Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

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

When using the npm2yarn plugin, if you specify the shorthand command npm start, the plugin will display an error # couldn't auto-convert command when the Yarn tab is selected.

If you provide the full command npm run start then there are no errors displayed in the Yarn tab.

2. Click the "Docusaurus Tutorial - 5min" button to be taken to the "./docs/intro.md"
3. Overserve the npm2yarn code blocks.

Expected behavior

Actual behavior

An error is displayed # couldn't auto-convert command

Indeed this issue exist in 2.3.1, but it's already fixed in main and planned to be backported for 2.4

Fixed as part of #8690

If someone gets the same error today, maybe the initial command is incorrect.

For example, I use pnpm and forgot that sometimes npm and pnpm commands are different.
My mistake was that I used npm create something instead of npm init something.

So I just wrote the correct npm command, and it works for me.
