title: Express.js/Typescript: Error TS2339: Property 'send' does not exist on type 'Response'
body: <p>I'm seeing this in Phpstorm 2019.3 with a red lint under .send()</p>
  
  <pre><code>// package.json
    "dependencies": {
      "express": "^4.17.1"
    },
    "devDependencies": {
      "@types/express": "^4.17.2",
      "tslint": "^5.12.0",
      "typescript": "^3.2.2"
    },
  
  // index.ts
  const express = require("express")();
  
  express.get('/', (req: Request, res: Response): void =&gt; {
   res.send('Express App Running') // TS2339: Property 'send' does not exist on type 'Response'
  });
  </code></pre>
  
  <p>Are these the wrong type definitions or is something else at play?</p>
