telescope can not find files with neovim installed by snap

[TioeAre]

Description

When I use nvim installed with snap, I cannot use telescope normally. No error is reported, but all search functions cannot be used, nor can I switch the telescope version. This picture show it with nvim on path of ~/

Neovim version

checkhealth telescope

==============================================================================
telescope: require("telescope.health").check()

Checking for required plugins ~
- OK plenary installed.
- OK nvim-treesitter installed.

Checking external dependencies ~
- OK rg: found ripgrep 12.1.0 (rev 1980630f17)
- OK fd: found fd 7.4.0

===== Installed extensions =====

Steps to reproduce

1. use sudo snap install nvim --classic and use lazy.nvim to install telescope with ~/.config/nvim/lua/plugins/telescope.lua like this

   
   vim.g.mapleader = " "
   vim.g.maplocalleader = " "

local keymap = vim.keymap

local config = function() local telescope = require('telescope') telescope.setup({ defaults = { mappings = { i = { [''] = 'move_selection_next', [''] = 'move_selection_previous' } } }, pickers = { find_files = { theme = 'dropdown', previewer = false -- hidden = true }, live_grep = { theme = 'dropdown', previewer = false }, find_buffers = { theme = 'dropdown', previewer = false } } }) end

return { 'nvim-telescope/telescope.nvim', -- lazy = false, tag = '0.1.5', dependencies = {'nvim-lua/plenary.nvim', 'nvim-treesitter/nvim-treesitter'}, cmd = "Telescope", config = config, defaults = { file_ignore_patterns = {'node_modules', '.git'} }, keys = { { "ff", ":Telescope find_files", desc = "find files" }, { "fs", ":Telescope grep_string", desc = "grep string" }, { "fg", ":Telescope live_grep", desc = "live grep string" }, { "fr", ":Telescope resume", desc = "resume last search window" }} }

2. open `nvim .` and use `space+ff` to call telescope find files

Did you install ripgrep/fd using snap as well? If so, there's some privilege confinement rules that won't let those tools function properly within neovim.

[TioeAre]

no, I installed fd and ripgrep by apt . Should I increase the permissions of someone? Thank you very much.

[jamestrew]

Maybe neovim being installed via snap causes the issue as well. I'm far from an expert on snap but I don't think it's a permissions issue. I think it's the way snap installs and compiles programs. I think you can install it with flags to relax the confinement. I'm not entirely sure.

I would try using neovim's appimage to first see if the snap installation of neovim is the issue. We can continue from there.

I have found that telescope works well in the appImage version of nvim (from gitHub release), but I am still unsure why it is not functioning properly in the nvim installed via snap. So far, it seems that other plugins do not have this issue. I hope to draw the developers' attention to this matter. Thanks very much.

[jamestrew]

Thanks for confirming. I'm not sure why either. I'll leave this issue open until we can find a valid reason or fix.

I had same issue #2858 on archlinux, try to uninstall fd and ripgrep from your machine.

[TioeAre]

@aminerwx thanks for you recommend, but I am not sure if it is fd/ripgrep causes my problem, I have tried to Appimage instead of snap, and it works well, and there is just one version of fd/ripgrep in my machine installed by apt, The problem seems to become that neovim installed by Appimage can use fd/ripgrep installed by apt, but calling telescope in neovim installed by snap does not work properly. However, others such as lsp and treesitter can still work normally.

I am facing the same issue as well. The :checkhealth telescope command is showing all OK. But grep_find and file_preview are not working. I perform all the instructions from the official docs and also checked all the forums but the issue isn't resolving. Please fix this. I also installed nvim from snap store. The apt package manage should update the softwares, I had to use snap all the time because of the latest versions available but it creates problem all the time with the sudo and the user preferences.

FOUND MY SOLUTION

I checked in my machine the apt couldn't recognize the ripgrep. So I removed the ripgrep using sudo snap command, then installed it again with apt-get command. Now the grep and file preview is working fine. I suggest installing the ripgrep from apt-get. Dont install it from snap store.
