title: Update npm package with fixed dependency from command line
body: <p>I have an npm package with a fixed version that has an update.<br>
  Example package.json extract:</p>
  
  <pre><code>devDependencies: {
     "someFixedVersionPackage": "1.0.0", //1.1.0 is latest
     "anotherFixedVersionPackage": "2.3.2", //2.3.4 is latest
  }
  </code></pre>
  
  <p>Does an npm command exist which installs the latest version of that package and updates the package.json, preferably all packages at once?</p>
  
  <p>To be clear, I want the package.json snippet above to be updated to this, in addition to the packages themselves being updated:</p>
  
  <pre><code>devDependencies: {
     "someFixedVersionPackage": "1.1.0", //latest
     "anotherFixedVersionPackage": "2.3.4", //latest
  }
  </code></pre>
  
  <p>Thank you.</p>
