Description

After migrating from version 2 to 3, I ran into a problem in the github runner when deploying to github pages.

...
jobs:
  deploy:
    name: Deploy to GitHub Pages
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v3
        with:
          node-version: 20.9.0
          cache: npm
      - name: npm install
        run: npm ci && npx docusaurus --version
      - name: Build website
        run: npm run build

As I managed to find out the problem lies in the fact that after the npx docusaurus --version command is executed the programme terminates with the status (exit 1), but if you use npx docusaurus -V then everything works correctly.

bash-5.2$ npx docusaurus --version
Usage:  <command> [options]

Options:
  -V, --version                                            output the version number
  -h, --help                                               display help for command

Steps to reproduce

1. Use .github/workflows
2. config

---
name: Deploy to GitHub Pages

on:
  push:
    branches:
      - main
    # Review gh actions docs if you want to further define triggers, paths, etc
    # https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#on

permissions:
  contents: write

jobs:
  deploy:
    name: Deploy to GitHub Pages
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v3
        with:
          node-version: 20.9.0
          cache: npm
      - name: npm install
        run: npm ci && npx docusaurus --version
      - name: Build website
        run: npm run build
      - name: Copy CNAME
        run: cp CNAME ./build/

Expected behavior

The expectation was that we would not have to redo gh flow and npx docusaurus --version would complete correctly as well as npx docusaurus -V

Actual behavior

npx docusaurus --version terminates differently than npx docusaurus -V.

Your environment

• Public source code: -
• Public site URL: -
• Docusaurus version used: 3.4.0
• Environment name and version (e.g. Chrome 89, Node.js 16.4): node 20.9.0
• Operating system and version (e.g. Ubuntu 20.04.2 LTS): macOS 14.5 (23F79)

Self-service

• I'd be willing to fix this bug myself.

I have checked the repo. Love to work on this issue. Could you assign me this.

Thanks for reporting, this will be fixed in #10368

By the way, we'll also print the version instead of the help because this is what the command should have done in the first place. Currently it doesn't even print the version.
