title: downgrade to babel 6.2.3
body: <p>I'm using react js and I installed babel 7 in my pc.
  when I open react js app with command</p>
  
  <blockquote>
    <p>npx create-react-app project_name</p>
  </blockquote>
  
  <p>and then i make</p>
  
  <blockquote>
    <p>yarn eject</p>
  </blockquote>
  
  <p>I get package.json (part of it)</p>
  
  <pre><code>"dependencies": {
  "@babel/core": "7.1.0",
  "@svgr/webpack": "2.4.1",
  "babel-core": "7.0.0-bridge.0",
  "babel-eslint": "9.0.0",
  "babel-jest": "23.6.0",
  "babel-loader": "8.0.4",
  "babel-plugin-named-asset-import": "^0.2.3",
  "babel-preset-react-app": "^6.1.0",
  "bfj": "6.1.1",
  </code></pre>
  
  <p>but I get some issues with babel 7 so i want to downgrade to last babel ^6.23.0".
  I installed it globally and when I run on cmd</p>
  
  <pre><code>babel --version
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>6.23.0 (babel-core 6.26.3)
  </code></pre>
  
  <p>but when I try to create new project again with
  create-react-app 
  I get the same babel core 7.0 but I don't want it.
  I want this babel (like my other projects)</p>
