Installation method

Use lazy.nvim:

{
  "yetone/avante.nvim",
  event = "VeryLazy",
  lazy = false,
  version = false, -- set this if you want to always pull the latest change
  opts = {
     provider = "gemini",

      gemini = {
        model = "gemini-2.0-flash",
        temperature = 0,
        max_tokens = 4096,
      },

      behaviour = {
        auto_suggestions = false, -- Experimental stage
        auto_set_highlight_group = true,
        auto_set_keymaps = true,
        auto_apply_diff_after_generation = false,
        support_paste_from_clipboard = false,
      },
  },
  -- if you want to build from source then do `make BUILD_FROM_SOURCE=true`
  build = "make",
  -- build = "powershell -ExecutionPolicy Bypass -File Build.ps1 -BuildFromSource false" -- for windows
  dependencies = {
    "nvim-treesitter/nvim-treesitter",

I have the same issue, with the same provider.
