Formatter not executable error

[BennyThadikaran]

I get the below error in Neovim when opening a Lua file. The problem started yesterday after I updated to latest guard.nvim. I then updated Neovim to latest and updated the formatters via Mason and rechecked the formatter config. I also tried reinstalling the formatters and guard.nvim.

Switched to autopep8 but nothing seems to work. Even :GuardFmt

Failed to run `config` for guard.nvim

Disabling stylua stops the error in Lua files but i get a slightly different error with same stack trace when loading Python or JSON files

      args = { "-s", "-l", "80", "-" },
      stdin = true,

    require("guard").setup({

      lsp_as_default_formatter = false,
    })
  end,
}

Some command outputs i thought might help

:checkhealth guard If neovim can't find the executables, there's not much that we can do!

[BennyThadikaran]

I executed this from a python file after this error: stylua not executable

guard: require("guard.health").check()

Executable check ~

• OK black found
• OK stylua found
• OK npx found

Thank you for helping with this.

[xiaoshihou514]

That's not very helpful, are you on windows?

[BennyThadikaran]

Linux Mint 21.3. I am using an appimage for Neovim.

[xiaoshihou514]

which stylua
stylua --version

:= vim.fn.executable("stylua")

[BennyThadikaran]

stylua 0.20.0

black, 24.4.2 (compiled: yes) Python (CPython) 3.10.12

I'm dont need stylua, mostly code in Python. I got this temporary solution as workaround.

vim.api.nvim_create_augroup("FormatOnSave", { clear = true })

vim.api.nvim_create_autocmd("BufWritePre", {
  group = "FormatOnSave",
  pattern = "*.py",
  callback = function()
    local black_path = '/home/benny/.local/share/nvim/mason/bin/black'
    vim.cmd('!' .. black_path .. ' -q -l 80 ' .. vim.fn.expand('%'))
    vim.cmd('edit')
  end,
})

[xiaoshihou514]

Right, so what's your problem now? I'm getting rather confused.

[BennyThadikaran]

Like i mentioned before, none of the formatters are working anymore (Prettier, Black, Stylua). No formatting on save, no :GuardFmt

Everything was working before the latest update. It fine, if you're unable to help with the information provided.

Thanks for your time :+1: I'll figure something over the weekend.

@BennyThadikaran does this path /home/benny/.local/share/nvim/mason/bin in your PATH env ?

[xiaoshihou514]

Well, the errors told you that they are not executable. But your env seemed to have changed between replies, which confuses me.

[glepnir]

check :echo executable('where balck is') I suggest install bacl from your system package management and remove which install by mason and try again.

[BennyThadikaran]

@BennyThadikaran does this path /home/benny/.local/share/nvim/mason/bin in your PATH env ?

No its not.

check :echo executable('where balck is') I suggest install bacl from your system package management and remove which install by mason and try again.

That makes sense. I executed :echo executable('where black is') and it returned 0. I will install and get back.

Thanks

PS: I executed ./stylua --version from the mason/bin folder, since its not in my $PATH. Sorry if that got you confused.
