title: Your package name is invalid - Composer 2.0
body: <p>I'm trying to composer-install and I get the following error <code>Your package name access-nyc is invalid, it should have a vendor name, a forward slash, and a package name.</code>
  I have the following in my package name:</p>
  
  <pre><code>{
    "name": "access-nyc",
    "version": "3.8.1",
    "description": "Find help in NYC with food, money, housing, work and more on ACCESS NYC",
    "homepage": "https://access.nyc.gov",
    "authors": [
      {
        "name": "NYC Opportunity",
        "email": "products@nycopportunity.nyc.gov",
        "homepage": "http://nyc.gov/opportunity"
      },
      {
        "name": "Blue State Digital",
        "homepage": "https://www.bluestatedigital.com"
      }
    ],
    "repositories": [
      {
        "type": "composer",
        "url": "https://wpackagist.org"
      }
    ],
  </code></pre>
  
  <p>This is the package name that breaks, <code>"access-nyc"</code> but to me it looks good. What is the problem?</p>
