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?

[Eytan425]

Can you send the link to setup the neovim please

I just noticed that as long as Mason is not loaded the MasonInstallAll cmd is there.

as soon as Mason gets loaded it disappears ... at least on one of my machines .. not sure what's going on here but maybe it helps someone who stumbles upon this thread in the future.

the command MasonInstallAll is ONLY available in NvChad
