title: Problem with installing react dependencies
body: <p>I am trying to install react using this command: <code>npx create-react-app .</code></p>
  <p>Then I tried to run using this command: <code>npm run start</code></p>
  <p>Then I get this error:</p>
  <pre><code>There might be a problem with the project dependency tree.
  It is likely not a bug in Create React App, but something you need to fix locally.
  
  The react-scripts package provided by Create React App requires a dependency:
  
    &quot;webpack-dev-server&quot;: &quot;3.10.3&quot;
  
  Don't try to install it manually: your package manager does it automatically.
  However, a different version of webpack-dev-server was detected higher up in the tree:
  
    C:\Users\oa\Desktop\node_modules\webpack-dev-server (version: 3.11.0)
  
  Manually installing incompatible versions is known to cause hard-to-debug issues.
  
  If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
  That will permanently disable this message but you might encounter other issues.

  <p>As suggested here [https://stackoverflow.com/questions/42308879/npm-err-code-elifecycle][1] ,
  I have tried to fix it using the following commands:</p>
  <pre><code>delete package-lock.json
  npm cache clean --force
  npm install
  npm start 
  </code></pre>
  <p>But did not fixed for me.</p>
  <p>Just to let you know, my npm version is <code>6.13.6</code>, and node version is <code>v13.8.0</code></p>
