安装ember-cli-mirage时触发构建错误，无法加载Ember应用

Hey there, let's work through this build error you're hitting when installing ember-cli-mirage for your Ember 2.8 app. First, I notice your terminal is warning that Node v8.9.1 hasn't been tested with Ember CLI—this is likely a key culprit since Ember 2.8 was released before Node 8 became widely supported. Here's what to try:

• Fix the Node version mismatch
  Ember 2.8 officially supports Node 4.x or 6.x. Using an untested Node version can cause unexpected dependency conflicts and build failures. I recommend using nvm (Node Version Manager) to switch to a compatible version:

  # Install nvm if you don't have it already
  # (Follow official setup steps for your OS)
  # Install Node 6 (the latest compatible version for Ember 2.8)
  nvm install 6
  # Switch to Node 6
  nvm use 6
  

  After switching, restart your terminal and try running ember s again.

• Reinstall dependencies to fix conflicts
  Sometimes partial or corrupted dependency installs can cause build issues. Let's start fresh:

  # Delete existing node modules and lock file
  rm -rf node_modules package-lock.json
  # Reinstall base dependencies
  npm install
  # Reinstall ember-cli-mirage with a version compatible with Ember 2.8
  ember install ember-cli-mirage@0.3.1
  

  Specifying version 0.3.1 ensures you're using a Mirage release that was built to work with Ember 2.8—newer versions will have breaking changes that won't play nice with your older app.

• Grab the full build error log
  The terminal output you shared cuts off before showing the actual build error details. Next time you run ember s, let the process run until it fails, then copy the entire error message (including stack traces, module names, or syntax errors). That will help pinpoint exactly what's breaking—like a missing babel plugin or incompatible module.
