title: NPM : how to just run post-install?
body: <p>Just a simple question : in my node.js project, how could I just run the postinstall script, without running install before ?</p>
  
  <p>FYI, this is my package.json :</p>
  
  <pre><code>{
    "name": "gestionclientjs",
    ...,
    "dependencies": {
      ...
    },
    "repository": {},
    "devDependencies": {
      ...
    },
    "engines": {
      "node": "&gt;=0.10.0"
    },
    "scripts": {
      "test": "grunt test",
      "postinstall" : "bower install &amp;&amp; node ./app/server/dbSeed.js",
      "start": "node app/server/app.js"
    }
  }
  </code></pre>
  
  <p>For now, I run :</p>
  
  <pre><code>npm install
  </code></pre>
  
  <p>in my project, but I want to run</p>
  
  <pre><code>npm postinstall
  </code></pre>
  
  <p>when I want (and when I'm sure dependencies are ok). </p>
