Actual behavior

nvim-lsp-installer seems to try to install the server which not configured.

the configuration of nvim-lsp-installer:

use {
    'williamboman/nvim-lsp-installer',
    config = function()
        require('nvim-lsp-installer').setup({
            log_level = vim.log.levels.DEBUG,
            ui = {
                icons = {
                    server_installed = '✓',
                    server_pending = '➜',
                    server_uninstalled = '✗',
                },
            },
        })
    end,
}

configured servers:

• ccls, installed by package manager
• sumneko_lua
• pyright
• taplo
• cmake

Expected behavior

this error shall be not reported.

LspInstallInfo output

command failed due this error. see the screenshot.

Installation log

This file is empty, because the servers I use are installed already.

I noticed that there always is one of pylsp and tflint in the error.

There seems to be a looped dependency...

• the nvim-lsp-installer.servers is required by nvim-lsp-installer.middleware,
• the nvim-lsp-installer.middleware is required by nvim-lsp-installer.servers.pylsp and nvim-lsp-installer.servers.tflint.

The error occurs here due to this dependency loop in my opinion.

Could you help confirm and fix it?

[williamboman]

Hello! I don't believe there's a cyclical dependency problem here as this require is not done in the module closure. I believe this is happening because lspconfig is not available in Neovim Lua's package.path - do you perhaps lazy-load lspconfig? (when nvim-lsp-installer is setup lspconfig needs to be available)

[zhang-stephen]

in my configuration, the nvim-lspconfig is loaded later than nvim-lsp-installer... I will verify this soon. thanks.
