Question

After installing via typings I get the below error in terminal

Terminal error

error TS2320: Interface 'Element' cannot simultaneously extend types 'ReactElement<any>' and 'ReactElement<any>'.
  Named property 'type' of types 'ReactElement<any>' and 'ReactElement<any>' are not identical.

tsconfig.json

{
  "compilerOptions": {
    "module": "commonjs",
    "sourceMap": true,
    "noImplicitAny": true,
    "target": "es5",
    "jsx": "react"
  },
  "files": [
    "./app/app.tsx",
    "./app/Hello.tsx",
    "typings/index.d.ts"
  ],
  "exclude": [
      "node_modules"
  ]
}

I have followed the documentation provided in https://www.typescriptlang.org/docs/handbook/react-&-webpack.html

Not sure what I have missed?

Is anyone facing this issue?

Answer 1

I figured out the issue finally.

I went on to install types once via tsd and then typings that led to duplicate typings.

Deleted the @types folder to resolve my issue.

Answer 2

Just in case anyone else stumbles into this, I also got this error when there was a mismatch between my @types/react and @types/react-dom packages. I ended up just deleting the @types/react entry in my package.json since it's automatically included by @types/react-dom .
