Neovim中无法为.sol文件挂载solidity-lsp的问题求助

Hey there, let’s work through your solidity-lsp problems step by step—since you’re new to Neovim and Lua, I’ll keep each step straightforward and explain what’s going on behind the scenes.

1. Fix the Inconsistent Executable Status #

You mentioned Mason installed solidity-ls but it wouldn’t run in the terminal, then you installed it globally via npm. First, we need to make sure Neovim is pointing to the correct working executable:

• Run which solidity-ls in your terminal to get the full path (e.g., /usr/local/bin/solidity-ls)
• In your LSP config for solidity, explicitly set the cmd option to this path to avoid confusion between Mason’s local install and your global npm install:

require('lspconfig').solidity.setup({
  cmd = { '/usr/local/bin/solidity-ls' }, -- Replace with your actual path from `which`
  -- We’ll add more config here next
})

2. Fix Root Directory Detection & the ipairs Error #

Your manual root_dir returning the current working directory is likely causing issues—solidity-lsp expects a proper project root (marked by files like hardhat.config.js, truffle-config.js, or a .git folder). The SERVER_REQUEST_HANDLER_ERROR with ipairs usually pops up when the LSP receives invalid data from a misconfigured root_dir.

Update your config to use a smarter root detector that prioritizes actual Solidity project markers, with a fallback to the current directory:

require('lspconfig').solidity.setup({
  cmd = { '/usr/local/bin/solidity-ls' },
  on_attach = function(client, bufnr)
    -- Keep your existing on_attach logic here (if any)
    -- Example basic mappings to get you started:
    vim.keymap.set('n', 'K', vim.lsp.buf.hover, { buffer = bufnr })
    vim.keymap.set('n', 'gd', vim.lsp.buf.definition, { buffer = bufnr })
  end,
  root_dir = function(fname)
    -- Look for standard Solidity project markers first
    local project_root = require('lspconfig.util').root_pattern(
      'hardhat.config.js',
      'hardhat.config.ts',
      'truffle-config.js',
      'foundry.toml',
      '.git'
    )(fname)
    -- Fallback to current working directory if no project markers are found
    return project_root or vim.fn.getcwd()
  end,
})

3. Address Neovim Version Compatibility #

You’re using NVIM v0.7.2, which is a bit outdated. The LSP client in older Neovim versions has known bugs with modern language servers like solidity-ls. If the above steps don’t resolve the issue, consider upgrading to a newer stable version (v0.9+):

sudo add-apt-repository ppa:neovim-ppa/stable
sudo apt update
sudo apt upgrade neovim

This will fix many underlying compatibility issues.

Final Checks #

After updating your config and (optionally) upgrading Neovim:

1. Run :luafile % to reload your config
2. Open a .sol file in a valid Solidity project directory (or any directory for testing)
3. Run :LspInfo to verify:
   • The solidity server shows as "attached"
   • The cmd path matches what you set
   • The root_dir points to your project root (or current directory)

If you still hit issues, double-check that your global solidity-ls works by running solidity-ls --version in the terminal—if it throws an error, reinstall it with npm uninstall -g solidity-ls && npm install -g solidity-ls.
