, it's the old version. We only have python3/copilot-agent.py on main branch. Could you share your config? You also find my config on readme. Thanks.

[k-martynov]

@jellydn here is my config:

  {
    "jellydn/CopilotChat.nvim",
    dependencies = { "zbirenbaum/copilot.lua" },
    opts = {
      mode = "split",
      debug = false,
      prompts = {
        Explain = "Explain how it works.",
        Review = "Review the following code and provide concise suggestions.",
        Tests = "Briefly explain how the selected code works, then generate unit tests.",
        Refactor = "Refactor the code to improve clarity and readability.",
        Spelling = "Please correct any grammar and spelling errors in the following text.",
        Wording = "Please improve the grammar and wording of the following text.",
      },
    },
    build = function()
      vim.defer_fn(function()
        vim.cmd("UpdateRemotePlugins")
        vim.notify("CopilotChat - Updated remote plugins. Please restart Neovim.")
      end, 3000)
    end,
    event = "VeryLazy",
    keys = {
      { "<leader>cce", "<cmd>CopilotChatExplain<CR>",  desc = "CopilotChat - Explain code" },
      { "<leader>cct", "<cmd>CopilotChatTests<CR>",    desc = "CopilotChat - Generate tests" },
      { "<leader>ccr", "<cmd>CopilotChatReview<CR>",   desc = "CopilotChat - Review code" },
      { "<leader>ccR", "<cmd>CopilotChatRefactor<CR>", desc = "CopilotChat - Refactor code" },
      { "<leader>ccS", "<cmd>CopilotChatSpelling<CR>", desc = "CopilotChat - Correct spelling" },
      { "<leader>ccw", "<cmd>CopilotChatWording<CR>",  desc = "CopilotChat - Improve wording" },
    },
  },

After I've moved to canary(I've added to config branch = "canary") version I'm started getting this error:

Hello, there will be a tons of typing errors when using Python 3.10 (i try tweek the repo by my self). A more convenient solution is to install Python 3.12 using pyenv and set it as the global version, without compromising the pre-installed Python if you're using Ubuntu.

@carlesoctav @jellydn thanks!

after updating to python 3.12 with pyenv and running again this line: pip install python-dotenv requests pynvim==0.5.0 prompt-toolkit

updateremoreplugins went well
