This is a very lightweight companion plugin for nvim-lspconfig. It adds the missing :LspInstall <language> command to conveniently install language servers.

The language servers are installed locally into stdpath("data"), you can use :echo stdpath("data") to find out which directory that is on your machine.

Isn't this something I should use my system's package manager for?


Via Vim-Plug

Plug 'neovim/nvim-lspconfig'
Plug 'kabouzeid/nvim-lspinstall'

The following is a good starting point to integrate with nvim-lspconfig.

require'lspinstall'.setup() -- important

local servers = require'lspinstall'.installed_servers()
for _, server in pairs(servers) do

For a complete example you might refer to my personal configuration in the Wiki.


  • :LspInstall <language> to install/update the language server for <language> (e.g. :LspInstall python).
  • :LspUninstall <language> to uninstall the language server for <language>.
  • require'lspinstall'.setup() to make configs of installed servers available for require'lspconfig'.<server>.setup{}.

A configuration like this automatically reloads the installed servers after installing a language server via :LspInstall such that we don't have to restart neovim.

local function setup_servers()
  local servers = require'lspinstall'.installed_servers()
  for _, server in pairs(servers) do


-- Automatically reload after `:LspInstall <server>` so we don't have to restart neovim
require'lspinstall'.post_install_hook = function ()
  setup_servers() -- reload installed servers
  vim.cmd("bufdo e") -- this triggers the FileType autocmd that starts the server

Custom Installer

Use require'lspinstall/servers'.<lang> = config to register a config with an installer. Here config is a LSP config for nvim-lspconfig, the only difference is that there are two additional keys install_script and uninstall_script which contain shell scripts to install/uninstall the language server.

The following example provides an installer for bash-language-server.

-- 1. get the default config from nvim-lspconfig
local config = require"lspinstall/util".extract_config("bashls")
-- 2. update the cmd. relative paths are allowed, lspinstall automatically adjusts the cmd and cmd_cwd for us!
config.default_config.cmd[1] = "./node_modules/.bin/bash-language-server"

-- 3. extend the config with an install_script and (optionally) uninstall_script
require'lspinstall/servers'.bash = vim.tbl_extend('error', config, {
  -- lspinstall will automatically create/delete the install directory for every server
  install_script = [[
  ! test -f package.json && npm init -y --scope=lspinstall || true
  npm install bash-language-server@latest
  uninstall_script = nil -- can be omitted

Make sure to do this before you call require'lspinstall'.setup().

Note: don't replace the / with a . in the require calls above (see here if you're interested why).


  • require'lspinstall'.setup()

  • require'lspinstall'.installed_servers()

  • require'lspinstall'.install_server(<lang>)

  • require'lspinstall'.post_install_hook

  • require'lspinstall'.uninstall_server(<lang>)

  • require'lspinstall'.post_uninstall_hook

  • require'lspinstall/servers'

  • require'lspinstall/util'.extract_config(<lspconfig-name>)
