• I'd be willing to implement a fix

Describe the bug

running

yarn explain peer-requirements p2677a

first threw an error,

Unknown Syntax Error: Command not found; did you mean one of:

  0. yarn explain [--json] [code]
  1. yarn explain [--json] [code]

While running explain peer-requirement p6de1a

after yarn down and up grade it now throws

The yarn explain peer-requirements command doesn't support this warning type yet.

To reproduce

minimum package file

{
  "devDependencies": {
    "@angular-eslint/template-parser": "^15.2.1"
  },
  "packageManager": "yarn@4.0.2"
}

1. Just updated to 4.0.2

2. run yarn
   I got

   ➤ YN0002: │ root-workspace-0b6124@workspace:. doesn't provide eslint (p6936f), requested by @angular-eslint/template-parser.
   ➤ YN0002: │ root-workspace-0b6124@workspace:. doesn't provide typescript (p7ea97), requested by @angular-eslint/template-parser.
   ➤ YN0086: │ Some peer dependencies are incorrectly met; run yarn explain peer-requirements <hash> for details, where <hash> is the six-letter p-prefixed code.
   

3. run

    yarn explain peer-requirements p6de1a
   

   I got

   Unknown Syntax Error: Command not found; did you mean one of:
   
     0. yarn explain [--json] [code]
     1. yarn explain [--json] [code]
   
   While running explain peer-requirement p6de1a
   

4. Test no.1 downgraded to 4.0.1 -

   • yarn set version 4.0.1,
   • ran yarn etc. same result.

5. Test no.2 downgraded to 3.x, at first I got the same error running yarn explain ...,

6. after running it without hash

   yarn explain peer-requirement
   

   I got the list of peer-requirements with hashes, then yarn explain peer-requirements p6de1a worked.

7. Upgraded to 4.0.2, ran yarn etc. the message changed to

   $ yarn explain peer-requirements p6de1a
   
   The yarn explain peer-requirements command doesn't support this warning type yet.

The maintainer said in this PR: #5834

Note that I temporarily removed support for calling yarn explain peer-requirements on missing peer dependencies, as I'd like to take another look at those warnings in general (I noticed they aren't aggregated, but they probably should be too). Since they are fairly easy to understand by themselves, I don't feel like this is a significant regression.
