Environment

Note npx create-react-app --info is not working on Windows 10

System: Windows 10 NPM: 6.0.0 Node: 10.10.0 React-scripts: 1.1.5

Steps to Reproduce

1. npx create-react-app my-app-name
2. npm install -D babel-eslint
3. Modify App.js to include state as a class-property

class App extends Component {
  state = {
    message: "Hello React App"
  };
  render() {
    const { message } = this.state;
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h1 className="App-title">{message}</h1>
        </header>
        <p className="App-intro">
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

1. Run npm run build

Expected Behavior

I would expect the build to complete as expected.

Actual Behavior

The build fails with the error no-undef for the state that was defined in the component

PS C:\Node\windows-build-failure> npm run build

> windows-build-failure@0.1.0 build C:\Node\windows-build-failure
> react-scripts build

Reproducible Demo

As shown above, I can clone the repo and share if you wish, I only added a state class-property and installed babel-eslint.

In my real-world example I have a .eslintrc file for additional lint rules for VSCode to enforce more lint rules in development and pre-commit.

If I remove babel-eslint dependency the build will work.
