Cannot display the language server help page

[gautaz]

🐞 bug report

Is this a regression?

Tested with versions 16.0.0 and 13.3.4.

Description

The server README.md states:

Usage
See node index.js --help

For now, I have been unable to display this documentation page.

Bug Type

It is quite difficult to start using the language server without even being able to access its documentation.

• Angular Language Service VSCode extension
• Angular Language Service server

Reproduction

I have followed these steps:

mkdir test-ngserver && cd test-ngserver
npm init -y
npm install @angular/language-server
cd node_modules/@angular/language-server/
node index.js --help

which leads to the following stack trace:

/home/gautaz/test-ngserver/node_modules/@angular/language-server/index.js:235
      throw new Error(`Failed to resolve '${packageName}' with minimum version '${minVersion}' from ` + JSON.stringify(probeLocations, null, 2));
      ^

Node.js v18.14.2

Expected behavior

After installing the language server, the help page should be available without needing any additional dependency.

If a particular language server installation process is to be followed, this process should be accessible from the language server README.md page.

Logs

See Reproduction.

N/A

🌍 Your Environment

Angular Version:

This feels strange, if the language server relies on external dependencies
to display its help page (like other angular packages), shouldn't the language
server README.md state what these dependencies are and how they are accessed
by the language server?

Extension Version:

I am not using the vscode extension, I am only trying to start the
language server (tested with versions 16.0.0 and 13.3.4)

VSCode Version:

I am using Neovim, I am only trying to use the language server,
no vscode in the picture.

Operating System:

❯ uname -a
Linux dante 6.1.32 #1-NixOS SMP PREEMPT_DYNAMIC Mon Jun  5 07:26:22 UTC 2023 x86_64 GNU/Linux

Extension options:

N/A, I am not using the vscode extension.

Anything else relevant?

Nothing I can think of but I would be happy to provide any additional information.
