R language server failed to start after installation on Windows

[hongyuanjia]

I am trying to move my config from nvim-lsp-installer to mason.nvim and mason-lspconfig.nvim. Basically, I did not change lsp config. The r-language-server was successfully installed.

[INFO  2022/9/13 14:03:12] ...acker\start\mason.nvim/lua\mason-core\installer\init.lua:142: Installation succeeded for Package(name=r-languageserver)

Output of :Mason

Output of :LspInfo

I have confirmed that the R packages and the .cmd file have been downloaded/created at C:\Users\hongy\AppData\Local\nvim-data\mason\packages\r-languageserver\.

The r-languageserver.cmd can be manually executed via:

C:\Users\hongy\AppData\Local\nvim-data\mason\packages\r-languageserver>r-languageserver.cmd
<environment: namespace:languageserver>
[2022-09-13 14:54:51.741] Error: stdin connection close

2: self$read_line()
3: self$read_header()
4: self$fetch(blocking = FALSE)
[2022-09-13 14:54:51.747] exiting

But after I ran :LspStart, it errored

Spawning language server with cmd: `r-languageserver` failed. The language server is either not installed, missing from PATH, or not executable.

My lsp config

    use "neovim/nvim-lspconfig"
    use {
        "williamboman/mason.nvim",
        after = "nvim-lspconfig",
        config = function()
            require("mason").setup()
        end
    }
    use {
        "williamboman/mason-lspconfig.nvim",
        after = "mason.nvim",
        requires = {
            "folke/lua-dev.nvim",
            "simrat39/rust-tools.nvim",
            "jose-elias-alvarez/null-ls.nvim"
        },
        config = function()
            require("mason-lspconfig").setup({
                ensure_installed = { "sumneko_lua" }
            })

            require("null-ls").setup({
                sources = {
                    require("null-ls").builtins.completion.spell
                }
            })

            local on_attach = function(client, bufnr)
                ......
            end

            local lspconfig = require("lspconfig")

            require("mason-lspconfig").setup_handlers({
                function(server_name)
                    require("lspconfig")[server_name].setup({ on_attach = on_attach })
                end,
                ......
            })
        end
    }

Hello! This should be fixed in williamboman/mason-lspconfig.nvim#56. Try pulling latest plugin versions
