create-react-app with typescript not working

Question

I want to create a typescript react app by using this tool Microsoft/TypeScript-React-Starter . I have followed the instructions from the github page:

1. npm install -g create-react-app

2. create-react-app my-app --scripts-version=react-scripts-ts

3. cd my-app

4. npm start

Then I get this error:

error TS2304: Cannot find name 'process'

I have uninstalled create-react-app and reinstalled it. The error persists. By the way yesterday I created a test program with the same tool and it worked. When I run this test program, it works as expected.

But whatever application I create today with the tool throws the above exception. I think my installation is corrupted some how.

Any help would be greatly appreciated.

Answer 1

Going back to typescript version 2.3.4 worked for me.

I used:

npm install typescript@2.3.4
