```

i know script inside **bin** is linked to real binary for every package ( at least for this npm installed package).

> [!NOTE]
> I am not sure if it fixed in latest version, should i report to lazyvim instead? but i believe it from mason config

## Solution I Found
to solve this **vtsls** / **pyright** cant find module

```shell
[ERROR][2025-07-29 09:29:19] ...p/_transport.lua:36 "rpc" "pyright-langserver" "stderr"

you need change **basedir** variable to use `readlink -f` because its linked and using only `echo $0` will outputing _current folder_

```shell

//from
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

// to
basedir=$(dirname $(readlink -f $0) | sed -e 's,\\,/,g')
```

```shell
~/.local/share/nvim/mason/bin ⌚ 10:59:19
$ ls -lar
total 36

lrwxrwxrwx 1 ah ah 81 Jul 29 09:22 lua-language-server -> /home/ah/.local/share/nvim/mason/packages/lua-language-server/lua-language-server
```

after changing `echo $0` to `readlink -f $0` its work as expected. i am not sure with other env like `*CYGWIN* | *MINGW* | *MSYS*`, but at least it work for me.

### Expected behavior

vtslss / pyright should work on typescript / python file.

### Steps to reproduce

1. install fresh neovim with lazyvim, **on WSL** (archlinux)
2. install lazyextra for python / typescript lang
3. restart nvim, mason will download package
4. try to open typescript / python.

### Affected packages

npm installed package (i only try on vtsls and pyright)

### Neovim version (>= 0.10.0)

$ nvim --version
NVIM v0.11.3
Build type: RelWithDebInfo
LuaJIT 2.1.1753364724
Run "nvim -V1 -v" for more info

### Operating system/version

Linux DESKTOP-HD67VPS 6.6.87.2-microsoft-standard-WSL2 #1 SMP PREEMPT_DYNAMIC Thu Jun 5 18:30:46 UTC 2025 x86_64 GNU/Linux

### Screenshots or recordings

_No response_

Inspect the generated launchers under ~/.local/share/nvim/mason/bin and their linked npm package .bin targets for vtsls and pyright. Reproduce the WSL installation steps, then compare how the launcher resolves its directory through the symlink. Done means both language servers start successfully and work on TypeScript and Python files without MODULE_NOT_FOUND errors.
