title: Could not find a declaration file for module. '/path/to/module-name.js' implicitly has an 'any' type
body: <p>I am going through the Gatsby.js tutorial and in tutorial two, you have to import some fonts. When I try to import <code>theme lawton</code> I see this error under <code>import lawtonTheme from "typography-theme-lawton";</code></p>
  
  <p>I first did <code>npm install --save typography-theme-lawton</code></p>
  
  <pre><code>  Could not find a declaration file for module 'typography-theme-lawton'. '/Users/react/tutorial-part-two/node_modules/typography-theme-lawton/dist/index.js' implicitly has an 'any' type.
    Try `npm install @types/typography-theme-lawton` if it exists or add a new declaration (.d.ts) file containing `declare module 'typography-theme-lawton';`
  </code></pre>
  
  <p>This is my typography.js file:</p>
  
  <pre><code>import Typography from "typography";
  //import bootstrapTheme from " typography-theme-bootstrap";
  import lawtonTheme from "typography-theme-lawton";
  
  const typography = new Typography(lawtonTheme);
  
  //const typography = new Typography({ baseFontSize: "18px" });
  //const typography = new Typography(bootstrapTheme);
  
  export default typography;
  </code></pre>
  
  <p>This is my gatsby-config.js file:</p>
  
  <pre><code>  module.exports = {
    plugins: [
      {
        resolve: `gatsby-plugin-typography`,
        options: {
          pathToConfigModule: `src/utils/typography.js`
        }
      }
    ]
  };
  </code></pre>
  
  <p>Also in the gatsby-config file, the word module is underline and this note shows:
  <code>[ts] File is a CommonJS module; it may be converted to an ES6 module. [80001]</code></p>
  
  <p>I also tried <code>npm install @types/typography-theme-lawton</code> but it gave me errors</p>
