I get this error in my typescript vite project. It was working before for a long time until after I updated yesterday. Here is my package.json:

Can you share your tsconfig(s) and the project structure? In the mean time you can try setting the bin_path configuration option.

[Armadillidiid]

It's a company repository, so unfortunately, I am unable to provide detailed information about the project structure. However, I can tell you that the tsconfig file is generally the default configuration generated by Vite when initializing a new project.

Regarding your question about setting the bin_path configuration, could you please provide more context or specify how I could do that?

[dmmulroy]

There is a bin_path config option that you can set to the path to your tsc binary. See #26 for more details.

[Armadillidiid]

I get the following error with the default configuration in the docs. Do I have to manually implement the utils function?

Error notify.error lazy.nvim Failed to run config for tsc.nvim

/home/xxx/.config/LazyVim/lua/plugins/tsc-nvim.lua:7: attempt to index global 'utils' (a nil value)

Config:

return {
  "dmmulroy/tsc.nvim",
  config = function()
    require("tsc").setup({
      auto_open_qflist = true,
      auto_close_qflist = false,
      bin_path = utils.find_tsc_bin(),
      enable_progress_notifications = true,
      flags = {
        noEmit = true,
        project = function()
          return utils.find_nearest_tsconfig()
        end,
      },
      hide_progress_notifications_from_history = true,
      spinner = { "⣾", "⣽", "⣻", "⢿", "⡿", "⣟", "⣯", "⣷" },
    })
  end,
}

I also tried manually adding the bin path to my global installed tsc, but it couldn't still find it.

lrwxrwxrwx 1 name wheel 38 Jul 9 17:56 tsc -> ../lib/node_modules/typescript/bin/tsc

Second confg:

return {
  "dmmulroy/tsc.nvim",
  config = function()
    require("tsc").setup({
      auto_open_qflist = true,
      auto_close_qflist = false,
      bin_path = "/lib/node_modules/typescript/bin/tsc",
      enable_progress_notifications = true,
      flags = {
        noEmit = true,
        project = function()
          return utils.find_nearest_tsconfig()
        end,
      },
      hide_progress_notifications_from_history = true,
      spinner = { "⣾", "⣽", "⣻", "⢿", "⡿", "⣟", "⣯", "⣷" },
    })
  end,
}

[dmmulroy]

Could you try this

return {
  "dmmulroy/tsc.nvim",
  config = function()
    require("tsc").setup({
      bin_path = "/lib/node_modules/typescript/bin/tsc",
    })
  end,
}

To use utils you'll need to require it like let tsc_utils = require('tsc.utils'), however I would expect the configuration I posted above to work.

By default bin_path is set for you at runtime using utils.find_tsc_bin() which work like this:

M.find_tsc_bin = function()
  local node_modules_tsc_binary = vim.fn.findfile("node_modules/.bin/tsc", ".;")

  if node_modules_tsc_binary ~= "" then
    return node_modules_tsc_binary
  end

  return "tsc"
end

It essentially recursively searches upwards from the current buffers directory for node_modules/.bin/tsc until it hits your project root. If it's unsuccessful it defaults to just tsc which would be a global installation of tsc.

Then when you run the plugin this code executes:

  local tsc = config.bin_path

  if not utils.is_executable(tsc) then
    vim.notify(
      format_notification_msg(
        "tsc was not available or found in your node_modules or $PATH. Please run install and try again."
      ),
      vim.log.levels.ERROR,
      get_notify_options()
    )

    return
  end

I'm assuming that invoking which tsc yields /lib/node_modules/typescript/bin/tsc?

[dmmulroy]

I also just installed a fresh project using npm create vite@latest my-vite-app -- --template vanilla-typescript and everything worked using the default config (require("tsc").setup()), so you may need to add some logging to the plugin or call utils.find_tsc_bin() from the status line cmdline (e.g. :lua print(vim.inspect(require('tsc.utils').find_tsc_bin())))

[Armadillidiid]

No, invoking which tsc returns ~/.local/bin/tsc, which is a symlink to /lib/node_modules/typescript/bin/tsc . Therefore, I opted to use that instead. In any case, I managed to get it working by utilizing the utility function you provided. I had ChatGPT to make any corrections if needed and it worked. Specifying the bin_path never worked, nor did requiring the tsc.utils.

