MasonInstallAll is missing

[adorostkar]

Hello all,
I have installed Mason through Lazy.nvim but when I try to use the command MasonInstallAll it is not there. Is there something I am missing?

here is my Lazy setup. Please tell me if something is wrong with this as I am fairly new with neovim

    {
        "williamboman/mason.nvim",
        opts = {
            ensure_installed = {
                "clangd",
                "lua-lsp",
                "bash-language-server",
                "clang-format",
            }
        },
        config = function()
            require('mason').setup()
        end,
    },
    {
        "williamboman/mason-lspconfig.nvim",
        dependencies = {
            "williamboman/mason.nvim",
        },
        config = function()
            require("mason").setup()
            require("mason-lspconfig").setup()

            require("mason-lspconfig").setup_handlers {
                -- The first entry (without a key) will be the default handler
                -- and will be called for each installed server that doesn't have
                -- a dedicated handler.
                function (server_name) -- default handler (optional)
                    require("lspconfig")[server_name].setup {}
                end,
                -- Next, you can provide a dedicated handler for specific servers.
                -- For example, a handler override for the `rust_analyzer`:
                -- ["rust_analyzer"] = function ()
                --     require("rust-tools").setup {}
                -- end
            }
        end,
    },

There doesn't seem to be any such command. https://github.com/williamboman/mason.nvim?tab=readme-ov-file#commands

I've double-checked that Mason is installed in my Neovim environment, and I've also tried restarting Neovim after making changes to plugins.lua and running :MasonInstallAll again. Unfortunately, clangd and clang-format are still not getting installed.

Did you find any solutions ?

It would only make sense to have it, since it would allow for headless nvim installs nvim --headless +MasonInstallAll +qall that would automatically read from the ensure_installed value

EDIT :

Looking at :

• mason.nvim/blob/main/lua/mason/api/command.lua )
• mason-lspconfig.nvim/blob/main/lua/mason-lspconfig/ensure_installed.lua
  We can write something like

-- MasonInstallAll command implementation
vim.api.nvim_create_user_command("MasonInstallAll", function()
    local lspconfig_to_package = require("mason-lspconfig.mappings.server").lspconfig_to_package
    local packages = {
        'bashls', 'cssls', 'graphql', 'lua_ls', 'rust_analyzer', 'somesass_ls',
        'stylelint_lsp', 'shellcheck', 'tsserver', 'yamlls',
    }

    local package_args = {}
    
    for _, package in ipairs(packages) do
        local server_name = lspconfig_to_package[package]
        if server_name then
            table.insert(package_args, server_name)
        else
            table.insert(package_args, package)
        end
    end                                                        

It does work headlessly. nvim --headless "+MasonInstallAll" +qall
You will probably want to modify this if youre installing only lsps, or only regular packages

@advl This gives me Not an editor command: MasonInstallAll

[ryanpeach]

Also, several plugins in a config can add things to ensure_installed when their "config" function is run, how can we be sure they have all added their stuff if they are lazy loaded?

The same problem here:

⬢ [Docker] ❯ nvim --headless "+MasonInstallAll" +qall
Error detected while processing command line:
E492: Not an editor command: MasonInstallAll

Have you managed to find a root cause of it?

Can you send the link to setup the neovim please
