无法全局安装Ionic：npm报E404找不到@ionic/cli-framework@0.1.3

Let's walk through resolving this installation error step by step. First, here's the error you ran into for context:

npm ERR! code E404 npm ERR! 404 Not Found: @ionic/cli-framework@0.1.3
npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\User\AppData\Roaming\npm-cache_logs\2018-05-10T07_52_51_175Z-debug.log

This issue happens because the older version of Ionic CLI that npm install -g ionic tries to pull in depends on @ionic/cli-framework@0.1.3—a package version that's no longer available in the npm registry. Here's how to fix it:

• Uninstall any existing Ionic CLI (if present)
  Old, leftover CLI versions can cause conflicts. Remove them first with:

  npm uninstall -g ionic
  

• Clear your npm cache
  Outdated cached package metadata might be tricking npm into looking for the missing version. Clear it with:

  npm cache clean --force
  

• Install the latest official Ionic CLI package
  The modern, maintained Ionic CLI is now published under the @ionic/cli scope. Install it globally with:

  npm install -g @ionic/cli
  

• Optional: Update your npm version
  If you still hit snags, an outdated npm could be part of the problem. Update npm first:

  npm install -g npm
  

Once you've completed these steps, run ionic --version to confirm the CLI installed successfully.
