Can't get lua-language-server executable

[trevarj]

I'm having this error when I use the following config:

Error, cmd ["$HOME/.local/share/nvim/lspinstall/lua-language-server/bin/Linux/lua-language-server"] is not executable.

Config:

-- set the path to the sumneko installation; if you previously installed via the now deprecated :LspInstall, use
local sumneko_root_path = "$HOME/.local/share/nvim/lspinstall/lua-language-server"
local sumneko_binary = sumneko_root_path.."/bin/Linux/lua-language-server"

require'lspconfig'.sumneko_lua.setup {
  cmd = {sumneko_binary, "-E", sumneko_root_path .. "/main.lua"};
  settings = {
    Lua = {
      runtime = {
        -- Tell the language server which version of Lua you're using (most likely LuaJIT in the case of Neovim)
        version = 'LuaJIT',
        -- Setup your lua path
        path = vim.split(package.path, ';'),
      },
      diagnostics = {
        -- Get the language server to recognize the `vim` global
        globals = {'vim'},
      },
      workspace = {
        -- Make the server aware of Neovim runtime files
        library = {
          [vim.fn.expand('$VIMRUNTIME/lua')] = true,
          [vim.fn.expand('$VIMRUNTIME/lua/vim/lsp')] = true,
        },
      },
    },
  },
}

User error, sorry.

How did you fix it?

[trevarj]

@vuki656 make the lua-language-server executable with chmod +x lua-language-server

Looking at this again, I wouldn't call it user error @trevarj (though I appreciate you finding a solution) this is probably something this extension should do... especially since the instructions don't tell people they need to make it executable. Thanks for bringing it up (again)!

For anyone else this may help I had installed the lua lsp using :LspInstall command this expects your lua language server to be placed at a specific location. Make sure once you have compiled it you have it in the correct place.

I saw this error today while setting up sumenko_lua lsp. I moved the executable to a different folder and forgot to update the path info in the lsp-config.lua file.

My fault, but the error was not informative in this case. It should have told me that the exe lua-language-server cannot be found.

@m42martin good to know! I will try to get to that when I have a free moment.
