Docusaurus can't be initialized with pnpm

[3x071c]

🐛 Bug Report

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io
• I have read the console error message carefully (if applicable)

Description

Attempting to initialize a new docusaurus project fails with Excess arguments when using pnpx:

$ pnpx -y @docusaurus/init@latest init my-website classic
Packages: +39
+++++++++++++++++++++++++++++++++++++++
Packages are cloned from the content-addressable store to the virtual store.
  Content-addressable store is at: /home/<user>/.pnpm-store/v3
  Virtual store is at:             node_modules/.pnpm

/home/<user>/.pnpm-store/v3/tmp/_npx/50290/5:
+ @docusaurus/init 2.0.0-beta.3

Progress: resolved 39, reused 39, downloaded 0, added 39, done
Excess arguments.

npx works, as well as installing and using docusaurus with pnpm afterwards:

$ npx -y @docusaurus/init@latest init my-website classic --skip-install && cd my-website && pnpm i

pnpx belongs to pnpm, a relatively new package manager which avoids dependency trouble and high disk space usage by using hard links from a global store and not flattening node_modules. While I was able to work around this so easily it's almost not worth an issue (as seen above), it would be nice if docusaurus would be smooth to initialize for pnpm users as well.

Is it 100% sure it's a Docusaurus bug?

Have you checked pnpm repo for issues? There are a few that looks related:

If so, what's the usual way for making a package initializable with pnpm, that diverge from the other tools?

Are you sure your init command is correct and another syntax is not required for extra cli args with pnpx?

Don't really have time to look into this rn, sorry...
