  <blockquote>
    <p>error TS6053: File 'xxx.ts' not found.</p>
  </blockquote>
  
  <p>but the files compiles fine yesterday, but today no, after reviewing, I made this simple test</p>
  
  <pre><code>class HelloWorld {
  
      public static main(): number{
  
      return 0;    
      }
  }
  HelloWorld.main();
  </code></pre>
  
  <p>but I get the same error, anyone know the reason for this or may be the error</p>

  <p><strong>UPDATE:</strong></p>
  
  <p>Closing the ide, and open the error does not solve everything was the same.</p>
  
  <p>Opened the ide, </p>
  
  <p><kbd>file</kbd> > <kbd>folder close</kbd></p>
  
  <p><kbd>file</kbd> > <kbd>open folder</kbd> > your folder</p>
  
  <p>this fix the error.</p>
