vtsls (lazyextra typescript) is not in correct place

[ahsanu123]

today, i try to install fresh LazyVim in my wsl arch linux, its working well, but when i try to install vtsls with mason (lazyextra, typescript), its give me error like this

[ERROR][2025-07-01 12:04:05] ...p/_transport.lua:36	"rpc"	"vtsls"	"stderr"	"node:internal/modules/cjs/loader:1408\n  throw err;\n  ^\n\nError: Cannot find module '/home/ah/.local/share/nvim/mason/@vtsls/language-server/bin/vtsls.js'\n    at Module._resolveFilename (node:internal/modules/cjs/loader:1405:15)\n    at defaultResolveImpl (node:internal/modules/cjs/loader:1061:19)\n    at resolveForCJSWithHooks (node:internal/modules/cjs/loader:1066:22)\n    at Module._load (node:internal/modules/cjs/loader:1215:37)\n    at TracingChannel.traceSync (node:diagnostics_channel:322:14)\n    at wrapModuleLoad (node:internal/modules/cjs/loader:235:24)\n    at Module.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:152:5)\n    at node:internal/main/run_main_module:33:47 {\n  code: 'MODULE_NOT_FOUND',\n  requireStack: []\n}\n\nNode.js v24.2.0\n"

vtsls.js is actually installed on $MASON__ROOT/package/vtsls/node_modules/@vtsls/language-server/bin/vtsls.js and not in $MASON_ROOT/@vtsls/language-server/bin/vtsls.js, so i try to copy as to error location and its work as expected.

i try to investigate further, and found as below.

I am not sure why, but basedir seem not having correct value

the echo $(echo "$0" | sed -e 's,\\,/,g') is return -zsh ( i am running zsh) or should it -z sh?? i am not sure, what basedir should be?

if i run my terminal with bash it return current directory (bin),

[ah@DESKTOP-HD67VPS bin]$ bat vtsls

   1   │ #!/bin/sh
   2   │ basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
   3   │
   4   │ case `uname` in
   5   │     *CYGWIN*|*MINGW*|*MSYS*)
   6   │         if command -v cygpath > /dev/null 2>&1; then
   7   │             basedir=`cygpath -w "$basedir"`
   8   │         fi
   9   │     ;;

  12   │ if [ -x "$basedir/node" ]; then
  13   │   exec "$basedir/node"  "$basedir/../@vtsls/language-server/bin/vtsls.js" "$@"
  14   │ else
  15   │   exec node  "$basedir/../@vtsls/language-server/bin/vtsls.js" "$@"
  16   │ fi

 $ echo $(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
.
[ah@DESKTOP-HD67VPS bin]$ pwd
/home/ah/.local/share/vnvim/mason/bin
[ah@DESKTOP-HD67VPS bin]$

so full path from $basedir is /home/ah/.local/share/vnvim/mason/bin/../@vtsls/language-server/bin/vtsls.js which is invalid.
and that also error that come out at the beginning /home/ah/.local/share/vnvim/mason/@vtsls/language-server/bin/vtsls.js

Still Looking for Solution 😄

[ahsanu123]

for context, i already start a discussion in lazyvim repo LazyVim/LazyVim#6215 (i had close it) , but its seem a mason problem because the runner script is platform independent (the vtsls.cmd in windows, and vtsls shell script in linux).

[ahsanu123]

Ok I am back with solution. (Disclaimer i am noob linux user).

Note:

• mason will use difference script based on your os to run lsp/bin ( i run on WSL 2)

For example this pyright 
~/.local/share/nvim/mason/packages/pyright/node_modules/.bin ⌚ 10:51:28
$ ls
pyright      pyright-langserver      pyright-langserver.ps1   
pyright.cmd  pyright-langserver.cmd  pyright.ps1

• this vtsls also occur for pyright

way to solve

to solve this vtsls / pyright cant find module

you need change basedir variable to use readlink -f because its linked and using only echo $0 will outputing current folder

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

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

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.