Here's the working configuration:

local utils = {}

utils.find_tsc_bin = function()
  local node_modules_tsc_binary = vim.fn.findfile("node_modules/.bin/tsc", ".;")

  if node_modules_tsc_binary ~= "" then
    return node_modules_tsc_binary
  end

  return "tsc"
end

return {
  "dmmulroy/tsc.nvim",
  config = function()
    require("tsc").setup({
      bin_path = utils.find_tsc_bin(),
    })
  end
}

[dmmulroy]

That's really bizarre. You should at least be able to simplify that to just:

return {
  "dmmulroy/tsc.nvim",
  config = function()
    require("tsc").setup({
      bin_path = require('tsc.utils').find_tsc_bin(),
    })
  end
}

I wonder if vim.fn.executable[^1][^2] is doing something unexpected

executable({expr}) executable() This function checks if an executable with the name {expr} exists. {expr} must be the name of the program without any arguments. executable() uses the value of $PATH and/or the normal searchpath for programs. PATHEXT On MS-Windows the ".exe", ".bat", etc. can optionally be included. Then the extensions in $PATHEXT are tried. Thus if "foo.exe" does not exist, "foo.exe.bat" can be found. If $PATHEXT is not set then ".exe;.com;.bat;.cmd" is used. A dot by itself can be used in $PATHEXT to try using the name without an extension. When 'shell' looks like a Unix shell, then the name is also tried without adding an extension. On MS-Windows it only checks if the file exists and is not a directory, not if it's really executable. On Windows an executable in the same directory as Vim is always found (it is added to $PATH at |startup|). The result is a Number: 1 exists 0 does not exist -1 not implemented on this system |exepath()| can be used to get the full path of an executable.

[evanrichards]

I was also hitting this issue. For whatever reason running :echo vim.fn.findfile("node_modules/.bin/tsc", ".;") gave me nothing, but running :echo vim.fn.findfile("node_modules/.bin/tsc") spit out the correct tsc path. I updated my config setup to look like this:

require("tsc").setup({
    auto_open_qflist = true,
    auto_close_qflist = false,
    bin_path = vim.fn.findfile("node_modules/.bin/tsc"),
    enable_progress_notifications = true,
    flags = {
        noEmit = true,
        project = function()
            return vim.fn.findfile("tsconfig.json")
        end,
    },
    hide_progress_notifications_from_history = true,
    spinner = { "⣾", "⣽", "⣻", "⢿", "⡿", "⣟", "⣯", "⣷" },
})

note that i hit the same issue in the project file flag config.

[dmmulroy]

@evanrichards do you think you could replicate the issue in a small repo and post it?

[sami616]

Very strange this also seems to be an issue here, im working in a pnpm monorepo with build = true set.

[dmmulroy]

@sami616 Could you create a small pnpm monorepo where this is reproducible? I've never used pnpm or it's monorepo capabilities before.

did overiding the settings as @evanrichards work?

[dmmulroy]

@sami616 could you try using this config

require("tsc").setup({
    flags = {
        noEmit = false,
        build = true,
        project = false,
    },
})

[dmmulroy]

Closing this as stale - please let me know if you or anyone encounters this

[GitMurf]

@dmmulroy fyi I just started using your awesome plugin and I ran into similar issues. I also use pnpm as someone above mentioned but I don't think that should be a problem. I think potentially the problem is due to windows and likely path issues (backslashes vs forward, escaping, spaces in paths etc.). This is the most common issue I have ran into with many plugins in the neovim community. Curious if you have had a chance to test on windows?

That all being said, my solution was that I could use the defaults as provided in the readme except I had to change it to use bin_path = "tsc". All is working nicely after making this change.

[dmmulroy]

@GitMurf thanks for the details! Pnpm and workspaces have been a thorn in my side for this plugin haha. Is there any chance you could create a small repo where the bug is reproducible?

[GitMurf]

Yes but may take me a week or so. Swamped right now as I'm sure you understand ;)

Again, awesome work on this plugin! Absolute game changer for me for typescript development :)

[HadiModarres]

I cannot run TSC as it complains tsc was not found. Why can't we just use npx tsc to find where tsc is automatically, instead of providing it manually through bin_path?
