## Troubleshooting

If your project is not created with TypeScript enabled, npx may be using a cached version of `create-react-app`. Remove previously installed versions with `npm uninstall -g create-react-app` or `yarn global remove create-react-app` (see [#6119](https://github.com/facebook/create-react-app/issues/6119#issuecomment-451614035)).

If you are currently using [create-react-app-typescript](https://github.com/wmonk/create-react-app-typescript/), see [this blog post](https://vincenttunru.com/migrate-create-react-app-typescript-to-create-react-app/) for instructions on how to migrate to Create React App.

Constant enums and namespaces are not supported, you can learn about the constraints of [using Babel with TypeScript here](https://babeljs.io/docs/en/babel-plugin-transform-typescript#caveats).

- If you've added TypeScript and you are using eslint you may need to update your `.eslintrc.json` file to specify the parser:
```
"parser": "@typescript-eslint/parser",
