JSX error: Property does not exist on type 'JS

Question

I converted my Container into a .jsx file, but now I'm getting the following errors on my HTML elements in the render method:

Property does not exist on type 'JSX.IntrinsicElements.div

Property does not exist on type 'JSX.IntrinsicElements.h1

loginContainer.js

    import * as React from 'react';
import { connect } from 'react-redux';

// Actions
// import { addCoins } from 'actions/coins';

interface IProps {
  loginActions: any
}

interface IState {
  email: string;
  password: string;
}

class LoginContainer extends React.Component<IProps, IState> {

  public state: IState = {
    email: '',
    password: ''
  };

  public render() {
    return (
      <div id="login-container">
        <h1>Login</h1>
      </div>
    );
  }
}

// const mapDispatchToProps = dispatch => ({
//   addCoins: (...args) => dispatch(addCoins(...args))
// });

export const LoginContainerJest = LoginContainer;

export default connect(null, null)(LoginContainer);

I've rm -R node_modules, I also did see that I had "@types/react-redux" installed twice, but I fixed that. Reinstalled Typescript, and still get the same (2312,14): Duplicate identifier 'LibraryManagedAttributes'. Error :(

Found the answer: Typescript Error: TS2339: Property 'span' does not exist on type 'JSX.IntrinsicElements'

• Make sure you have import * as React from 'react' in your file
• Update types for react npm install @types/react
