fix: correct the command to show help in README.md

[shi0rik0]

The old command will show the help of npm create, not the help of create-vue.

Description

Current documentation says we can use npm create vue@latest -- --help to show the help of create-vue, but I found it will print the help of npm create. I'm not sure if it's a bug of npm, but npx create-vue@latest -- --help works fine.

My Enviroment

Windows 11 + npm 10.9.0

Thanks for the PR

The npm create vue@latest -- --help command is correct on macOS and displays the help:

npm create vue@latest -- --help
Need to install the following packages:

Ok to proceed? (y)


> npx
> create-vue --help

Usage: create-vue [FEATURE_FLAGS...] [OPTIONS...] [DIRECTORY]

Create a new Vue.js project.
Start the CLI in interactive mode when no FEATURE_FLAGS is provided, or if the DIRECTORY argument is not a valid package name.

Options:
  --force
    Create the project even if the directory is not empty.
  --bare
    Create a barebone project without example code.
  --help
    Display this help message.
  --version
    Display the version number of this CLI.

The npx version that works for you on Windows sadly doesn't work properly on macOS and executes create-vue as if a project was created:

npx create-vue@latest -- --help

@cexbrayat I tried again and found that:

1. In cmd, the npm version works but the npx does not, jsut like on your MacOS.
2. In PowerShell, the npx version works but the npm does not.

This is interesting. I'll investigate it later.

Anyway, I believe that it's a problem related to npm.

@cexbrayat OK, I think I found out the answer. It's the PowerShell who is causing this problem behind the scene. According to my test and this question, the syntax of PowerShell will treat -- specially, so executing npm create vue@latest -- --help will be treated as npm create vue@latest --help. A solution is to use npm create vue@latest '--' --help.

Do you think we should add a notice about this for Windows users?

Yes, maybe you can add a mention for Powershell users 👍
